The new accelerator complex Nuclotron-based Ion Collider fAcility (NICA) is now under development and construction at JINR, Dubna. This complex is assumed to operate using two injectors: modernized old Alvarez-type linac LU-20 as injector of light polarized ions and a new Heavy Ion Linear Accelerator HILAc - injector of heavy ions beams. The new heavy ion linac accelerate ions with q/A values above 0.16 to 3.2 MeV/u is under commissioning. The main components are 4-Rod-RFQ and two IH - drift tube cavities is operated at 100.6 MHz. Main results of the HILAc commissioning with carbon beam from the laser ion source are discussed.

The future experimental program of super heavy element synthesis at GSI desires high intense heavy ion beams at or above the coulomb barrier, exceeding the capabilities of the GSI-UNILAC (Universal Linear Accelerator). Additionally, the existing GSI accelerator chain will be used as an injector for FAIR (Facility for Antiproton and Ion Research) primarily providing high power heavy ion beams at a low repetition rate. Due to this limitations a new dedicated superconducting (sc) continuous wave (cw) linac is proposed to keep the Super Heavy Element (SHE) research program at GSI competitive. The construction of the first linac section has been finished in the 3rd quarter of 2016. It serves as a prototype to demonstrate its reliable operability in a realistic accelerator environment. This demonstrator cryomodule comprises the sc 217 MHz crossbar-H-mode (CH) multigap cavity as the key component of the whole project and two sc 9.3 T solenoids. The performance of the cavity has been extensively tested at cryogenic temperatures. In this contribution the measurement results of initial cold tests will be presented.
