	The SC program at IHEP of NRC Â“Kurchatov InstituteÂ” has been developed intensively in the 1980ies in the framework of the UNK project. More than a hundred of models of the SC magnets of various designs, and then the pilot batch consisting of 25 full-scale dipoles and 4 quadrupoles have been designed, manufactured and tested at IHEP. Two SC magnetic systems of Electron Lens for the Tevatron collider were developed, manufactured, shipped and successfully brought into operation. Development of fast-cycling SC magnets for the FAIR project is discussed. Racetrack coils from HTS-2G tape for electrical machines that were developed, manufactured and tested are reported. Test and trial results with HTS dipole magnets employing Bi2223 as well as second-generation HTS are also reviewed.

TUPSA061	Comparative Research of Low Energy Beam Transport Systems for H-minus Ion Beam	ion, emittance, simulation, quadrupole	333
	B.A. Frolov IHEP, Moscow Region, Russia V.S. Klenov RAS/INR, Moscow, Russia
	The source of H-minus ions for the injection in LU-30 accelerator is being constructed at IHEP. A three-dimensional (3D)simulation code IBSimu has been utilized for modeling of the transport and matching system of beam from the H-minus ion source into RFQ. A magnetic low energy beam transport (LEBT) line consisting of two solenoids and LEBT consisting of six magnetic quadrupole lenses were analyzed. The particle data from the 50 mA 100 keV ion beam extraction system simulations were taken as the starting data for the LEBT simulations. The main objective of the project was to achieve the required Twiss parameters and to minimize emittance growth at RFQ entrance. The LEBT consisting of two solenoids is more convenient in adjustment and as simulation results have shown this system offers more acceptable beam characteristics at the match point in comparison with LEBT composed of quadrupole lenses.

	The Helmholtz Institut Mainz (HIM) performs experiments related to possible improvements of high-energy d.c.-electron coolers. Results and activities concerning non-invasive beam diagnostics and beam control at large operating currents will be shown. Furthermore, progress of our project to use turbo generators as a means for potential-free power generation in high-energy electron coolers is presented.

	OCEM and ENEA gained a wide experience in the design and experimental characterization of fast and accurate switching systems for high DC currents, as required to supply magnets and superconductors. The exploited idea consists in inserting an electronic switch in parallel to a light electromechanical switch in air to combine the benefits of both devices. The electronic switch is turned on and off to support the electromechanical commutations limiting their jitter and the arcs that would reduce the system lifetime. During the already performed tests, DC currents up to 20 kA were diverted in less than 100 mks with good repeatability. In case of emergency, the current can be interrupted in few tens of milliseconds. A resistor can be inserted in parallel to the switch to discharge inductive loads or to produce desired overvoltages (a voltage up to 5 kV was reached in this configuration). Specific circuits were designed to preserve the components from transient voltage overshoots. This switching system is expected to work for 10000 operations without major maintenance. The developed solutions may be extended to many relevant applications as particle accelerators and HVDC networks.
