GRB 200122B: Insight-HXMT/HE detection
Abstract
At 2020-01-22T05:18:20.20 (T0), Insight-HXMT/HE detected GRB 200122B (trigger ID: HEB200122221) in a routine search of the data, which was also triggered by Fermi/GBM (NUM #601363105). The Insight-HXMT/HE light curve mainly consists of a single pulse with a duration (T90) of 2.16 s measured from T0-0.53 s. The 1-ms peak rate, measured from T0-0.06 s, is 1340 cnts/sec. The total counts from this burst is 1335 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).
