Abstract: A radiation detector 1 includes a Peltier device (electronic cooling unit) for cooling a radiation detecting element, and the heat releasing part of the Peltier device is in thermal contact with a cold finger (thermally conductive part). The cold finger is made of a material with higher thermal conductivity than that of the base, and penetrates the base. The heat from the radiation detecting element is conducted from the heat releasing part of the Peltier device to the cold finger, and is dissipated to the outside of the radiation detector through the cold finger. As such, heat is efficiently dissipated from the radiation detecting element.

Abstract: A radiation detector employed in a radiation detection apparatus and a fluorescent X-ray analyzer includes: a first circuit board on which a semiconductor radiation sensor is mounted and which is cooled by a Peltier device (an electronic cooling unit); and a second circuit board set apart from the first circuit board. A plurality of lead pins are joined to the second circuit board. Then, the first circuit board and the second circuit board are wire-bonded to each other. In comparison with conventional wire bonding performed onto the tips of lead pins, the work of connection is easy, the productivity is high, and the reliability of connection is high. Further, the second circuit board not requiring cooling is set apart so that cooling is concentrated on the first circuit board. This permits size reduction of the radiation detector.

Abstract: In the radiation detector, a capacitor is connected between a connecting wire which is connected with a preamplifier (amplifier) and another connecting wire. Specifically, the capacitor is connected between the connecting wire and another connecting wire which has the lowest electric resistance with respect to a signal wire among connecting wires connected with a radiation detecting element. This prevents electric current produced by static electricity from flowing to the signal wire and prevents the signal wire or the preamplifier from being damaged by static electricity. A circuit element for a countermeasure against static electricity is not provided at the signal wire, and therefore input capacitance of the preamplifier is kept low. Accordingly, the radiation detector is improved by a sufficient countermeasure against static electricity while input capacitance of the preamplifier is kept low.

Abstract: Three or more tubular radiation detectors are arranged around an irradiation axis of radiation directed to a sample from an irradiation unit such that the end face thereof is opposed to the position irradiated with radiation. The radiation emitted from the sample enters the radiation detector through an end face and is detected. In the radiation detector, the length in the direction parallel to the straight line which is on the plane orthogonal to the irradiation axis and is perpendicular to the central axis continuously decreases from a position along the central axis to the end face. The size of each radiation detector around the irradiation axis is reduced as it approaches the end face, preventing the radiation detectors from interfering with one another and allowing the radiation detector to be closer to the sample compared to the conventional case. This makes it possible for the radiation detection apparatus to detect radiation from the sample with high efficiency.
