abstract = {In present day tokamaks runaway electrons can be confined
long enough to gain energies in the order of several tens of
megaelectron volts. At these energies synchrotron radiation
is emitted in the infrared wavelength range which can easily
be detected by thermographic cameras. The spectral features
of this synchrotron radiation are reviewed. On TEXTOR-94 a
diagnostic exploiting this synchrotron radiation has been
developed and is presented here. It is shown how to deduce
the runaway parameters like runaway energy, pitch angle,
runaway current and beam radius from the measurements. Based
on the experience at TEXTOR-94 the feasibility of a similar
synchrotron diagnostic on the International Thermonuclear
Experimental Reactor is discussed. The maximum emission is
expected in the wavelength range from 1-5 mum. A beam of 10
MeV runaway electrons with a current of about 15 kA will
already be detectable. (C) 2001 American Institute of
