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.

WEPOTK020	Slanted Beam Extraction on Laser Ion Source	2090

	Funding: US DOE, Office of Science, under contract DE-SC0012704. Laser ion sources generate plasma and supply ions by focusing energy by light onto a solid surface. The ionization is achieved during the pulsed laser irradiation period. Then the plasma expands vertically from the target surface as it moves forward. Usually, this drift distance is chosen from tens of centimeters to several meters. Once the required pulse width and plasma density are met, an extraction electric field is applied. In most cases, this electric field is set in the same direction as the direction of the plasma. In this study, we experimentally verify how performance is achieved when the direction of the extraction field is at an angle to the direction of motion of the plasma. If the extraction field can be slanted without degradation of the ion source performance, it is considered to be able to shield neutral vapors and debris generated simultaneously with the plasma, which will be advantageous for the long-term operation of the laser ion source.
