Abstract: Beijing X-ray free electron laser test facility (BTF) will reside in the BEPCⅡ Linac, which is the best electron linac in China. The BTF will not use the existing DC gun pre-injector, but use photoinjector to obliquely inject beam to the main linac of the BEPCⅡ. At the same time,three accelerator sections will be removed in order to install two magnetic compressors to compress the electron bunch. After the accelerator section A46, the beam is extracted and injected to the undulator through high energy transport line. The BTF will provide the electron beam with the energy of 1.18GeV, the energy spread of 0.15%, and the normalized emittance of less than 2.5mm.mrad.
