AB  - To investigate chiral magnetic effect, 96Zr and 96Ru beams have been accelerated at relativistic heavy ion collider (RHIC) in Run18 at Brookhaven National Laboratory (BNL). 96Zr and 96Ru beams were provided from electron beam ion source (EBIS) injector and tandem Van de Graaff, repectively. In the presentation, 96zr beam production and acceleration will be reported. The EBIS injector consist of laser ion source, EBIS as a charge breeder, 300 keV/u RFQ and 2 MeV/u IH-DTL. The natural abundance of 96Zr is only 2.8 % and about 50 % is occupied by 90Zr. To obtain sufficient beam current, mass number 96 enriched material was used. Unfortunately, only available form of the enriched material is oxide powder which does not suit for laser ion source target. We have established sintering technique of ZrO2 powder to make a solid piece which can be installed into the laser ion source. The induced singly charged Zr and oxygen were delivered to the EBIS to be ionized further. We have optimized laser irradiation condition, EBIS confinement time, operating condition of the linacs to maximized the performance of the linac based injector. The detailed R&D works will be presented in the conference.
