The invention provides a heavy ion beam current real-time monitoring device and an irradiation test system. The heavy ion beam current real-time monitoring device comprises a detection structure and a diaphragm structure. The detection structure comprises a plurality of detectors used for monitoring heavy ion beam current in real time; the diaphragm structure is arranged in front of the detection structure along the incident path of the heavy ion beam current; the diaphragm structure comprises a diaphragm piece, the diaphragm piece comprises a plurality of detection diaphragm groups which are arranged in the diaphragm piece in a penetrating manner, wherein each detection diaphragm group comprises a plurality of detection diaphragms with different apertures, and one detection diaphragm group corresponds to one detector in a plurality of detectors; and the diaphragm piece rotates by taking the center line of the diaphragm piece as a rotating shaft so as to switch one detection diaphragm with different apertures in one detection diaphragm group to correspond to one detector. By utilizing the device disclosed by the invention, the fluence rate and uniformity of the heavy ion beam current can be monitored in real time in a large range in the sample irradiation process, the monitoring accuracy is high, the diaphragm does not need to be frequently disassembled and assembled to be replaced in the irradiation process, and the test efficiency is greatly improved.
Description
Technical field[0001]The present disclosure relates to the field of heavy ion detection, and more particularly to a real-time monitoring device and an irradiation test system for heavy ion beam current.Background technique[0002]In the prior art, the single-particle effect irradiation experiment for the heavy ion is mostly used to make beam monitoring in the manner of placing a bundled aperture in the front end of the detector. The beam diagnostic system of the irradiation device in the prior art is mainly taken to monitor the size and uniformity of the quantity rate in real time in the outer side of the beam line. For example, a plastic thin film scintillator detector is mounted on the beam flow line, the film detector thickness, which can take a small portion of the energy to achieve real-time monitoring of the beam flow when wearing a thin film. However, all the restricted apertures in the prior art are fixed apertures, and the range of quasiors measured by the detector is narrowe...
