摘要
A neutron diagnostic system has been installed on the MTX tokamak. The diagnostic will be used to measure both the peak ion temperature and the ion response to intense free-electron laser microwave pulses (140-250 GHz, 1-8 GW, 20-50 ns). High-speed measurements are important for studying the intense microwave absorption process. A plastic scintillator with a polymer-clad silica bundle is used for fast time response detection. Five-channel proportional counters and fission counters are used to monitor the neutron yield for a source strength from 108 to 1013 n/s. This sytem has been calibrated with a 252Cf neutron source in the vacuum vessel and is being tested using the MTX ohmic plasma.
