Abstract :
A design improvement to the VKU-7785E1 klystron electron gun has been successfully implemented which reduces the frequency of grid (cathode to focus electrode) voltage arcs. The benefits of implementing the improved gun into production has been an increase in manufacturing yield at CPI, dramatic reduction in in-coming test time by the systems integrator, and dramatic reduction of field returns, resulting in improved on-time delivery of the amplifier systems to the end user.
