Runaway electron (RE) experiments are an important part of the ongoing ITER-relevant studies on COMPASS, as the REs could severely damage the plasma facing components in the future fusion reactors. A relativistic accelerated charged particle in the presence of the magnetic field emits SynchrotronRadiation (SR). As SR is emitted preferentially in the direction parallel to the RE motion (the so-called headlight effect) it should be observed from a tangential view. In this paper it is demonstrated that the relative intensity of the infrared (IR) radiation is correlated with the critical energy Wc for production of REs. Furthermore, analysis of the firstdirect observation of the RE beam in the COMPASS tokamak with the calibrated camera is presented.
