Analysis of data from the DEAP-3600 dark matter detector

The DEAP dark matter detector has been taking physics data for 3 years, searching for interactions between galactic dark matter particles and the argon target material. This unique dataset spanning hundreds of TB offers many opportunities to study liquid argon scintillation physics, optical processes, and background suppression techniques. MSc and BSc topics related to background suppression through pulse shape analysis, Dark Matter signal modelling, and the study of rare coincidences, are available. Students work within an international collaboration of over 100 physicists and might have the opportunity to visit the detector site at SNOLAB in Canada. Students will acquire skills in data analysis and statistics, C++ and/or python programming, Linux/Unix command line operation, Monte Carlo simulation, and in working with large datasets on high performance computing systems. Students have the chance to practice communicating physics results to other students and experts from many different institutions by presenting their work in bi-weekly project-wide analysis phone-conferences.

Sensitive Tests der Eigenschaften von Wellenlängenschieber für dunkle Materie und neutrinolose Doppel-Beta-Zerfallsdetektoren

Rare event searches looking for neutrino and dark matter interactions are performed with highly sensitive detector systems, often relying on scintillators, especially liquid noble gases, to detect particle interactions. Detectors consist of structural materials that are assumed to be optically passive, and wavelength-shifting materials that absorb photons and re-emit them at wavelengths where their detection is more easy or efficient. MSc theses are available related to measuring the wavelength shifting efficiency of a number of materials that might be used in future detectors. Furthermore, measurements to ensure that presumably passive materials do not re-emit photons, at the low level relevant to the detectors, can be done. Part of the thesis work can include Monte Carlo simulations and data analysis for current and upcoming dark matter detectors, to study the effect of different levels of desired and nuisance wavelength shifting. In this project, students will acquire skills in photon detection, wavelength shifting technologies, vacuum systems, UV and extreme-UV optics, detector design, and optionally in C++ programming, data analysis, and Monte Carlo techniques.
The work will be done in the context of the DarkSide-20k/DEAP-3600 and LEGEND nternational collaborations. This work is done in close collaboration with institutions in Canada, Poland and in Italy with the option of visiting the collaborating institutions. Students have the chance to practice communicating physics results to other students and experts from many different institutions by presenting their work in bi-weekly project-wide phone-conferences.
