RADIATION DETECTOR |
摘要 |
An X-ray detector (1) is formed of amorphous selenium and is equipped with an X-ray conversion layer (17) that absorbs incident radiation and generates an electrical charge, a common electrode (23) provided on the surface of X-ray conversion layer (17) on the side exposed to radiation, and a signal readout circuit board (2) on which are arranged multiple pixel electrodes (7) that collect the charge generated by the X-ray conversion layer (17). The radiation detector is further equipped with an electrical field moderating layer (13) that is provided between the X-ray conversion layer (17) and signal readout circuit board (2) and that contains arsenic and lithium fluoride, a crystallization suppression layer (11) that is provided between the electrical field moderating layer (13) and signal readout circuit board (2) and that contains arsenic, and a first thermal characteristic strengthening layer (15) that is provided between the electrical field moderating layer (13) and X-ray conversion layer (17) and that contains arsenic.
