Description
The construction of the new FULGOR test facility (Fusion Long Pulse Gyrotron Laboratory) at KIT is in full swing. This will significantly expand the experimental capabilities at KIT to CW tests of high power gyrotrons of up to 4 MW ouput power at operating frequencies up to 240 GHz. Thus, this facility will be a significant platform for the verification of the performance of current CW gyrotrons and of future generation ECRH sources as required for example for DEMO. The 90 kV / 120A CW EPSM modulator and the extension to 130 kV/120A short pulse (5ms) should become operational in 2017.
Further key components, such as a 10 MW water cooling system (initially equipped for 5 MW), a superconducting 10.5 T magnet, one or two 2 MW ECRH test loads and new control and data acquisition systems for all these elements are being constructed or procured at the same time.
The paper describes in some detail the High Voltage DC Power Supply (HVDCPS), a so called Enhanced Pulse Step Modulator, first proposed and built by Ampegon AG for the TRIUMF project in Canada, which will be capable of supplying single stage and multi-stage depressed collector gyrotrons with up to 4 MW RF Output power. It is for the first time that such a modulator is constructed for more than 10 MW DC output power for continuous operation.
Other key components, such as a 10.5 T / 270 mm bore superconducting magnet (preferably LHe-free), the 20 kV Mains Supply, the 10 MW cooling system, the safety access system and the control and data acquisition system will be briefly outlined.
