These recommendations can be taken to strengthen our responses to specific grand challenges and to broadly advance the entire scientific frontier of plasma science. CHAPTER 1 RECOMMENDATIONS Stewardship and Advancement of Interdisciplinary Research Finding: Plasma science and engineering (PSE)

From page 386... ...
initiatives would fully exploit the interdisciplinary and multidisciplinary potential of PSE in both fundamental and translational research if properly stewarded. Recommendation: Federal agencies and programs within federal agen cies that are separately focused on fundamental plasma research, and those that are focused on science and technologies that utilize plas mas, should jointly coordinate and support initiatives with new funding opportunities.
|
From page 387... ...
Recommendation: Federal agencies -- for example, DOE, NSF, NASA, and DoD -- should structure funding programs to provide leadership opportuni ties to university researchers in plasma science and engineering areas and to directly stimulate the hiring of university faculty. Finding: Plasma-specific educational and research programs that also provide opportunities to diverse and less advantaged populations are needed to ensure a critically populated PSE workforce.

From page 388... ...
The Research Enterprise in Plasma Science and Engineering Finding: Given these strong international investments, incremental progress in facilities in the United States is insufficient to maintain leadership. Finding: A spectrum of facility scales is required by the subfields of PSE to address their science challenges and translational research.

From page 389... ...
Recommendation: Consistent with our recommendations to broaden the impact of plasma science, the DOE Office of Fusion Energy Science should be renamed to more accurately reflect its broader mission, and so maximize its ability to collaborate with other agencies and to garner nonfusion plasma support. A possible title is Office of Fusion Energy and Plasma Sciences.
|
From page 390... ...
Finding: A widening gap between fundamental studies and application-inspired research impedes progress in both fundamental studies and application inspired research and slows the rate of translational research that leads to societal benefiting technologies. Recommendation: Federal agencies that fund plasma science and engineer ing should forge partnerships with other plasma-focused agencies as well as agencies focused on applications benefiting from plasmas (or programs within agencies)
|
From page 391... ...
Recommendation: NSF, DOE, NASA, and other federal agencies with an in terest and programs in plasma physics should provide regular opportunities for the continued development, upgrading, and operations of experimental facilities for basic plasma science at a spectrum of scales. Finding: Many potential users of these experimental facilities would benefit from small levels of support to gain experience with and obtain initial data for proof-of-concept demonstrations that are usually expected in a full proposal to PBPSE.
|
From page 392... ...
Recommendation: Funding agencies, and in particular DOE and NSF, should support mechanisms for making computational plasma software more wide ly accessible to noncomputing experts, and to transition current codes to new computing architectures. Finding: At the time of this writing, opportunities for machine learning (ML)
|
From page 393... ...
leadership, DOE and other agencies should formulate a national strategy to develop and build new classes of high intensity lasers that enable now inaccessible parameter regimes. Facilities constructed through the strategy above would produce the technologically highest intensities to open up new regimes in high field physics and ion acceleration, having repetition rates at and beyond 1 kHz, with shaped pulses enabling precision control, and with active feedback and machine learning for acceleration and plasma optics.
|
From page 394... ...
Finding: A range of needed computational tools, both fluid-based and DSMC PIC, is also needed for modeling plasma sources. Finding: The innovation that comes from healthy competition would help restore U.S.
|
From page 395... ...
Recommendation: The DOE-NNSA, DOE-FES, and NSF-MPS should increase resources for development of new diagnostics and analysis methodologies to address needs for ongoing innovation in high energy density physics. Recommendation: The current National Nuclear Security Administration (NNSA)

From page 396... ...
Chapter 5: Low-Temperature Plasmas Finding: The success of the DOE Low Temperature Plasma Science Center program underlines that there is a need to sustain LTP research directions for a sufficient period of time (5 to 10 years) and size with support on the level of ~$2 million per year to enable scientific impact and translation of research into society benefiting applications.

From page 397... ...
leadership in LTP in line with the recom mendation in Chapter 1. Recommendation: DOE-FES should establish and coordinate a multi agency Low Temperature Plasma Science Center Program to support multidisciplinary research teams and to establish the scientific basis of emerging application areas of low-temperature plasma science.
|
From page 398... ...
Finding: Continuing initiatives like the DOE Low Temperature Plasma Science Center program will help sustain an internationally competitive LTP commu nity in the United States. Finding: LTP research at U.S.
|
From page 399... ...
Recommendation: NSF and DOE should expand opportunities to devel op and acquire diagnostics, plasma sources, numerical models, and reac tion mechanisms in support of low-temperature plasmas science, perhaps through the NSF/DOE Partnership in Basic Plasma Science.
|
From page 400... ...
Recommendation: DOE-FES should structure funding opportunities in mag netic confinement fusion energy to provide leadership opportunities to uni versity researchers and to directly stimulate the hiring of university faculty.
|
From page 401... ...
Finding: The NUF program and the graduate fellowship could be used as a tool to enhance diversity within the MFE research community. Recommendation: The DOE Office of Science should restore discipline specific graduate fellowships and undergraduate research programs that support magnetic confinement fusion energy (MFE)

, DOE, and other stake-holders (see Table 1, #6 and #24) to develop a collaborative program that enables space and astrophysical plasma scientists to collaborate with laboratory plasma experimentalists and ad vance both fields by leveraging their different needs and knowledge bases.
|
From page 403... ...
To ensure cost and resource efficien cies, NSF and NASA should coordinate further on funding opportunities. Finding: Increased support is needed to meet the challenge of designing and constructing compact plasma and remote-sensing instrumentation suitable for Cubesats and smallsats.
