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.

The NICA accelerator complex in JINR consist of two linear injector chains, a 578 MeV/u superconducting (SC) Booster synchrotron, the existing SC synchrotron Nuclotron, and a new SC collider that has two storage rings. The construction of the facility is based on the Nuclotron technology of SC magnets with an iron yoke and hollow SC cable. Assembly of the Booster synchrotron was finished in autumn of 2020 and first machine Run and experiments with ion beams were successfully done in December 2020. The results of this Run are discussed in this paper.

Stochastic cooling is one of the crucial NICA (Nuclotron-based Ion Collider fAcility) subsystems. This system requires fine tuning of the response delay to the kicker, for both longitudinal and transverse stochastic cooling systems. The use of a digital delay line allows to add additional features such as a frequency dependent group velocity correction. To analyse the capabilities of the digital delay unit, a prototype of the device was created and tested. The article presents the characteristics of the prototype, its architecture and principle of operation, test results and estimations for the future developments.
