Abstract
A carbon bolometer, used as a high speed thermometer for observing heat pulses in solids at low temperatures, is described. In conjunction with a KCl substrate, the carbon bolometer was compared with a thin film superconducting bolometer. The carbon bolometer was found to have a frequency response flat to at least 2.5 kHz.
