Title:
ELECTRONIC PULSE DETECTION APPARATUS AND ELECTRONIC PULSE DETECTION CHIP
Document Type and Number:
WIPO Patent Application WO/2003/029767
Kind Code:
A1
Abstract:
An electronic pulse detection apparatus includes an MCP having a plurality of capillaries arranged in a matrix for increasing the number of electrons and an electronic pulse read out chip (30) arranged at the output side of this MCP. The electronic pulse detection chip (30) has anodes (32) and detection transistors (34) arranged to correspond to capillaries. An electron pulse comes into the anode (32) from the MCP. Each of the detection transistors (34) has a drain connected to a corresponding anode. The detection transistors (34) have gates of each line connected to one another so as to be turned on&sol off by line and sources of each row connected to a switch circuit (80) and are connected via the switch circuit (80) to a current&sol voltage conversion resistance RL. The current&sol voltage conversion resistance RL converts into voltage the current flowing when an electronic pulse comes into the anode (32), and inputs the voltage to an operational amplifier (90). Thus, it is possible to detect weak light and radioactive rays two−dimensionally.
