An X-band transverse deflector has been successfully developed for femtosecond electron and x-ray pulse temporal diagnostic at the LCLS [1]. The working frequency for the deflector is 11.424 GHz. New free electron laser LCLS-II has two undulator beamlines, one Soft-X-Ray and another Hard-X-Ray. The Hard-X-Ray line uses two one-meter long X-band deflectors for beam diagnostics. We have designed, build, installed and commissioned another, 1.5 meter long X-band deflector in the Soft-X-Ray beam line. Both Hard-X-Ray and Soft-X-Ray deflectors share one klystron. RF power is transmitted from a 50 MW klystron to a tunnel in an overmoded circular waveguide and then directed to either of the deflectors using a remotely controlled RF switch. The power split ratio could be changed arbitrarily, and both deflectors could work simultaneously. In this article, we provide details on the development and commissioning of the new deflector.
