The project of new accelerator complex NICA relating to nuclear and hadron physics require a more powerful longitudinal and transverse cooling that stimulates searching new technical solutions. The new accelerator complex NICA is designed at the Joint Institute for Nuclear Research (JINR, Dubna, Russia) to do experiment with ion-ion and ion-proton collision in the energy range 1-4.5 GeV/u for studying the properties of dense baryonic matter at extreme values of temperature and density with planned luminosity 10²⁷ cm⁻²s⁻¹. This value can be obtained with help of very short bunches with small transverse size. This beam quality can be realized with help of stochastic and electron cooling at energy of the physics experiment. The electron cooling system on 2.5 MeV consists of two coolers, which cool both ion beams simultaneously. The Budker Institute of Nuclear Physics (BINP SB RAS) has already built and commissioned the electron cooling system for the NICA booster, and now it develops the high voltage electron cooling system for the collider. The article describes the construction and status of the cooler development., Proceedings of the 12th International Particle Accelerator Conference, IPAC2021, Campinas, SP, Brazil

The high voltage electron cooling system for the NICA collider is now under development in the Budker Institute of Nuclear Physics (Russia). The aim of the cooler is to increase ion beams intencity during accumulation and to decrease both longitudinal and transverse emmitances of colliding beams during experiment in order to increase luminosity. Status of its development and results of tests of the cooler elements are described in the article., Proceedings of the 27th Russian Particle Accelerator Conference, RuPAC2021, Alushta, Russia

Beam cooling plays a key role in the project of the NICA collider. In order to achieve needed luminosity it is important to provide effective cooling during beam accumulation and during experiment. For this purpose, the ring will be equipped with both electron and stochastic cooling systems.

The project of the control system of linear induction accelerator LIA-20 for radiography is presented in this paper. The accelerator is a complex pulsed machine designed to provide a series of three consecutive electron pulses with an energy up to 20 MeV, current 2 kA and lateral beam size less then 1 mm. To allow reliable operation of the whole complex, coordinated functioning of more then 700 devices must be guaranteed in time frames from milliseconds to several nanoseconds. Total number of control channels exceeds 6000. The control system is based on a variety of specially developed VME and CAN modules and crates. Tango program infrastructure is used. The first stage of commissioning will take place in the end of 2017 and will include launching 5 MeV version of the accelerator., Proceedings of the 16th Int.
