The Workshop will aim to address the following questions (the "charge" of the Workshop):
- What are the science questions that require establishment and operation of plasma science user facilities, and cannot be addressed on smaller scale single-PI experimental facilities? Are there compelling plasma science questions of such value and interest to the global scientific community that may warrant construction and operation of a new major NSF user facility? If so, what are they?
- Under constrained resources, what are the upsides and the downsides of investing in the operation of user facilities in each of the relevant sub-fields?
- What may be the limiting factors, e.g., the size of the community of potential users or the flexibility and ease of operation, in establishing an experimental facility as a user facility?
- Are there particular challenges to transparent operation of user facilities specific to plasma science or any of its sub-fields? If so, what are they and what strategies or modes of operation may be used to overcome such challenges?
- What are best practices for managing transparent and efficient operation of a plasma science user facility for mid-scale and major user facilities?
- Identify and discuss compelling topics in plasma physics that require facilities larger than typically operated by single-PI groups.
- Discuss lessons learned from the operation of open user facilities, collaborative facilities, user networks, and larger single/few PI facilities in the plasma physics and related scientific communities. Extract from the discussion guidance to be offered to potential future facilities, NSF, and other agencies regarding what works well.
- Discuss advantages and disadvantages for investments in user facilities under constrained resources.
Workshop format (2 days):
- First day: Presentations on science topics, moderated discussions, breakout sessions
- Second day: Presentations on facilities' experiences and best practices, moderated discussions, breakout sessions, recap from science areas
Topic areas and participants:
1. Quantum properties of dense plasmas
2. Plasma in super-critical fields
3. Single component plasmas, dusty plasmas, and matter-antimatter plasmas
4. Laboratory astrophysics
5. Relativistic laser and beam plasma interactions
6. Coherent structures and energy dissipation in plasmas
7. Controlled production of chemical reactivity
How and under what conditions do quantum properties such as spin and band structure control the behavior of dense plasmas? How and under what conditions are quantum effects and strong coupling effects linked? To study these questions, does one need physical conditions that can only be supplied by a major facility such as a big laser? Will the answers be sufficiently universal for broad application to planetary science, astrophysics, and earthbound applications in laser- and particle beam-driven fusion, or more everyday processes such as laser welding/machining and high current switches?

How can we study the physics of electromagnetic fields that exceed the QED-critical field strength and its effect on plasma in a laboratory setting? What are the important physical effects at such field strengths and do we have the theoretical tools to describe them properly? How will advancements in this field affect our understanding of astrophysics and future experiments at high energy-densities?

What unique photon and particle beams can such interactions produce? Can such interactions be used to produce unique plasmas? Can such interactions be used to control the six dimensional phase space of ultra- bright particle beams?
