Runaway electrons are a promising tool for the study of magnetic turbulence in a tokamak plasma. Here the confinement times, energy, birth-rate, beam dimensions and energy distribution of relativistic runaway electrons (10-35 MeV) are diagnosed by means of the infrasynchrotron radiation emitted. During the first second, the electrons obey the freefall acceleration very well. After approximately 2.5 s, the observed energy saturates. An explanation in terms of reaching the radiation limit is consistent with the value observed for the pitch angle. Loss mechanisms were found in the cases of gas puff experiments and NBI.
