| 英文摘要 | During the commissioning phase, at 2017-08-17T21:47:34.00 (T0),Insight-HXMT detected GRB 170817B (trigger ID: HEB170817908)in a routine search of the data, which was also observed byFermi/GBM (Roberts et al. 2017, GCN 21540).The Insight-HXMT light curve consists of multiple pulseswith a duration (T90) of 2.64 s measured from T0+0.40 s.The 50-ms peak rate, measured from T0+0.40 s, is 6135.4 cnts/sec.The total counts from this burst is 5353.1 counts.URL_LC: http://www.hxmt.org/images/GRB/HEB170817908_lc.jpgAll measurements above are made with the CsI detectors operating in theregular mode with the energy range of about 80-800 keV (record energy).Only gamma-rays with energy greater than about 200 keV can penetratethe spacecraft and leave signals in the CsI detectors installed insideof the telescope.The time-averaged spectrum from T0 to T0+3.60 s isadequately fit by a Power Law model with spectral index = -1.60 +/- 0.05.The energy fluence is (1.09 +/- 0.05)E-05 erg/cm^2 in 200 - 5000 keV inthis time interval.The analysis results presented above are preliminary;final results will be published elsewhere.Insight-HXMT is the first Chinese space X-ray telescope, which was fundedjointly by the China National Space Administration (CNSA) and the ChineseAcademy of Sciences (CAS).
