Properties of TGFs Observed with the New TGF capabilities of Fermi-GBM

The Gamma-ray Burst Monitor (GBM) on the Fermi Gamma-ray Space Telescope Observatory (Fermi) trigger system is now responding to high-energy counts from the BGO detectors. This has resulted in an 8-fold increase in the number of detected TGFs, to ~2 per week. A further enhancement in operations over selected regions of the Fermi orbit also allows un-triggered, weak TGFs to be detected. It is now possible to detect TGFs with high certaiinty with as few as ~10 counts. This eliminates problems due to system deadtime and pulse pile-up, and greatly expands the dynamic range of TGF intensities being observed. Some features resulting from these new capabilities will be presented.
