Abstract
TIGRE is an advanced telescope for g-ray astronomy with a few
arcmin resolution. From 0.3 to 10 MeV it is a Compton telescope. Above
1 MeV, its multi-layers of double sided silicon strip detectors allow
for Compton recoil electron tracking and the unique determination
for incident photon direction. From 10 to 100 MeV the tracking feature
is utilized for g-ray pair event reconstruction. Here we present
TIGRE energy and angular resolutions, electron tracking measurements
and electronics readout system. The scientific objectives of TIGRE
on a long duration balloon flight or space mission will include high
resolution imaging of the diffuse 26Al and the annihilation radiation,
and also the search for other nuclear lines. Other objectives include
obtaining AGN and pulsar spectra and mapping of the Galactic continuum
diffuse emission.
