Abstract
The prototype TIGRE Tracking and Imaging Gamma-Ray Experiment is being prepared for a scientific balloon flight in fall, 2006. TIGRE is a Compton telescope for 0.5-10 MeV gamma rays and a pair telescope for 10-100 MeV gammas. It uses multiple layers of thin silicon strip detectors as both the Compton and pair converter and the charged particle tracker. The event coincidence requirement is completed with arrays of CsI(Tl)-photodiode detectors surrounding the converter/tracker and large Na(Tl)-PMT detectors below. The purpose of this flight is to demonstrate the background suppression capabilities of the TIGRE instrument with Compton recoil electron tracking and the improved angular resolution for pairs with silicon as the converter material. Details of the control and readout of the detectors will be described. Calibration results using laboratory radioisotopes will likewise be presented.
