Laser ion source in injection facility of NICA project

In the framework of the NICA project for the development of an accelerator collider facility at the LHEP JINR, Dubna, the design and commissioning of two injectors are under way. The Heavy Ion Linear accelerator (HILAC) is intended to inject the gold ions into the superconducting synchrotron Booster and designed to accelerate particles with a charge-mass ratio Z/A ≥ 0.16 up to an energy of 3.2 MeV u−1. HILAC in 2015 installed in the workplace in the hall of the injection facility. In 2018, a series of tests on HILAC commissioning had been done to measure the energy and estimate transmission of accelerated beams of the carbon ions from the laser ion source. The Light Ion Linear accelerator (LILAC) is intended for injection into the superconducting synchrotron Nuclotron the polarized deuterons and protons, as well as the light ions from LIS and is in the design stage for accelerating particles with a charge-mass ratio of Z/A ≥ 0.33 to 7 MeV/u. The stable beam intensity from LIS is strongly desirable for the tasks listed above. The article describes the use of the beams from a laser ion source based on an Nd:YAG laser in the injection facility and presents a method for solving the problem of beam instability due to uncontrolled emission caused by reflected radiation.
