A NEW HIGH POWER KLYSTRON FOR THE SLAC B-FACTORY

Abstract

A new klystron for driving the SLAC B-Factory is cur-rently under development at Philips. Detailed numerical analysis has been carried out in order to meet all the re-quirements. Particular attention is paid to the bandwidth and phase behavior of the tube because the upper limit in group delay is given by the control system of the B-Factory. Although bandwidth and efficiency are compet-ing demands- not easily met by the same design- the simulation predicts very high efficiency. Another impor-tant aspect which is being taken into account for the de-sign is operational stability of the tube. The design con-cept and numerical as well as measurement results will be presented. 1 DESIGN CONCEPT The main requirements for the operational parameters of the tube are listed below: • operating frequency 476 MHz, • output power 1.2 MW, • micro perveance 0.83- 1.3, • gain> 43 dB, • bandwidth (-1 dB) +/- 1.5 MHz, • group delay (+/- 0.5 MHz) < 150 nsec
