This modulator was design for tunnel installation. The modulator consist from two oil-filled tanks, the first is for two klystrons and the second for pulse transformer. The pulse trans- former consist from 42 core made from Finmet3 material, each core is drive by voltage
kV by two IGBT plates in parallel, one of them has core reset circuits. The total num- ber of IGBT plates is 84. Each core has one turn at primary and transformer has four turns for secondary. This modulator can drive: short up to 1.6 microsecond, high voltage up to 500 kV pulse with current up to 540 A for two X-band 75 MW klystrons. The pulse top flatness is 2%. The expected modulator efficiency is about 75%. The step one of the modulator test was done in the summer of 2005, 300 kV of output voltage and full current at 1 pps was achieved.

Bidirectional Precision Current Source for Superconducting Solenoids.
This paper describes a precision bidirectional current source VCH-300-10 designed for supplying superconducting solenoids. This device has the following parameters: - output current -300 0 +300A, - output voltage -10 0 +10V, - current long-term stability 0,005%, - power grid harmonics ripple level no more than 10mV. This device has both manual and PS control. PS control uses RS-232 and USB interfaces.
