High gradient experiments with nanosecond pulses

Within the framework of studies related to pulsed accelerating techniques, in particular for the switched power principle, the voltage hold-off for very short pulses has been measured for different materials. Following a presentation of the subject and the requirements, a brief description of the experimental set-up is given. So far gradients of 900 MV/m have been obtained with pulses of two nanoseconds and flat electrodes. The results are compared to measurements based on different experimental techniques.<
