  TETD (Toshiba Electron Tubes & Devices Co., LTD.) has been developing a wide variety of klystrons and input couplers in collaboration with some Japanese research institutes. This article presents recent results of the development including a C-band and an S-band pulsed klystrons for SPring-8 Joint Project for XFEL, 1.3-GHz horizontal MBK for DESY and a 1.3-GHz TTF-type input coupler for the European XFEL. As an application to fusion experimental devices, development of a 5-GHz, 500-kW CW klystron for KSTAR and a 170-GHz quasi CW gyrotron for ITER are also presented.

  Toshiba Electron Tubes & Devices (TETD) has been developing 10-MW L-band Multi-Beam Klystrons (MBKs) for the European XFEL project and possibly for future linear colliders. In order to allow horizontal installation in the XFEL tunnel, the horizontal version of MBK, MBK E3736H, has been designed, fabricated and tested by TETD. The MBK has six low-perveance beams operated at low voltage of less than 120 kV (for 10MW) and six ring-shaped cavities. In the successful acceptance testing at TETD in August 2007, the MBK achieved an output power of 10.3 MW at the beam voltage of 117 kV and at the RF pulse width of 1.5ms with efficiency of 67%. This test demonstrated that MBK E3736H fulfills all the requirements necessary as the RF power source of the XFEL linac.
