  • Quasi-adiabatic calorimeter for measuring the energy transported by radiation
    Patent number: 4765749
    Abstract: Calorimeter for measuring the energy transported by radiation. This calorimeter comprises an absorbing element able to absorb radiation and having an outer face exposed to the radiation and an inner face, said element undergoing a temperature rise during the interaction with the radiation. This temperature rise is measured by a thermopile. The calorimeter also comprises calibration means constituted by a strip-like resistive deposit in direct contact with the inner face of the absorbing element over at least 50% of the surface thereof. Application to the measurement of the energy transported by electromagnetic radiation or a particle flux.
