The Heavy Ion Fu­sion Sci­ence Vir­tu­al Na­tion­al Lab­o­ra­to­ry (HIFS-VNL), a col­lab­o­ra­tion be­tween Lawrence Berke­ley Na­tion­al Lab­o­ra­to­ry (LBNL), Lawrence Liv­er­more Na­tion­al Lab­o­ra­to­ry (LLNL), and Prince­ton Plas­ma Physics Lab­o­ra­to­ry (PPPL), is cur­rent­ly con­struct­ing a new in­duc­tion lin­ear ac­cel­er­a­tor, called Neu­tral­ized Drift Com­pres­sion eX­per­i­ment ND­CX-II. The ac­cel­er­a­tor de­sign makes ef­fec­tive use of ex­ist­ing com­po­nents from LLNL’s de­com­mis­sioned Ad­vanced Test Ac­cel­er­a­tor (ATA), es­pe­cial­ly in­duc­tion cells and Blum­lein volt­age sources that have been trans­ferred to LBNL. We have de­vel­oped an ag­gres­sive ac­cel­er­a­tion “sched­ule” that com­press­es the emit­ted ion pulse from 500 ns to 1 ns in just 15 me­ters. In the nom­i­nal de­sign con­cept, 30 nC of Li+ are ac­cel­er­at­ed to 3.5 MeV and al­lowed to drift-com­press to a peak cur­rent of about 30 A. That beam will be uti­lized for warm dense mat­ter ex­per­i­ments in­ves­ti­gat­ing the in­ter­ac­tion of ion beams with mat­ter at high tem­per­a­ture and pres­sure. Con­struc­tion of the ac­cel­er­a­tor will be com­plete with­in a pe­ri­od of ap­prox­i­mate­ly two and a half years and will pro­vide a world­wide unique op­por­tu­ni­ty for ion-driv­en warm dense mat­ter ex­per­i­ments as well as re­search re­lat­ed to novel beam ma­nip­u­la­tions for heavy ion fu­sion drivers.
