IFE chamber dry wall materials response to pulsed X-rays and ions at power-plant level fluences

Laser inertial fusion dry-wall materials response to pulsed ions at power-plant level fluences

“…The work reported here is a continuation of experiments previously detailed [1]. In the earlier study, the roughening threshold for powder metallurgy (PM) W was measured at 1.25 J/cm 2 using the RHEPP-1 N beam.…”

“…Both Z and RHEPP-1 are located at Sandia National Laboratories. Materials exposure results on Z are discussed elsewhere [1]. We report here on repeated exposure of first-wall armor materials to intense ion beams.…”

Aerosol formation and hydrogen co-deposition by colliding ablation plasma plumes of lithium and lead

“…Hydrogen retention in Li-Pb-H, Pb-Pb-H and Li-Li-H codeposits has been evaluated, time-integrating the partial pressures of hydrogen-containing gases in Eqs. (1)- (3). Results are shown in Fig.…”

“…(CoA) region. The laser power density is varied between 2 and 10 J/cm 2 /pulse, relevant to the inertial fusion reactor situation [3].…”

“…Along with pellet implosions, the interior of target chamber is repeatedly exposed to intense pulses of DT-fusion neutrons, X-rays, unburned fuel particles, He-ash and pellet debris, perhaps in the form of C x H y , the total power of which amounts to the order of 10 J/cm 2 /pulse [3]. As a result, wall materials will be subjected to ablation, ejecting particles mostly in the plasma state.…”
