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.
Claims12
A calorimeter for measuring energy transported by radiation comprising an absorbing element able to absorb said radiation having at least one outer face exposed to said radiation and one inner face, said element being exposed to a temperature increase during an interaction with said radiation;
- means for measuring said radiation increase, said measuring means being in contact with a part of a surface of the inner face of the absorbing element;
- and a selectively heatable calibration resistance on the inner face of the absorbing element, wherein the calibration resistance is in the form of a resistive material coating deposited on a part of the surface of the inner face of the absorbing element for simulating the absorbing element radiation interaction which is not in contact with the measuring means, said coating being in direct contact with said inner face of the absorbing element over at least 50% of the surface thereof.
