Abstract

A high-resolution Compton gamma camera, relating to the technical field of gamma measurement, and comprising: a high-gas-pressure tank (1) provided with a window (2), a metal film (3) being sealedly provided at the window (2), and a plurality of flange interfaces (4) being formed on the side wall or the bottom of the high-gas-pressure tank (1); a time projection chamber detector (5) which is provided in the high-gas-pressure tank (1) and is used for implementing gamma ray Compton scattering conversion and three-dimensional trajectory and energy measurement of scattered electrons; and a gamma calorimeter (6) which is located between a field cage of the time projection chamber detector (5) and the inner wall of the high-gas-pressure tank (1) and is used for implementing position and energy measurement of Compton scattered gamma and electron leakage. The camera implements high-precision measurement of Compton scattered electrons and gamma, and accurate measurement of the gamma direction and energy, providing key technical support for applications such as astronomical observation and radiation therapy.
