GRB 200703B: Insight-HXMT/HE detection
Abstract
At 2020-07-03T23:16:52.80 (T0), Insight-HXMT/HE detected GRB 200703B (trigger ID: HEB200703970) in a routine search of the data, which was also triggered by Fermi/GBM (GCN #28059) and AstroSat/CZTI (GCN #28060). The Insight-HXMT/HE light curve mainly consists of multiple pulses with a duration (T90) of 0.161 s measured from T0-11.360 s. The 1-ms peak rate, measured from T0+17.803 s, is 1950 cnts/sec. The total counts from this burst is 23638 counts.

Only gamma-rays with energy greater than about 200 keV can penetrate the spacecraft and leave signals in the CsI detectors installed inside of the telescope. Insight-HXMT is the first Chinese space X-ray telescope, which was funded jointly by the China National Space Administration (CNSA) and the Chinese Academy of Sciences (CAS).
