Typical bunch length duration in synchrotron radiation facilities is around tens of pico-seconds. There are several novel methods to generate femto-seconds x-ray pulses for the applications in fast chemical reaction or phase transition and coherent vibration motion in atomics level. A superconducting crab cavity is used to create angle kick to rotate electron bunches in vertical direction, which can have the most high-average photon intensity in all methods. The short-bunch x-ray is generated from rotated bunches through insertion device. A second superconducting crab cavity is then to cancel the rotating angle of electron bunch in order to eliminate the interference to the rest of beamlines in the storage ring. An Quadruple-Bend-Achromat (QBA) lattice is designed for 3GeV Taiwan Photon Source (TPS) to generate high brightness x-ray. Various effects of the stored electron beam, due to the installation of superconducting crab cavities, were investigated.Optimal installation location and operation conditions of the superconducting crab cavities were found to the designed QBA lattice.
