Abstract	A photoinjector designed for Electron Beam Test Facility (EBTF) and Compact Linear Accelerator for Research and Applications (CLARA), a proposed FEL test facility is described. The photoinjector is based on a 2.5 cell Sband photocathode RF gun operating with a copper photocathode which is driven by a third harmonic of Ti:Sapphire laser (266 nm) installed in dedicated thermally stabilized room. The injector will be operated with laser pulses with energy of up to 2 mJ, a pulse duration of 80 fs RMS and initially a repetition rate of 10 Hz, with the aim of increasing this eventually to 400 Hz. At a field gradient of 100 MV/m provided by a 10 MW klystron, the gun is expected to deliver beam pulses with energy of up to 6 MeV. Bunch length and emittance of electron bunches essentially depend on the bunch charge and vary from 0.1 ps at 20 pC to 5 ps at 200 pC and from 0.2 to 2 mmmrad respectively. Additional compression of the electron bunches required for CLARA will be provided with a velocity bunching scheme and a dedicated chicane.
