Abstract

Room-temperature detector, manufactured by the company "SPINOR" (Tomsk Russia) was tested for the investigations of the coherent synchrotron radiation characteristics at the bent electron beam of FLASH (Hamburg) in the wavelength region 0.5-3 mm. Detector is based on a low-threshold diode and a broadband antenna with a built-in preamplifier. The detector characteristics allowed us to measure a radiation pulse from separate electron bunches from electron train. The measured coherent synchrotron radiation spectral characteristics in comparison with ones, measured using the cryogenic bolometer show a good homogeneity of the spectral sensitivity of our detector for wavelengths longer than 1.5 mm. The comparison of temporal characteristics with the well-established pyro-electric detectors shows a response time around 1.5 ns. The measured detector sensitivity was about 100 MV/J.
