TL;DRAbstract

A VHF high-power klystron for the Japanese Hadron Facility (JHF) was studied at KEK and Toshiba Co.. The main parameters of this klystron are a frequency of 324 MHz, a 3 MW output power and a 650 sec pulse width. In order to develop this klystron we had started to design the klystron and to prepare tests for the key components: the high-power rf window and a modulation-anode type beam tester. Using the existing VHF (432MHz) high-power klystron we completed a high-power test of a coaxial window, which was designed with the HFSS code. The full design of the klystron is also under progress. In this article, the specifications of the VHF klystron, the mounting configuration, the design of the klystron and the high power-test results of the coaxial windows are reported.
