Device for detecting ionizing radiation

A spectrometer for detecting ionizing radiation comprising a vacuum chamber having an entrance window to pass the radiation therethrough;

• a thermoelectric cooler formed by a set of Peltier elements, said thermoelectric cooler having a hot side and a cold side and being arranged within said vacuum chamber;
• a heat conducting plate mounted on said cold side of said thermoelectric cooler a radiator mounted on said hot side of said thermoelectric cooler;
• a first set of Peltier elements forming a thermoelectric battery which comprises at least two stages with a heat conducting plate therebetween, said first set being integral with said thermoelectric cooler and arranged on said heat conducting plate, thus developing the minimum temperature conditions on said cold side of said first set;
• a semiconductor detector mounted on said cold side of said first set of Peltier elements;
• a second set of Peltier elements, having a hot side and a cold side and being integral with said thermoelectric cooler, said hot side of said second set being in contact with said heat conducting plate, the Peltier elements of said second set being stacked so as to develop the maximum refrigeration capacity conditions on said cold side of said second set;
• a field-effect transistor mounted on said cold side of said second set, the Peltier elements of said second set being stacked so as to develop the maximum refrigeration capacity conditions on its cold side and to form a one-stage thermoelectric battery.
