11 June 2004, CERN AB RF / FB, João Bento, Fritz Caspers 11 Conclusions Measurements of parameters in the frequency domain and evaluations in the time domain show that for the required application, this structure should fit the purposes, and in particular, attenuation and rise time degradation are within specifications. Acknowledgment: a particular thank to Tom Kroyer for his help on calibrating and setting-up the VNA.
