In 2007 Continental Electronics delivered to Brookhaven National Laboratory (BNL) an Integrated 2MW Klystron Transmitter and 100 kV High-Voltage Power Supply (HVPS).  The system was designed and manufactured by Continental Electronics under a competitive contract from BNL.

 

The Transmitter and HVPS system are designed to accommodate a 2 MW klystron operating at 704 MHz.  The equipment is planned as part of an experiment at BNL for  perhaps several years, after which time it is intended to be installed as an improvement to the Relativistic Heavy Ion Collider (RHIC) facility.

 

The HVPS is based on Continental Electronics’ Crowbar-less IGBT High-Voltage Switching supply design and provides up to 100 kV at a full-load current of 21 A for the 2 MW klystron Transmitter.  No crowbar circuit is needed because the solid state switching approach leaves little stored energy to be dissipated during a shut-down.  In addition to the HVPS, the integrated transmitter system includes PLC controls and interface, water-cooling and monitoring system, high-voltage oil tank assembly, klystron and magnet supplies, and a custom designed user interface, as well as all safety interlocks, monitoring and operational features.
