PhD Research Topic

Working on dual-phase xenon time projection chamber (TPC) research within the XENON and XLZD collaborations.
Preliminary title: Dark Matter search with the upgraded XENONnT experiment
Start date: 2025 Dec (master thesis student: 2024 Aug – 2025 Sep)
Supervision: Prof. Dr. Kathrin Valerius

Detailed working topics:

  • Commissioning of the upgraded XENONnT experiment
    • Electric field simulations
    • Processing and analyzing detector data
  • Background investigation
    • Clusters of delayed electron extraction, so-called e⁻-burst
    • Spurious events from electrodes and accidental coincidences
  • R&D towards the next generation dual-phase xenon TPC with a focus on electrode design
    • Electrode manufacturing
    • Test setups for electrode inspection
