Title:
DETECTION DEVICE AND RADIATION IDENTIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/048759
Kind Code:
A1
Abstract:
Provided is a detection device that detects radiation, the detection device comprising: a container containing gas; an electron detector that is located inside the container and that detects electrons generated by Compton scattering and generates an analog signal; a drift electrode facing the electron detector; a radiation detector that detects radiation scattered by Compton scattering and generates an analog signal; a first readout circuit that digitizes an analog signal generated by the radiation detector to generate first data, and stores the first data in a first buffer; and a second readout circuit that digitizes the analog signal generated by the electron detector to generate second data. The first readout circuit transmits first final data including the first data stored in the first buffer to an external computer in response to a first trigger signal.
