摘要： 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 chip 30 disposed on an output side of the MCP. The electronic pulse detection chip 30 includes anodes 32 and detection transistors 34 both provided so as to correspond to the respective capillaries. Electronic pulses are incident on the anodes 32 from the MCP. Drains of the detection transistors 34 are connected to the corresponding anodes. The detection transistors 34 on the same row are connected to one another at gates thereof and turned on/off as a unit, and sources of the detection transistors 34 on the same column are connected to a corresponding switch circuit 80 as a unit to be connected to a current-voltage conversion resistance RL via the switch circuit 80. The current-voltage conversion resistance RL converts a current, which flows therethrough when the electronic pulses are incident on the anodes 32, to a voltage and inputs the voltage to an operational amplifier 90. This makes it possible to detect feeble light and radiation ray two dimensionally.
