Bachelor-, Master- and PhD-Thesis

TRD Integration and Testing

The AMS-02 TRD has been constructed in Aachen. It consists of 20 layers of straw modules and fleece radiator with a total of 328 modules (16 straws each). The housing consists of a conically shaped octagon structure made out of CFC-Al-honeycomb material and is closed by a lower and upper honeycomb plate. The gas is a 80:20 Xe=CO mixture. In the coming years we will test the TRD with cosmics and in beam tests and integrate it into the AMS-02 experiment at CERN. The offered Diploma-Thesis are focused on detector development and testing.

For PhD-Thesis we offer a three year position in our institute. The salary is according to BAT IIa/2.

Tracker Alignment System

AMS-02 particle tracking is based on 8 planes of double-sided Si detectors in a magnetic field of 0.8 Tesla. The position stability of the tracking elements will be controlled using infrared laser and cosmic straight tracks. The laser alignment system has been developed in Aachen. In the coming years we are responsible for the test of the flight hardware, the integration into the experiment at CERN and the operation during AMS-02 data taking on the ISS. The offered Diploma-Thesis are focused on detector development and testing.

Anti-Coincidence Counters

The AMS-02 silicon tracker is surrounded by scintillating counters, the Anti-Coincidence-Counters (ACC) to veto particles which are traversing the tracking volume from the side. The ACC have been developed and build in Aachen. In the coming years we are responsible for the test of the flight hardware, the integration into the experiment at CERN and the operation during AMS-02 data taking on the ISS. The offered Diploma-Thesis are focused on detector development and testing.

Search for Dark Matter

The nature of dark mater is one of the most important questions in fundamental physics. The neutralino is an excellent dark matter candidate. AMS-02 will measure cosmic ray electron and positron spectra with excellent precision. A discovery of an anomaly in the positron spectrum could be a clear indication for the annihilation of dark matter in our galaxy. The offered Diploma-Thesis are focused on MC-Studies and data analysis.
