NIF Discovery Science: Proposal submission and review process

Facility review and feedback to proposers is a key part of ensuring feasibility of experiments

• Shot days scheduled by quarter over a 2 year execution period

• Shots planned in detail and scheduled as part of semi-annual schedule process for NIF

• Periodic meetings with each team to facilitate planning and early identification of issues or constraints

• These ongoing interactions are necessary to manage the integration — The Discovery Science campaigns are

typically very different than routine programmatic experiments

— There are often changes each shot day as teams modify plans to respond to what they are learning

NIF management and collaborators coordinate scheduling and stay in close contact with users throughout the experiment planning phase

JLF uses a proposal submission process to select experiments

• Experiments are 4-week campaigns. 85% of experiments have been collaborative (both LLNL and non-LLNL researchers) no matter the institution of the PI.

• 8-9 experiments in each target area each year

• Annual proposal submission. Proposals ranked by a committee of LLNL and university panel members.

• Ranked by scientific and/or programmatic merit and impact• Assessed for feasibility• Consideration given for inclusion of students and young researchers• Starting this year, one experiment is at the discretion of the new LLNL HED

Center, and one Titan run is reserved for LaserNetUS• At least one team new to JLF will be accepted each year, even if the proposal is

judged slightly weaker than others

• About half of the proposals submitted have been accepted over the past 5 years• Janus (long pulse): 38/60 proposals • Titan (short pulse): 38/75 proposals

One week between campaigns for tear-down, set-up, and maintenance

Usually shoot Monday-Thursday and alternate Fridays— We do what we can to make up for lost shots

Campaigns average ∼ 1 week of shot days to start collecting meaningful data

Typical shot day:— 0600-1900: nominal user access— 0500-0730: system warmup and alignment to target areas— 0830: plan-of-the-day meeting— 0900: first shot— 1830: last shot, system shutdown

A good day will currently yield 8-10 shots to a target area

The four-week campaigns consist of 16-18 shot days
