Abstract :
In this paper we discuss the possibility to generate subpicosecond electron bunches with a small emittance directly from the superconducting 5.3 cell RF gun by illuminating a photo-cathode in the RF cavity with a phaselocked 3 ps laser pulses. The bunch length compression caused by the RF force take place in the first TESLA cell of the RF gun. Numerical simulations of the beam dynamics in the RF gun and of the radiation of the corresponding electron bunch in a wiggler predict a coherent enhancement of radiation for wavelength smaller than 100 micron
