Abstract :
Pulsed heating is one of the main factors that limit accelerating gradient in normal conducting linear accelerators. In this paper a special test device is described that is designed to determine the maximum achievable surface electric field limit due to pulsed heating and metal fatigue. The power source for driving the test device is to be the Omega-P 34 GHz pulsed magnicon. Utilization of a few MW of μsec pulse width should allow one to obtain pulsed heating excursions exceeding 600°C. The test device is designed with a to allow measurements for copper, for other materials, and for different procedures of surface preparation.
