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 chip30disposed on an output side of the MCP. The electronic pulse detection chip30includes anodes32and detection transistors34both provided so as to correspond to the respective capillaries. Electronic pulses are incident on the anodes32from the MCP. Drains of the detection transistors34are connected to the corresponding anodes. The detection transistors34on the same row are connected to one another at gates thereof and turned on/off as a unit, and sources of the detection transistors34on the same column are connected to a corresponding switch circuit80as a unit to be connected to a current-voltage conversion resistance RLvia the switch circuit80. The current-voltage conversion resistance RLconverts a current, which flows therethrough when the electronic pulses are incident on the anodes32, to a voltage and inputs the voltage to an operational amplifier90. This makes it possible to detect feeble light and radiation ray two dimensionally.
