TOF-ERDA,Detection efficiency,Solid angle

TOF-ERDA system was upgraded to a large solid angle and detection efficiency was improved. The solid angle was 0.42 msr, Which is 2.6 times higher than the previous value of 0.16 msr caused by the increased sensitive area of the transmission detector. The detection efficiency of lithium was improved from 50~60% to 70~80% by changing the MCP detector.
