Abstract
A bolometer system for measuring energy flux in a noisy electromagnetic environment is described. The system consists of a platinum foil grid, heated by energy flux from a fusion plasma experiment, whose resistance controls the frequency of a 5‐MHz oscillator. The information about heating of the foil is thus shifted to a high‐frequency band, and noise pickup (which is mainly at lower frequencies) is reduced.Keywords
