AB  - China Spallation Neutron Source (CSNS) consists of 80 MeV H⁻ LINAC, 1.6 GeV RCS, RTBT line and one target. Many wire scanners and beam loss monitors (BLM) distributed along the LINAC and the RTBT for the profile and beam loss measurement. For the wire scanner, signal on the wire induced by the secondary electron is used for the profile measurement. Signal lost may happen when the wire or the signal chain shorted, thus a backup readout chain is required for the accident condition. As for the BLM, it is difficult to do the online calibration to see how sensitive the monitor is. Based on the two requests above, a crosscheck study was carried out recently, one wire scanner and the BLM next to it were chose at LINAC and RTBT. Both wire signal and BLM signal were recorded while the wire scanner crossing the beam. We found these two type of signals have the same accuracy for the profile measurement, and ~ 1 μA beam loss induced by the wire disturbance can be detected. Also thermal electron emission suspected happening during the measurement. More detailed experiment will be carried out in December. Secondary electron emission efficiency of the tungsten wire and thermal electron emission rate will be verified then.
