The DESY CMS group offers several projects for Bachelor, Master and PhD theses related to the following topics:

Outer Tracker Module Development (contact Andreas Mussgiller)

Measurements of thermal properties of novel materials, test structures and module prototypes

• characterization of composites
• optimization thermal interfaces
• refinement of thermal finite element analyse

Optical measurements of the deformation of test structures and prototype modules due to thermal stress final design and commissioning of the laboratory equipment

• optimization of the image recognition software
• improvement and extension of the reconstruction software
• realization of calibration measurements

Outer Tracker End Cap Mechanics (contact Andreas Mussgiller)

• development of a small end cap prototype
• optimization of the assembly procedure

Development of Radiation-hard Silicon Sensors (contact Doris Eckstein)

• calibration of Transient Current Technique (TCT) setup
• establish edge-TCT setup
• characterization of silicon test structures (diodes) using cooled probe station
• test beam measurements and analyses of irradiated and non-irradiated silicon sensors using an ALIBAVA setup
• investigation of sensor properties using TCT, multi-channel TCT and edge-TCT
• investigation of bulk damage in combination with surface damage of silicon sensors
