Description
Summary:Over the past decades, low-energy electron accelerators have been used worldwide for surface curing and sterilization. The beam nonuniformity is an important parameter of the low-energy electron beam with large cross-sections. A simple and accurate measurement system of nonuniformity for the low-energy electron beam with large cross-sections was developed. The main concept consists in the measurement of nonuniformity, which is realized by using a linear actuator to drive two scanning wires through the beam＇s cross-sections at a fixed speed. The beam distribution can be obtained by sending/collecting the current signals to/from the Data Acquisition （DAQ） software on a laptop by a USB DAQ card. This device is very convenient for the performance testing of a new accelerator at the manufacturer＇s site. The distribution of the homemade low voltage electron accelerator EBS-300-50 was measured and evaluated.
