Experimental group for rare event searches – direct search for dark matter

The group for rare event searches, jointly run by TU Wien and HEPHY, is a member of the direct dark matter detection experiments CRESST and COSINUS, the neutrino experiment NUCLEUS, and the low-energy calibration effort CRAB. The group is heavily involved in data analysis and simulation for these experiments and develops their DAQ systems. The group is a member of the collaborative research center “Neutrinos and Dark Matter in Astro- and Particle Physics” www.sfb1258.de.

We are looking for a postdoctoral researcher (PostDoc) working on raw data analysis, software development, modeling of the response of cryogenic detectors and automation of detector operation for CRESST-III and future low-mass dark matter search experiments. 

Technology advances in low-threshold cryogenic detectors in the last decade opened up the search window to dark matter particles much lighter than 1GeV/c2. However, further improvements will require an even more detailed understanding of the detector response obtained from an electrothermal feedback model. This model can also be used to develop automation algorithms for the optimal operation of the detectors. Automation is paramount for next-generation cryogenic dark matter searches utilizing large arrays of cryogenic detectors combining low thresholds with large exposure. The successful candidate is expected to contribute to the setup of a new planned cryogenic facility in Vienna. Involvement in DAQ software and DAQ electronics is possible and will be appreciated. 

TASKS:

• Raw data analysis 
• Electrothermal feedback model which may include methods of machine learning
• On-site support at LNGS (Italy) 
• contributions to the setup of the new planned cryolab
• Participation in international conferences and summer schools (travel costs will be covered)
• Cooperation and day-to-day supervision of undergraduate students
• Optional: participation in hard and software development of the data acquisition system
