Synchronization and high speed high voltage switcher for pulse bunching system of the cyclotron U-120M

Original language description

Pulse bunching system for neutron time of flight (TOF) measurements on the cyclotron U-120M exploits a unique pulsed vertical deflection of the selected final orbits of the internal accelerated beam of the H− ions to an extractor-stripper. This system is described in details on an individual poster of this conference. A key device is the pulse high voltage (HV) power supply (HV switcher) which is supplying the deflector and elevates H− ions in defined time structure to an extractor-stripper. The developed HV switcher is based on the SiC MOSFET transistors. It can provide HV pulses with the following pulse parameters: amplitude up to 13 kV, front edge less than 20 ns, flat top 20 ns, back edge less than 20 ns and repetition frequency up to several hundred of kHz. We have also developed the pulse synchronization with the cyclotron RF (25 MHz), which enables to set up front edge of bunching pulses within 2π with accuracy 80 ps. Human-machine interface is based on SCADA software Reliance and PLC Tecomat Foxtrot.
