Abstract :
The TESLA Test Facility (TTF) Linac, under construction at DESY by an international collaboration is an R&D test bed for the superconducting cavity variant of the TeV scale future linear colliders. The main body of the TTF Linac will consist of four cryomodules, each containing eight 1 meter long nine-cell cavities made from bulk niobium and operated at L-band (1.3 GHz) frequency. The base accelerating goal is 15 MV/m. While a first injector is going to be installed in 1995 and will provide 8 mA beam current within 800 μs long macro pulses at 216 MHz bunch repetition rate, a second injector based on a BNL like RF-gun combined with a standard TESLA cavity as preaccelerator and with a bunch compressor is under development. This injector will need to operate with a bunch charge of 5×x10´0 electrons at 1 MHz bunch repetition rate; the macro pulse length is again 800 μs and the injector output energy approximately 20 MeV. Overview and status of the linac construction will be given. Plans for the future use of the TTF Linac are presented
