Proposal Review Process

Proposal Submissions

LaserNetUS encourages scientists from diverse fields to propose experiments utilizing the consortium’s wide-ranging capabilities. International Principal Investigators are welcome. We recommend that scientists describe well-posed experiments. Proposals must include brief discussions of the expected scientific or technological impact and anticipated feasibility and probability of success of experiments. Proposals that include a clear description of the expected schedule, indicating the scope, have a better chance of being selected.

Proposal Guidelines and Required Content

Title:

Provide a descriptive title of your proposed experiment that you would be willing to be make public if awarded facility time.
Abstract:

Character Limit: 1,900

Provide an abstract that concisely summarizes the proposed experiment. Emphasize the hypothesis to be tested, expected scientific results and impact. Indicate the observables to be measured (or the relevant experimental approach), samples to be studied etc. State the primary LaserNetUS facility.
Introduction:
Character Limit: 2,000

This should briefly introduce the topic including essential background, context, and references for a general, non-expert audience.

Consider the following questions to guide your writing:
- What is the topical area?
- What is the scientific importance of this topic and potential societal impact?
- What is the current state of knowledge, and where are the significant knowledge gaps or outstanding questions (and why)?
Scientific or Technical Case:
Character Limit: 5,000
Recommended: 1 figure

Focus on the scientific (or technical) objectives of the proposed experiments. This section should be highly detailed however it is important that it is thoroughly referenced such that reviewers from a related research area have adequate information to assess this work in the context of the topical area.

Use the following questions to guide your writing:
- What is the hypothesis to be tested, or what essential question is to be addressed in these experiments?
- What are the experimental observables, and how will these observables address the main scientific (or technical) objectives of the proposal? Modeling and/or prior results that can quantify the expected observables should be presented wherever possible – see “feasibility” section below.
- Describe how the experiment has been designed using theory, simulations, or previous work
- What measurements are required for the proposed experiment to be considered a success? If successful, what will be the impact on your topical area?
Provide a roadmap for the analysis and interpretation of the experimental measurements to answer the hypothesis/essential questions of this experiment. Consider including a description of the role of theory, simulations, or analysis methods post-experiment.
Experimental Details:
Experimental Details Character Limit: 2,000
Recommended: 1 figure

Proposals must contain sufficient information for LaserNetUS facility scientists to review the proposal for technical feasibility and/or suitability at the primary and secondary LaserNetUS facility. We strongly recommend that you contact the Point of Contact (POC) at your primary and secondary facility to schedule a meeting to discuss with the facility scientist(s) before proposal submission to discuss capabilities and to identify possible problems in integrating external equipment with the LaserNetUS facility and to determine possible solutions.

Note that additional experimental details of short-listed or awarded experiments will be requested at a later date. Thus, very fine details of the experiment do not need to be captured within the main proposal.

We make every effort to award experiments at the primary facility as we understand it is difficult to design and write a proposal that covers the complexities and differences at two different LaserNetUS facilities within the 6-page limit. The PRP will rank a proposal for the primary facility that was requested and will only consider it at the secondary facility if it was not competitive at the primary facility. If a proposal was not competitive at the primary or secondary facility, the PRP may recommend an alternative facility if available. In this case, the Spokesperson may accept or decline the transfer to the alternative facility.

Questions which will be used in the evaluation of the proposal:
- What is the primary and secondary LaserNetUS facility?
- Why is the primary LaserNetUS facility essential for this experiment? Be specific about the most important (unique) capabilities, instrumentation, expertise, partnerships, etc. that will enable the proposed experiment.
- What is the experimental set-up and/or procedure?
Consider the following additional questions, as applicable, to guide your writing:
- What previous experiments or development work has been performed? Describe any preliminary results, simulations, designs, or supporting experiments.
- What are the key elements of the proposed experimental set-up which are required for the successful execution of the experiment?
- If your proposed work relies on high-repetition rate to obtain a statistically significant measurement, what are the anticipated data rates?
- What additional key equipment (i.e., equipment that is not presently available at the LaserNetUS facility) is needed, including laser, detector, sample delivery/environment, temperature, pressure, etc.? What are the plans and timeline for securing this additional equipment (e.g., through collaboration, upcoming purchases)?
- How soon do you anticipate being ready for the experiment if notified in Spring 2023? This information will be used for scheduling purposes only and will not impact the ranking of your proposal by the PRP.
Feasibility assessment for Primary Facility:

Character Limit: 2,000
Required: 1 setup schematic, 1 table describing experiment schedule

Briefly describe the experiment setup or geometry. Provide a schematic diagram including key equipment and laser beam paths. The Point of Contact at each LaserNetUS facility can provide additional information and recommendations if assistance is required.

Each facility has table of key laser parameters on the LaserNetUS website: https://lasernetus.org/facilities/. Describe the required laser parameters such as wavelength, focal spot quality, repetition rate, pulse contrast, pulse energy, and pulse duration required for the proposed experiment. If anything beyond the parameters listed in the parameter table are required (e.g. polarization, bandwidth, chirp, etc.), provide a detailed description. Specify any timing and synchronization requirements.

Describe the targets and/or samples which will be used. Include any non-standard sample preparation, storage, or alignment that is required.

Describe any additional resources required (e.g., access to local facilities, labs, advanced testing, unique sample preparation, delivery storage requirement)

Describe any known risks which may prevent the successful execution of the proposed experiment such as sourcing targets, equipment (e.g., availability of equipment that will be loaned from another institution), or materials (e.g., new/untested manufacturer, long lead times). Are there any potential changes in personnel availability (e.g., PhD student graduating) during Cycle 5 which determine when the experiment could be performed?

Provide a table outlining the experiment schedule. The typical experiment duration awarded by LaserNetUS varies by facility – please discuss the number of days/shifts that should be requested for your experiment with the facility Point of Contact prior to submitting the proposal.
Feasibility assessment for Secondary Facility (Optional):

Character Limit: 1,000

Provide a summary of your assessment of the feasibility of this experiment at the secondary facility specifically focusing on any changes that would be required from the experimental design and/or scope if awarded time at the secondary facility.
Scientific Ecosystem Stewardship and Broader Impact:
Character Limit: 2,000

Workforce development and expanding the scientific ecosystem around the use of high-power lasers are key missions of LaserNetUS. In this section, we would like you to provide context for how the proposed work supports these values.

Questions which may be used in the PRP’s evaluation of the proposal:
- Does this proposal provide academic or training opportunities to students or early career researchers? If so, are the results of the proposed experiments for a thesis project?
- What is the intended audience for these results? What is the venue or format that the experimental results will be shared?
- Describe how this proposal will increase or sustain community interest in the topical area (e.g. follow up experiments, new funding applications/research programs)?
- To what extent does this proposal engage underrepresented groups or institutions?
Other questions you can consider, if applicable:
- Does this proposal engage with a new research group or institution that has not previously been involved with LaserNetUS?
- To what extent will the project enhance the scientific, technical, or engineering infrastructure of LaserNetUS and result in a potential asset for the larger community?
- Is the proposed work from a topical area which has not yet been awarded time through LaserNetUS?
- Is the proposed experiment part of a larger project or program (e.g., NNSA Center of Excellence, Laboratory Directed Research and Development (LDRD), multi-institutional agreements)
Appendix I - References:

The proposal should be thoroughly referenced. References should be numbered in the order in which they appear in the proposal in the following format [1], [4-7], [2, 3, 12-14].
Appendix II - Tentative Research Team Table:
Supporting Narrative Character Limit: 1,000 characters

User support varies significantly at the various LaserNetUS facilities. In some cases, the technical feasibility of your proposal will depend on the number of on-site personnel and their previous experience. This table will be used by the facilities to assess the technical feasibility and likelihood of successfully executing the experimental goals.

Definitions of experiment participation:
- On-site: individuals who will travel to the LaserNetUS facility to perform or supervise hands on work in the laboratory before or during the scheduled experiment
- Remote support: can vary by team but may include individuals who perform remote data analysis, supervision, coordination, or observation
- Not attending: individuals involved in other aspects such as pre-experiment design or post-experiment analysis and interpretation
For the key personnel on the tentative research team (e.g., Lead-PI, personnel who will field primary diagnostics, overall supervision), provide 1-3 sentences detailing:
- What is their role, responsibilities, or expected tasks?
- Where or how did the individual obtain the experience necessary for the proposed experiment? Provide description or references to publications.
- If applicable, what training or assistance will be required from the local facility personnel for their role, responsibilities, or expected tasks?
Example: First Name Last Name (Lead-PI) e.g has previously designed and led short pulse experiments using the ALEPH and Titan lasers. They have extensive experience in developing laser-pulse contrast enhancement setups1,2 and the generation and characterization of high-harmonic sources.3

Notes

Definition of Spokesperson and Lead PI
The ‘Spokesperson’ is the primary administrative contact for the proposed experiment. The ‘Lead PI’ typically conceives of the idea, designs the experiment, and leads the experimental team and analysis effort. In almost all cases, the Spokesperson and Lead PI are the same.  
Proposal Submissions as Student/Postdoc
A ‘Co-PI’ is required for all submissions when a student or postdoc is the Lead PI. In this case, the Co-PI is typically the supervisor/manager and is expected to provide the necessary training, oversight, funding, and resources to execute the experiment. Additionally, the Co-PI will be contacted if the student/postdoc leaves the field.
Tentative Research Team
A list of all participants that you expect to be involved in the proposed research is required. It should include students, designers/modelers, target fabrication technicians, etc. This information is collected in Appendix II - Tentative Research Team. This information is critical to assess if the team/collaboration has adequate experience and staffing levels are compatible with the support provided by the facility.
Safety
Safety related documents must be submitted during the safety management portion of the LaserNetUS proposal submission process in the user portal. List and describe any safety concerns that may arise with samples you will examine, equipment you will use, or techniques you will perform (including any physical, chemical or biological hazards) and how these issues will be addressed.
Cost
There is no cost to submit proposals or conduct experiments at the participating institutions. Users are generally responsible for their own travel and target expenses as well as any extraordinary consumables required by the experiment.
Designating Primary and Secondary Facility
Each proposal is for one specific experiment, with the option to designate first and second choice for a facility. The PRP will rank a proposal for the primary facility that was requested and will only consider it at the secondary facility if it was not competitive at the primary facility. If a proposal was not competitive at the primary or secondary facility, the PRP may recommend an alternative facility if available. In this case, the Spokesperson may accept or decline the transfer to the alternate facility.
Scientific Campaigns
Proposals may be made in the context of a larger scope than can be covered in a single experiment. All proposals, even these broader proposals that address important problems, must be resubmitted each cycle in order to be peer reviewed and considered for facility time. However, in the absence of sufficient information to evaluate progress (data disseminated from previous facility time, publications, etc.), the PRP may recommend that some proposal(s) be postponed for consideration until a future review cycle.
Publication Record from Previous LaserNetUS Experiments
In future calls, the PRP will pay particular attention to the applicants' publication record from prior LaserNetUS facility times. Failure to publish in a timely manner will impact the chances of a successful application in a similar area.
Resubmission
Proposals can be re-submitted at each call, but this will not happen automatically and a re-submission will not receive preference during the review process.
Multiple Submissions
Multiple submissions from the same team for similar experiments at different LaserNetUS facilities will not be considered. While there is no limit to the number of distinct proposals that can be submitted by a scientist or team, the Proposal Review Panel (PRP) may impose a relative advantage to the first-best proposal from each team.
Required Language
Proposal teams must acknowledge the host institution and DOE Office of Science in presentations and publications using the template: "This work was supported by DOE Office of Science, Fusion Energy Sciences under Contract No. [LaserNetUS contract number from facility]: the LaserNetUS initiative at [Facility]," and any other acknowledgement required by the host institution.

Changes since Cycle 4

The OMEGA EP Laser Facility at the University of Rochester’s Laboratory for Laser Energetics (LLE) will only be accepting proposals for LaserNetUS experiments related to inertial fusion energy (IFE) during Cycle 5.
The Texas Petawatt Laser (TPW) at the University of Texas at Austin (UT Austin) will be available for a full shot-year of LaserNetUS experiments.
The Jupiter Laser Facility (JLF) will resume operations of the Titan and Janus Lasers. The JLF facility at Lawrence Livermore National Laboratory (LLNL) provides 50% of beamtime to LaserNetUS and the other 50% is administered by LLNL through JLF annual call. These beamtime allocations are separate and duplicate proposals are discouraged. The goal of LaserNetUS is to provide complementary opportunities and not meant to replace or duplicate the annual JLF call.
The Institute for the Frontier of Attosecond Science and Technology (iFAST) is will be accepting proposals for LaserNetUS experiments using the iFAST CPA 2.5 micron laser during Cycle 5.
The Diocles 100 TW beamline at the Extreme Light Laboratory (ELL) at the University of Nebraska-Lincoln (UNL) is available for user experiments during Cycle 5; however, the Diocles 0.7 PW beamline is unavailable due to essential maintenance and repairs.
