Simulation of 10 A Electron Beam Formation and Collection for a High Current EBIS

Development of an Electron Beam Ion Source (EBIS) for the Relativistic Heavy Ion Collider (RHIC) at BNL requires operating with a 10 A electron beam, which is approximately an order of magnitude higher current than in any existing EBIS device. A test stand is presently being designed and constructed where EBIS components will be twisted. It will be reported in a separate paper at this Conference. The design of the 10 A electron gun, drift tubes and electron collector requires extensive computer simulations. Calculations have been performed at Novosibirsk and BNL using two different programs, SAM and EGUN. Results of these simulations will be presented

RESULTS OF LIA-2 OPERATION

Abstract Recent results of LIA-2 operation are presented. High quality of intense electron beam has been achived in design intervals of energy and current. All key elements of accelerator based on domestic technology successfully passed through long term operational tests
