2.4 kV DC were triggered by an external overvoltage pulse applied across the thyristor main electrodes. In
experiments a voltage rise rate across the thyristor was changed from 1 to 6... -

"Experience in rad hard tests of LBDS"
LHC beam dumping system (LBDS) employs altogether 800 HV GTO like thyristors and 480 HV triggering IGBTs. It delivers up to 1 million amperes to 30 extraction and 20 dilution magnets in order to safely deposit both 7 TeV beams on their respective dump blocks. Because of crucial importance of reliable operation of LBDS for LHC safety, various failure mode...

"Experience of Solid-state modulators for HV kickers and septa at SOLEIL"
The pulsed systems for beam injection & extraction at SOLEIL only use solid-state switches in the pulsers. During the technical design of the machine, this had been a strong requirement in order to get excellent availability and reliability of the equipment themselves but also to obtain excellent Top-Up performance,...
