Gold film resistance thermometers, some hundred of atoms thick, have been used to detect the passage of shocks in a shock tube. The construction, calibration, and mounting of these films is described. Experiments show that the gold films respond to rapid changes of gas temperature of several degrees centigrade and have negligible effect on the gas flow. A sensitive voltage amplifier is described. This enables the gold film to be used in the shock tube under conditions in which the limit of sensitivity is the thermal noise of the gold film itself. A simple theoretical study suggests that the response time of a gold film thermometer could be as low as
