We are constructing an injector test facility (ITF) for the PAL XFEL. The target of the facility is to demonstrate an emittance of < 0.5 mm mrad (projected, normalized rms) at the beam charge of 200 pC with small energy spread and high stablities. By collaborating with the RADIABEAM Technologies*, we have developed beam diagnostics with enough precision and reliability to provide beam information including beam energy, energy spread, charge, profile, position, and bunch length. Resolutions of the beam-size and position measurements will be 17.5 um (rms, for OTR screens) and < 10 um (rms) respectively. A S-band transverse deflecting cavity will be used for measuring the bunch length with resolution down to 10 fs. In this article we report on current status of the PAL-XFEL injector test facility with emphases on its beam diagnostics.
