| Zusammenfassung |
| Terrestrial Gamma-ray Flashes (TGFs) were first observed by CGRO in 1994 and have
continued to be observed by current gamma-ray telescopes such as Fermi/GBM. Today, TGFs
are an area of continued interest and research although many questions remain
despite close to 20 years of active research. One of the main reasons for the lack
of understanding is the extremely fast, hard and intense nature of TGFs causing
numerous instrumental effects in space based observatories. One such effect is that of
dead-time which in Fermi/GBM is 2.6μs-count or up to ~ 1% of the TGF duration per
count.
A statistical temporal deconvolution method to recover the
dead-time losses has been developed by members of the GBM
collaboration1
. Simulations were performed using this method to determine how effective it is at
reconstructing TGF time profiles. Presented here is the method and results of the
study. |
