The Nuclotron Booster in NICA project is aimed to accelerate heavy ions up to 600 MeV/u to provide effective stripping before injection into the Nuclotron. The Booster power supply system consists of one powerful unit, providing maximum current of 12 kA and field ramp up to 1 T/s, and two additional units, that are used for the ring working point adjustment. The quench protection system is based on thyristor keys. Structure and parameters of the power sypply system is presented.

Power supplies which feed magnetic systems of electron linac together with the control system are very critical parts of any linac. The quality of power supplies and control software defines safety of the accelerator operation, stability and cost of operation. One of the today’s tendencies in power supply system architecture is to use distributed CAN-connected power supplies with high level of local intellectual properties. These properties allow to achieve high stability, high safety of operation together with the specific features such as coil temperature check without any temperature sensors. Such programmable power supplies with the intellectual CANopen controller have been designed for the specific accelerator applications. The control system software was adapted to operate with CANopen protocol. Marathon's IPP-1/100 & IPP-4/35 power supplies with CANopen* are used now within the control systems of LU-60m and LU-10 linacs. 3200 hours of continues operation were achieved since the year 2008.

This report presents three types of direct current supplies that have been developed at BINP SB RAS. Their maximum current values are ±20А with output voltage up to ±50V, ±100V, ±150V. The power supplies are intended for steering electromagnets of colliders and storage rings, operating as the Synchrotron Radiation sources. The power supply channel occupies a 3U subunit crate (432*355*133mm) of the "Euromechanics" standard. Specialized units are used to control and monitor the power supplies through the CAN-bus interface. The output current accuracy is of the order of 100ppm for 10 hours of operation. This report presents experimental characteristics of the power supplies.

A facility for measurement of critical current and minimal quench energy of Rutherford-type superconducting cables for accelerator magnets is created. The sample current is energized by a superconducting transformer circuit using an inductive method, where the sample conductor is a part of the secondary circuit. Two superconducting transformers were built; one of them is a solenoid type coil. The transformer consists of two concentric solenoids; the secondary coil is placed inside the primary coil. External magnetic field up to 6.5 T is provided by a superconducting solenoid with the aperture diameter of 60 mm. The second superconducting transformer with race-track coils has been designed and taken into operation. Short-circuited sample, fixed on a special holder, is placed in the aperture of a superconducting dipole magnet such way that the plane of sample loop is perpendicular to direction of external magnetic field, which can reach up to 6 T. The critical current of the secondary superconducting coil is 18 kA. The equipment for measurements of characteristics superconducting cable versus magnetic field is described.

The presented report contains the description of high-voltage source with output voltage up to 60kV and output current up to 1A. The source consist of the chopper with IGBT switches working with a principle of pulse-width modulation and the H-bridge converter with IGBT switches, both working on programmed from 15 to 25 kHz frequency, and the high voltage sectioned transformer with the rectifier and additional capacity filter. The transformer is made in oil tank with silicon oil. The additional capacity filter provides low ripple and noise level in working range of output currents. A nominal output voltage of the source is 60kV, maximal voltage is 80kV. The source can operate in normal mode with series of high-voltage breakdown in output voltage. In the high-voltage breakdown the released in load and matching circuit energy is less than 15 J at maximum operating voltage 65kV. The efficiency of system is more than 80% at the nominally output power 60kW. The controller of the source is developed with DSP and PLM, which allows optimizing operations of the source. For control of the source serial CAN-interface is used. The description of the source and the test results are presented.

A compact accelerator UEL-10-D for radiographic inspection of steel products up to 500mm thick has been designed and manufactured. The accelerator provides the 10 MeV energy and the photon dose rate 1m from target of 30Gy/min. The accelerator consists of an irradiator mounted on a yoke, heat-exchanger and industrial panel computer. The equipment of the accelerator is mostly located inside the irradiator including the HV power supply system, magnetron modulator and control system blocks. Using this yoke, the irradiator is installed on a bridge crane, which ensures its high manoerability necessary to test products of complicated geometry. Size of the irradiator without yoke is 2040*950*950 mm. In 2010, the accelerator was put into operation at the "Izhorskie Zavody", St. Petersburg. The UEL-10-D accelerator can be also used in radioscopic or tomographic systems.

Physical project of neutron sources for the neutron therapy and neutron activation analysis is proposed. The neutron sources are based on beam provided by the high-current deuteron accelerator. Neutron sources produces 14 MeV fast neutrons with intensity up to 5*1012 n/s using T(D,n)4He threshold reaction at the energy of deuteron beam about 400 keV and average current up to 20 mA. Neutron source can be makes for neutron capture therapy (NCT) by using of moderator system consisted of the tungsten converter, bismuth reflector, graphite and polyethylene. Liquid-crystalline DNA-Gd nanoparticles, as a potential biomaterial for NCT were investigated on the thermal neutron beam.
