NICA is a new accelerator complex being under design and construction at Joint Institute for Nuclear Research in Dubna. The actual design and the main characteristics of superconducting magnets for the NICA booster and the NICA collider are given. The magnets are based on a cold window frame iron yoke and a single-layered superconducting winding made from a hollow NbTi composite superconductor cable cooled with forced two-phase helium flow. The first results of cryogenic tests of the magnets for the NICA project are presented.

The electron cooling system at electron energy up to 2.5 MeV for the NICA collider is under design at JINR. The magnetic system and system of transfer of capacity on high potential is developed. The high voltage generator prototype on 250 kV was tested. The technical design of the electron cooling system was started.

Diagnostic technique applied for FEL ultrashort electron bunches is developed at JINR-DESY collaboration within the framework of the FLASH and XFEL projects. Photon diagnostics developed at JINR-DESY collaboration for ultrashort electron bunches are based on calorimetric measurements and detection of undulator radiation. The infrared undulator constructed at JINR and installed at FLASH is used for longitudinal bunch shape measurements and for two-color lasing provided by the FIR and VUV undulators. The pump probe experiments with VUV and FIR undulators provide the bunch profile measurements with resolution of several femtosecond. The MCP based radiation detectors are effectively used at FLASH for VUV pulse energy measurements. The new three MCP detectors operated in X-ray range are under development now in JINR for SASE1-SASE 3 XFEL.
