It enables unprecedented time dependent measurements within a large bandwidth, dynamic range and unambiguous RF indication in the entire D-Band (110-170 GHz). Special attention was given to the investigation of parasitic RF oscillations, and the analysis of the interplay of thermal cavity expansion and ionization-based space charge neutralization at the start of long RF pulses UR - https://www.ksp.kit.edu/9783731503750 UR - https://directory.doabooks.org/handle/20.500.12854/60942 ER -
