Book Description
Results are presented from a preliminary scoping study of an ohmically-heated reversed-field pinch (RFP) operating with a steady-state DT fusion neutron wall loading in the range of 1 to 5 MW/m2 while generating less than 100 MW total fusion power. These results are also useful in projecting the development of ignition/burn RFPs, as well as offering an economic source of DT neutrons for fusion nuclear testing. 14 refs.

Book Description
The conceptual design of an ohmically heated, reversed-field pinch (RFP) operating at (approximately)5-MW/m2 steady-state DT fusion neutron wall loading and /approximately/124-MW total fusion power is presented. These results are useful in projecting the development of a cost effective, low input power (/approximately/206 MW) source of DT neutrons for large-volume (/approximately/10 m3), high-fluence (3.4 MW yr/m2) fusion nuclear materials and technology testing. 19 refs., 15 figs., 9 tabs.

Book Description
The dense Z-pinch (DZP) is one of the earliest and simplest plasma heating and confinement schemes. Recent experimental advances based on plasma initiation from hair-like (10s .mu.m in radius) solid hydrogen filaments have so far not encountered the usually devastating MHD instabilities that plagued early DZP experiments. These encouraging results along with debt of a number of proof-of principle, high-current (1--2 MA in 10--100 ns) experiments have prompted consideration of the DZP as a pulsed source of DT fusion neutrons of sufficient strength (/dot S//sub N/ greater than or equal to 1019 n/s) to provide uncollided neutron fluxes in excess of I/sub .omega./ = 5--10 MW/m2 over test volumes of 10--30 litre or greater. While this neutron source would be pulsed (100s ns pulse widths, 10--100 Hz pulse rate), giving flux time compressions in the range 105−−1°sup 6/, its simplicity, near-time feasibility, low cost, high-Q operation, and relevance to fusion systems that may provide a pulsed commercial end-product (e.g., inertial confinement or the DZP itself) together create the impetus for preliminary considerations as a neutron source for fusion nuclear technology and materials testings. The results of a preliminary parametric systems study (focusing primarily on physics issues), conceptual design, and cost versus performance analyses are presented. The DZP promises an expensive and efficient means to provide pulsed DT neutrons at an average rate in excess of 1019 n/s, with neutron currents I/sub .omega./ /approx lt/ 10 MW/m2 over volumes V/sub exp/ greater than or equal to 30 litre using single-pulse technologies that differ little from those being used in present-day experiments. 34 refs., 17 figs., 6 tabs.

Book Description
Plasma Science and Engineering transforms fundamental scientific research into powerful societal applications, from materials processing and healthcare to forecasting space weather. Plasma Science: Enabling Technology, Sustainability, Security and Exploration discusses the importance of plasma research, identifies important grand challenges for the next decade, and makes recommendations on funding and workforce. This publication will help federal agencies, policymakers, and academic leadership understand the importance of plasma research and make informed decisions about plasma science funding, workforce, and research directions.
