Differential beam current measurement (DBCM) Electronics

DBCM system we designed can accomplish the real-time monitoring of 6 flow beam intensity, its difference comparison and the output of interlock protection signal functions. Data online processing with FPGA is used for hardware design. Some designed average compensation algorithms are used to estimate whether beam losses occur to determine what time to produce chain protection signal (response time within 6 μs).
