Possible Theses in the SiFi-CC Project

Ion therapy is a very precise tool in cancer treatment because of its characteristic longitudinal dose profile (Bragg peak). To optimize the precision of ion therapy, a real-time monitoring of the longitudinal Bragg peak position is needed. A promising approach towards online range verification in ion therapy is the analysis of prompt gamma radiation emitted by several nuclear processes. In our group a SiPMs and scintillating fiber-based Compton Camera (SiFi-CC) has been developed. This camera will record the prompt gamma radiation and will be able to reconsturct the position of the bragg peak. The project is a close international collaboration  with the Jagiellonian University Krakow as well as the University of Katowice (Poland).

On the SiFi-CC project, we offer master and bachelor theses on request. Topics include

  • data analysis and
  • simulation.

Most of the theses include parts from more than one of these areas. Specific subjects are presented at the Tag der Physik.


Data Analysis

We develop an analysis and evaluation framework based on simulation of the SiFi-CC. This framework includes all steps that are necessary to extract the Bragg peak position from the data that a real detector would deliver. Your task would be to implement a neuronal network for the event identification and to compare the resulting event classification with the current one. Another task would be to apply the principle of a Single Plane Compton Camera to the two modules of the SiFi-CC and to extend the reconstruction with the so gained information.



For all our experiments a simulation in Geant4 is performed for a better understanding and comparison of measurement results. Additionally it is a good possibility to plan and optimize detectors.

Your task could be to extant the simulation of the SiFi-CC by an active vetodetector or a passiv shield or to determine the secondary radiation of a patient via a detailed simulation of a human body. Furthermore you could explore the feasibility to use a tracer that accumulates in the tumor to enhance the prompt gamma production or to produce characteristic energy lines. Geant4 is based on C++, so it is advantageous if you have some experience with it.
