The prototype's characteristics of the cavity for excitation of parallel coupled RF accelerating structure.

The prototype of the cavity for excitation of the parallel coupled RF structure is per- formed as a segment of conventional rectangular waveguide with short circuit on one side and coupling aperture on the other side. It is loaded by reactive rods to decrease the wave

RF system of Minor Storage ring of Technological Storage ring Complex

The status of the commissioning of the RF system of the minor storage ring for Techno- logical SR source is discussed. This minor storage ring is designed as independent SR source and as injector for major storage ring of the Technological SR source complex. The component parts of RF control system, RF power amplifier 34.52 MHz 5kW and RF cavity are described. Initial results of measurements and tests are presented.

Powerful Precision Current Source IST-1000-100 for Magnetic Systems of accelerators magnetic systems.

This paper describes a precision current source 1000A 100V designed for supplying stor- age ring magnetic systems. This device has the following parameters: - current long-term stability: 0,005%. - output current ripple level no more than 0,01%. The device is con- trolled by PC using CAN interface.
