GRB 210213B: Insight-HXMT/HE detection
Abstract
At 2021-02-13T06:52:27.18 (T0), Insight-HXMT/HE detected GRB 210213B (trigger ID: HEB210213286) in a routine search of the data, which also triggered CALET (trigger ID:1297234318) and INTEGRAL. The Insight-HXMT/HE light curve mainly consists of multiple pulses with a duration (T90) of 15.33 s measured from T0+1.55 s. The 1-ms peak rate, measured from T0+1.66 s, is 5983 cnts/sec. The total counts from this burst is 31576 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).
