AI Article Synopsis
- A neutron bang time (NBT) diagnostic system has been installed on the Shenguang-III prototype to measure the timing of neutron production during fusion events.
- The system utilizes a combination of a plastic scintillator and a micro-channel plate photomultiplier tube (PMT) to detect neutron activity, with an optical fiber bundle connecting the two components.
- It can accurately measure bang times for neutron yields above 10^7, with a timing precision of better than 60 picoseconds, and correlates the bang time with the start time of laser-generated x-ray pulses from 200 ps laser hits on gold targets.
Article Abstract
A neutron bang time (NBT) diagnostic system has been implemented on Shenguang-III prototype. The bang time diagnostic system is based on a sensitive fusion neutron detector, which consists of a plastic scintillator and a micro-channel plate photomultiplier tube (PMT). An optical fiber bundle is used to couple the scintillator and the PMT. The bang time system is able to measure bang time above a neutron yield of 10(7). Bang times and start time of laser were related by probing x-ray pulses produced by 200 ps laser irradiating golden targets. Timing accuracy of the NBT is better than 60 ps.
