A prototype of a bolometer with a deep thermal feedback (TF) is described. It allows stabilization of the temperature of an absorbing film at a level of 700-800A degrees C by the control of its thermal radiation. The prototype was tested on a light-ion accelerator and a T-11M tokamak. The results obtained confirm the possibility of practically realize such advantages of the TF bolometer over conventional devices as a fast response, direct measurement of the incident power, improved stability, and a reduced influence of the drift of the intrinsic parameters of the sensor. The questions of the selection of optimal structural parameters of such bolometers and calculation of their threshold characteristics are considered.
