The CLIC Test Facility 3 (CTF3) injector will provide pulsed beams of
high average current; 5 A over 1.56 μs at 140 keV. For transverse beam sizes
of the order of 1mm, as foreseen, this implies serious damages to the
commonly used scintillating screens. Optical Transition Radiation from
thermal resistant radiators represents a possible alternative. At low
energy the OTR emission is feeble and distributed over a large solid
angle. In order to investigate the feasibility of such a diagnostic
studies have been carried out on a test 80 keV photo injector. The
experimental set-up is described and the results are compared to the
calculations based on the OTR emission theory. Our conclusions for the
design of the CTF3 injector profile monitor are also given.
