CV323 X-band reflex klystron

CV323 The klystron measures 210x55mm overall and weighs 600g.

This has a design very similar to the CV87. It is based on the KRN2 and K303 klystrons, and has a long tuning range.

Markings on the body are CV323, C.S. and 1413 on the shell around the lower glass section. The number 1413 also appears on three sides of the cavity assembly.
