| 英文摘要 | At 2019-12-27T17:21:44.14 (T0), Insight-HXMT/HE detected GRB 191227B (trigger ID: HEB191227723) in a routine search of the data, which was also triggered by Fermi/GBM, IPN and Konus-Wind (GCN #26612). The Insight-HXMT/HE light curve mainly consists of multiple pulses with a duration (T90) of 0.161 s measured from T0+0.010 s. The 1-ms peak rate, measured from T0+0.045 s, is 50,544 cnts/sec. The total counts from this burst is 4123 counts. But it should be noted that the Insight-HXMT/HE detection suffers from saturation when the count rate exceeds ~20,000 cnts/sec. The uncorrected light curve can be found at: URL_LC: http://www.hxmt.org/images/GRB/HEB191227723_lc.jpg All measurements above are made with the CsI detectors operating in the regular mode with the energy range of about 80-800 keV (deposited energy). 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).
