Abstract :
Thales Electron Devices has been developing and manufacturing 10MW L-band vertical Multi Beam Klystrons (TH1801) for TTF, FLASH and PITZ machines at DESY for more than 10 years. At this point, 8 tubes have been installed at DESY with more than 80 000 hours of cumulated RF operation. All over these years, THALES has been collecting data on MBK tubes behavior which permitted to improve continuously the design margins and reliability. In order to allow horizontal installation in the XFEL tunnel, a horizontal version (TH1802) was fabricated, tested and qualified. The key performance of this tube is its high stability under all various operating conditions.
