From: The GRB221009A gamma-ray burst as revealed by the gamma-ray spectrometer onboard the KPLO (Danuri)
KGRS data for deadtime, HV variations and gamma-ray spectra of the main and shielding detector for the 7 min of the GRB221009A event. The standard deviation of the high voltage during the period of the gamma-ray burst is less than 0.1%, so the electronic circuit is believed to be unaffected by the gamma-ray burst.
