Abstract :
During the past years, the experience gained with the operation of RF system at the TESLA Test Facility (TTF) resulted in several modifications and improvements of its design. In addition, as the TTF is converted to become a user facility TTF II for the SASE-FEL during 2004. The electron beam energy will be increased from 250 MeV/c up to 1 GeV/c by installation of 6 TESLA cryomodules. The RF system include 4 klystrons, each of them will supply RF power to group of cavities (RF gun, module 1, module 2&3, module 4,5&6). This paper presents the performance of the digital RF control at TTF I, commissioning/extension and features of the RF control for the upgrade of the TTF II.
