Electron beam uniformity detection device for irradiation accelerator

High-voltage electron accelerator is widely used in irradiation processing industry. Beam uniformity of the accelerator has very important impact on the quality of irradiated products. Accurate measurement of beam uniformity helps to improve product quality and production efficiency. In this paper, the electron beam uniformity detection device is designed based on Faraday cup array followed by the signal shaping circuit and the digital signal processing system. Finally, the computer offers friendly interface to help users understand the operating state of the accelerator and the electron beam uniformity information. This device uses DSP technology to process the signal and optical fibre to communicate, which greatly improves noise immunity capability of the system. Through such a high precision, easy to use detection device, user can get the accelerator beam irradiation uniformity information which is very useful to direct the industry radiation process.
