    "Thyristor-Based Switches Operating in Impact-Ionization Wave Mode for Pulsed Power Applications"

    Thyristors of tablet design with diameters of silicon wafers of 40 to 56 mm and an operating voltage of 2 to
    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,...
