The development of germanium Compton telescopes for nuclear
-ray astrophysics (
new event reconstruction techniques to accurately determine the
initial direction and energy of photon events,
as well as to consistently reject background events.
This paper describes techniques for event reconstruction, accounting
for realistic instrument/detector performance and uncertainties.
An especially important technique is Compton Kinematic Discrimination,
which allows proper interaction ordering and background rejection with
high probabilities. The use of these techniques are crucial for the
realistic evaluation of the performance and sensitivity of any
germanium Compton telescope configuration.
