| Abstract | The influence of external magnetic fields of up to 0.5 T on the breakdown rate between copper electrodes, subjected to pulsed DC voltages in ultra-high vacuum, is investigated. Experiments were performed with the magnetic field oriented either parallel or perpendicular to the cathode surface. A better understanding of the effect the magnetic field has on the breakdown rate in ultra-high vacuum could help inform the geometric design of RF structures for projects such as CLIC, leading to higher accelerating gradients. |
