Scaling of NLC DR RF cavity From PAC 2001, Chicago AN RF CAVITY FOR THE NLC DAMPING RINGS R.A. Rimmer, et al., LBNL, Berkeley, CA 94720, USA From PAC 1995, Collective effects in the NLC DR designs T. Raubenheimer, et al.,
Concept at 2 GHz Rf cavity Right pulse shape after compression Klystron Pulse compressor CW Phase flip 2 times per revolution period
Vacuum Electron Device Limitations for High-Power RF Sources Considerable part of former klystron domain claimed by IOTs Why? 0.1 1 10 100 1000 Frequency (GHz) Heinz Bohlen,Thomas Grant, CPI
Vacuum Electron Device Limitations for High-Power RF Sources • IOTs have operational advantages… • Efficiency • Absence of saturation • Pulse-able via RF • Small size • High linearity • …and they are less expensive! • Disadvantage: • - Low gain (± 22 dB)
