Abstract

We present recent progress on the development of a multiple-beam klystron (MBK) designed to operate in S-band with a 1-dB bandwidth of 13%. The amplifier is powered by an 18-beam electron gun operating at a voltage of 42 kV and a total current of 41.6 A. Measured gun voltage-current characteristics will be compared with the design predictions made by the 3D particle code, MICHELLE. Experimental measurements of the frequency and Q´s of individual cavities comprising the interaction circuit will be compared with 3D electromagnetic simulations. Finally, as available, we will also report on hot test measurements of the rf performance of the MBK.
