Abstract
Heavy Ion Linear Accelerator (HILAC) is designed to accelerate the heavy ions with ratio A/Z=6.25 produced by ESIS ion source up to the 3.2 MeV for the injection into superconducting synchrotron (SC) Booster. HILAC was commissioned in 2018 using the carbon beams from Laser Ion Source (LIS). The project output energy was verified. Transmission could be estimated only for DTL structure because of the presence at the RFQ input the mixture of ions with different charge states extracted from laser-plasma. To estimate transmission through the whole linac the ion source producing the only species He⁺ was designed. The beams of He⁺ ions were used for the first run of SC Booster. The design of the helium ion source and results of the He⁺ beam acceleration and injection are described.
