Abstract

In synchrotron radiation sources short pulses of coherent THz radiation is emitted when the length of electron bunches becomes sufficiently small. A detector system based on a superconducting NbN ultra-fast bolometer with an intrinsic response time of about 100 ps was jointly developed by the University of Karlsruhe (Institute of Micro- and Nanoelectronic Systems) and German Aerospace Center (Berlin) and implemented at the storage ring ANKA to time-resolve radiation emitted by single electron bunches.
