Acceleration the Beams of He⁺ and Fe14+ Ions by HILAC and Its Injection into NICA Booster in Its Second Run

Injector of NICA accelerating facility based on the Heavy Ion Linear Accelerator (HILAC) is aimed to inject the heavy ions having atomic number A≈200 and ratio A/Z ≤ 6.25 produced by ESIS ion source accelerated up to the 3.2 MeV for the injection into superconducting synchrotron (SC) Booster. The project output energy of HILAC was verified on commissioning in 2018 using the beams of carbon ions produced with the Laser Ion Source and having ratio A/Z=6 that is close to the project one. Beams of He1+ ions were injected into Booster in its first run and accelerated in 2020. In 2021 ions of Fe14+ produced with the LIS were injected and accelerated up to 200 MeV/u. Beam formation of Fe ions and perspectives of using LIS for the production the ions with high atomic mass A and ratio A/Z matching to HILAC input parameters are described. HEAVY ION LINEAR INJECTOR Heavy ion injector of the NICA project is based on the heavy ion linear accelerator (HILAC) and aimed to be injector of gold ions into SC Booster synchrotron of the NICA facility. The main features of it are presented in the Table 1. Table 1: Main Features of HILAC
