Introduction
Background for a non-expert reader
RequiredWrite for a non-expert: the topical area, why it matters scientifically and its potential societal impact, the current state of knowledge, and the significant gaps or open questions. Number references in order of appearance, as [1], [4-7].
Written scientific or technical response · Up to 2000 characters
Scientific case
The most detailed section. Reviewers come from a related research area rather than your own, so reference it thoroughly enough for them to judge the work in the context of its topical area.
Objectives, and the measurements that test them
RequiredThe objectives: the hypothesis or essential question, the experimental observables and how they address it, how the experiment was designed from theory, simulations or previous work, and which measurements make it a success. Include the roadmap for analysis and interpretation.
Written scientific or technical response · Up to 5000 characters
Figure for the scientific case
OptionalOne figure is recommended.

Experimental details
Enough for the facility scientists to judge technical feasibility. Fine detail is requested later, from short-listed and awarded experiments, so it does not belong here. Talk to the facility point of contact before you submit: they can flag integration problems early. The committee ranks your proposal against the primary beamline you request, and looks at the secondary one only if the primary is not competitive.
Beamlines, set-up and procedure
RequiredThe primary and the secondary beamline you request, why this facility is essential - the unique capabilities, instrumentation, expertise or partnerships that enable this work - and the experimental set-up or procedure.

Feasibility
Before you fill in the schedule and the amount of support, talk to the facility point of contact about how many days or shifts your experiment needs.
Set-up, parameters, samples and risks
RequiredThe setup and geometry; the laser parameters that are absolutely required and the ones that are flexible; the targets and samples, with any non-standard preparation; whether the setup exists or is new; additional resources needed; and the known risks to a successful experiment.
Written scientific or technical response · Up to 2000 characters
Setup schematic
RequiredKey equipment, laser beam paths, and critical diagnostic placements.

Broader impact
Training people and widening the community around high-power lasers are core missions of the facility, and the committee weighs this section alongside the science. A few clear words per question are enough.
Training, audience and community
RequiredTraining students and early-career researchers is what earns the reduced academic or government rate, so say what training this work provides and whether the results are thesis work; the audience and venue for them; how the work sustains community interest and engages underrepresented groups.

Team narrative
The team itself is the roster below. This is the one or two paragraphs about the people who make the experiment work.
The key people, one to three sentences each
RequiredFor the key people - the lead PI, whoever fields the primary diagnostics, whoever supervises - one to three sentences each: their role and tasks, where the necessary experience came from, and what training or assistance they need from facility staff.

How review works
What reviewers assess
Your proposal is assessed for scientific merit, training, equity, diversity and inclusion, and interdisciplinarity.
From review to decision
Assigned reviewers assess your proposal and provide written feedback. ALLS considers the reviews and decides which proposals receive access. Your outcome becomes available when ALLS releases the decisions.
Decision timing and questions
Contact [email protected] for the decision timeline or help choosing an instrument.
Questions about this call or the instruments go to Advanced Laser Light Source (ALLS) directly.
