Abstract

A new metal resistor bolometer has been developed by applying thin film technology. It is composed of three layers, a 4 mu thick radiation absorber made of gold, a 7.5 mu thick kapton dielectric, and a 0.1 mu thick 5 k-OMEGA gold resistor. This detector with the appropriate electronics shows a linear response to radiation power, including both neutral particle emission and electromagnetic radiation from the soft x-ray part of the spectrum to the infrared. The bolometer has a very high operating reliability and sufficient suppression of ambient interference under extreme environmental conditions, such as high neutron and gamma radiation fluxes, high temperatures, mechanical vibrations, and strong electromagnetic fields. In plasma discharges in the ASDEX tokamak a radiation detection limit of 100 muW/cm**2 was obtained at a time
