The regimes of high intensity beam of 197Au⁷⁹⁺ ions in NICA Collider is considered. The first stage – ion storage is proposed to be performed with Barrier Bucket technique at ion energy of 1–3 GeV/u. Experiments in collider mode in this energy range can be performed at injection energy. For experiments at higher, up to 4.5 GeV/u, energy ions are accelerated with the same BB method. Formation of bunched beam is fulfilled in two steps – first, at 24th harmonics and then, final formation, at 72th harmonics of RF system. The possibility of achievement of designed bunch parameters is shown.

The free electron laser (FEL) facility at Budker INP is being developed for more than 15 years. It is based on the normal conducting CW energy recovery linac (ERL) with rather complicated magnetic system lattice. Up to now it is the only one in the world multiorbit ERL. It can operate in three different regimes providing electron beam for three different FELs. Its commissioning was naturally divided in three stages. The first stage ERL includes only one orbit placed in vertical plane. It serves as electron beam source for terahertz FEL which started working for users in 2003. Radiation of this FEL is used by several groups of scientists including biologists, chemists and physicists. Its high peak and average powers are utilized in experiments on material ablation and biological objects modification. The second stage ERL is composed of two orbits located in horizontal plane. The second stage FEL is installed on the bypass of the second orbit. The first lasing of this FEL was achieved in 2009. The last stage ERL will include four orbits. Its commissioning is in progress now. In this paper we report the latest results obtained from the operating FELs as well as our progress with the commissioning of the two remaining ERL beamlines. We also discuss possible options for the future upgrade.

A new electron source for the Race-Track Microtron Recuperator is being developed by BINP SB RAS. It will increase average beam current and brightness of synchrotron radiation. Instead of the static 300kV electron gun operated now we are developing RF gun with the same energy of electrons. This RF gun consists of RF cavity with a gridded thermo cathode mounted on the back wall. RF cavity is driven by a 60 kW generator with last stage equipped by GU101A tetrode tube. Operational frequency of the cavity is 90.2 MHz. It is equal to the second subharmonic of the Microtron RF system frequency. A set of low power electronics controls amplitude of the cavity voltage and its tuner. This system, including a diagnostics beam line, has been installed to serve as a test bench to test the RF cavity and for beam dynamics studies. In continuous regime the designed 300 kV voltages at the acceleration gap is obtained. This paper summarizes the first test results of the cavity in this configuration.
