Abstract
An electronic pulse detection device includes: an MCP in which a plurality of capillaries configured to increase the number of electrons are arranged in matrix; and an electronic pulse reading chipdisposed on an output side of the MCP. The electronic pulse detection chipincludes anodesand detection transistorsboth provided so as to correspond to the respective capillaries. Electronic pulses are incident on the anodesfrom the MCP. Drains of the detection transistorsare connected to the corresponding anodes. The detection transistorson the same row are connected to one another at gates thereof and turned on/off as a unit, and sources of the detection transistorson the same column are connected to a corresponding switch circuitas a unit to be connected to a current-voltage conversion resistance Rvia the switch circuit. The current-voltage conversion resistance Rconverts a current, which flows therethrough when the electronic pulses are incident on the anodes, to a voltage and inputs the voltage to an operational amplifier. This makes it possible to detect feeble light and radiation ray two dimensionally.
