Abstract
  • Since the first in orbit activation of the PICsIT detector, frequent spikes have been noticed in its count rate. Tracks in the detector images, corresponding to the spikes, indicate that these events are generated by interaction of cosmic rays with the detector plane. Since these events constitute a significant fraction of the instrument background, a dedicated study has been performed and it has been clarified that the mechanism that leads to spikes and track formation is related to the presence in the CsI crystals of phosphorescence states having decay times of the order of 100 ms. We have also shown that these events, thanks to their temporal characteristics, can be removed from the PICsIT data when the instrument is in Photon by Photon mode. Moreover, thanks to the pixellated structure of the PICsIT detector, we have also obtained evidence of the presence of numerous electromagnetic and hadronic showers generated by the primary cosmic rays. Based on observations with INTEGRAL, an ESA project with instruments and science data center funded by ESA member states (especially the PI countries: Denmark, France, Germany, Italy, Switzerland, Spain), Czech Republic and Poland, and with participation of Russia and USA.
