Overview of virtual national laboratory objectives, plans, and projects

“…is proposed, which would be an intermediate step between present experiments and a much larger Integrated Research Experiment~IRE; see Barnard et al, 2002!. The IRE would validate prototype driver technology with multiple beams.…”

“…comm.!. Well-understood simulations confirmed by experiments will allow analytic models~e.g., see Kaganovich et al, 2002, on neutralization! to be developed and inserted into a systems code used to optimize the design of HIF drivers and future experiments in an integrated fashion, taking into account injection, acceleration, drift compression, final focus, and chamber propagation.…”

Direct–indirect mixed implosion mode in heavy ion inertial fusion

“…In heavy ion beam (HIB) inertial confinement fusion (ICF), the following critically important issues have been intensively studied: in source, accelerator physics for high current beam, beam bunching, HIB transport in a reactor, HIB target interaction, stopping power, high-energy density matter physics by HIB, and so on [1][2][3][4][5][6][7][8][9][10]. In fuel target implosion, ICF has two ways of implosion schemes, which are indirect-driven [3,4,11,12] scheme and directdriven [13,14] implosion scheme.…”

Analytical solutions for the nonlinear longitudinal drift compression (expansion) of intense charged particle beams

“…In general, a complete description of collective processes in intense charged particle beams is provided by the nonlinear Vlasov-Maxwell equations [1] for the self-consistent evolution of the beam distribution function, f b (x, p, t), and the self-generated electric and magnetic fields, E(x, t) and B(x, t). While considerable progress has been made in analytical and numerical simulation studies of intense beam propagation [6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,…”
