Student Opportunities

The Compressed Baryonic Matter (CBM) experimental group at GSI (Darmstadt, Germany) proposes two PhD positions with the Goethe University of Frankfurt in the domain of heavy ion and detector physics.

 

CBM is part of the large international FAIR project with participant institutions in Germany, Russia, India, Poland and other countries. The aim of the CBM experiment is the exploration of the phase diagram of strongly interacting matter in the region of high densities and moderate temperatures. CBM is expected to deal with beam-target interaction rates up to 10 MHz collecting an unprecedented number of events in the heavy ion physics domain.

 

The CBM group at GSI is mainly involved in the design of the Silicon Tracking System (STS), data acquisition, and development of tracking and reconstruction algorithms. About 30 researches, including post-docs and PhD students, are currently participating in the preparation of the experiment. The successful candidate will be involved with the production of the silicon micro-strip detectors, performing the development, tests and evaluation of the assembled modules. Possible activities include tests with radiation sources and cosmic muons, infrared laser and electrical characterization of sensors and micro-cables with a needle probe station, as well as in-beam tests with a realistic setup at the SIS18 accelerator at GSI. Obtained results will be validated with simulation studies.

 

Another possible activity is the development of the tracking algorithms for the CBM experiment, particularly for the STS detector. Taking into account continuous beam operation mode, the reconstruction should deal with the time information, resulting in the complex 4D tracking approach. Due to the absence of simple hardware signatures, event selection in CBM involves the full reconstruction of the events. Thus the reconstruction algorithms have to be fast, robust, and heavily employ parallel computing features.

A Master or Diploma degree in physics, electronic engineering, computer science or other related discipline qualifying for research at GSI is required for application. An application should include a cover letter, CV and at least two reference letters. Review of applications will begin on April 8 2018, and continue until the position is filled.
