Abstract : The principle of operation of this method is as follows. A metallic disc which is periodically rotated by an electric motor, is mounted with several ceramic plates covered with a semiconducting heating layer which in turn is covered with the thermolucent phosphor CaSO4(Mn). The plates with the phosphor are irradiated in turn and then placed before a photomultiplier. A current is passed through the semiconducting layer, the plate begins to heat, and the energy stored by the phosphor is re-emitted. Energy re-emitted in the visible spectral range is detected by the photomultiplier. The measurement results are transmitted by a radio telemetry system to the earth. The de-excited plates are cooled by heat transfer to the instrument housing.
