Status of the Laser Ion Source Upgrade (LION2) at BNL

A laser ion source (LION) at Brookhaven National Labor-atory (BNL) has been operational since 2014 to provide low charge state heavy ions of various species for Rela-tivistic Heavy Ion Collider (RHIC) and NASA Space Radiation Laboratory (NSRL). Pulsed ion beams (100~300 µs) with beam current ranging from 100 µA to 1 mA from any solid-state targets can be supplied without memory effect of previous beams at pulse-by-pulse basis. LION is an essential device for the operation of a galactic cosmic ray simulator at NSRL together with high-performance beams for RHIC. Because the importance of LION has been widely recognized, an upgraded version of LION, which is called LION2, is being developed for improved performance and reliability. The design and status of the LION2 will be shown.
