Abstract
One possible extension of the FEL activity at DESY is connected with the installation of an additional FEL beamline providing tunable UV radiation with peak and average power of 220 GW and 7 kW, respectively. This report presents the feasibility study of a high-intensity, polarized, monochromatic gamma source at the TESLA Test Facility. Gamma quanta are produced in the process of Compton backscattering of the UV FEL radiation on 1 GeV electrons of the TTF accelerator. The ultimate intensity of the gamma source can reach a value up to 1012 gamma quanta per second with a maximum energy of about 100 MeV. The energy resolution of the gamma source can be reduced down to a value of about 0.2%. Potential applications of the intense gamma source at the TESLA Test Facility are discussed as well.
