Design, fabrication and test of a 5 GHz klystron based on the kladistron principle
arxiv(2024)
Abstract
A new bunching method, named "kladistron" has been developed at CEA in order
to provide high efficiency klystrons. A first "kladistron" prototype was
designed and realized. It was adapted from the 4.9 GHz TH2166 from Thales,
where the interaction line was transformed from 6 to 16 cavities. The design
and fabrication phases of this prototype are developed in this paper. The
kladistron prototype was tested in Thales facility. Its efficiency is finally
lower (41
at 4.96 GHz. After analysis of the experimental results, it is concluded that
the discrepancy between design and real frequencies is the cause for the low
efficiency while the spurious oscillation results from a high gain peak at 4.96
GHz.
