In-Beam Test of the TIGRESS Prototype Detector

Abstract

<p>This thesis describes the preparations for the first in-beam test of a new type of gamma-ray detector, which will be part of the TIGRESS array of segmented high-purity Germanium clover detectors.</p> <p>Gamma rays emitted from a moving nucleus are Doppler-shifted leading to a broadening of the measured photo-peak. Through a determination of the interaction position in the crystal, it is anticipated that most of the resolution may be recovered with these detectors. In order to test this prediction, the detector has been tested in an experiment. Prior to this test, a "pre-test" was done with a conventional detector. The reasons for the choice of the reaction for the pre-test, the description of the experiment and its results and the lessons learned will be presented.</p>
