Abstract (englisch):

For future upgrades of some CERN kicker systems, doubling of the driving current by replacing a matched impedance by a short circuit termination is of interest, because it allows a doubling of the kick strength, without an increase in magnet length or generator voltage. Therefore, for driving kicker magnets featuring a short-circuit termination, a novel approach for a pulse generator architecture based on an inductive voltage adder is currently being investigated. So far, a branch module for an inductive voltage adder has been designed and built. To account for the reflection at the short circuit, the branch module has a topology comprising two independently controlled semiconductor switches. This allows energy to first be injected into the kicker magnet, then to circulate the resulting current in a freewheeling-interval, and the energy to be reabsorbed at the end of the pulse. To validate the operation of the module, it has been tested with a resistive load of 10Ω . This test revealed undesired oscillations of the pulse shape. In order to investigate these issues and to improve the circuit, a circuit simulation model has been developed including relevant parasitic parameters of the circuit elements. ... mehr
