布鲁克海文国家实验室为相对论重离子对撞机（RHIC）和美国航空航天局空间辐射实验室开发了新的预注入系统、电子束离子源（EBIS）。主离子供应站的设计是一个关键问题，因为它需要同时向多个用户提供不同离子种类的光束。散焦激光离子源可以提供低电荷态和低发射度的离子束，是RHIC-EBIS的首选离子源。采用合适的漂移长度和螺线管设计，可以在较长的脉冲长度下保持足够的总电荷数。介绍了一次离子源的整体设计、光学器件的布置、固体靶的结构和靶的加热。
Brookhaven National Laboratory has developed the new preinjector system, electron beam ion source (EBIS) for relativistic heavy ion collider (RHIC) and National Aeronautics and Space Administration Space Radiation Laboratory. Design of primary ion provider is an essential problem since it is required to supply beams with different ion species to multiple users simultaneously. The laser ion source with a defocused laser can provide a low charge state and low emittance ion beam, and is a candidate for the primary ion source for RHIC-EBIS. We show a suitable design with appropriate drift length and solenoid, which helps to keep sufficient total charge number with longer pulse length. The whole design of primary ion source, as well as optics arrangement, solid targets configuration and heating about target, is presented.
