| Zusammenfassung |
| The Large Observatory For x-ray Timing (LOFT) is an astrophysics space mission designed
to study the neutron star structure and equation of state of ultra-dense matter and to explore
the conditions of strong-field gravity. LOFT was selected by ESA as a candidate medium
class mission scheduled for flight in 2022 and is currently in the assessment phase.
Although LOFT primary scientific objective is the timing of astrophysical x-ray
sources, it will be also suitable to detect Terrestrial Gamma-ray Flashes (TGFs)
as one of its many secondary scientific targets. The LOFT payload is composed
of two instruments: the Large-Area Detector (LAD) and the Wide Field Monitor
(WFM). LAD is a collimated instrument sensitive in the energy range 2-80 keV,
with a very large effective area of 10 m2 at 8 keV and 1 m2 at 30 keV on axis, and
an energy resolution of 200 eV at 6 keV. The LAD primary energy range is 2-30
keV for sources inside the Field of View (FoV), and the 30-80 keV energy range
is specifically intended for out-of-FoV events, which will be the typical case for
TGFs. WFM is a coded mask instrument sensitive in the same energy range of
the LAD, with |
