Development of an Electron Backscattering Detector for PERC

PERC (Proton Electron Radiation Channel) is a new neutron decay facility that is currently being constructed at the FRM II research reactor. PERC is a versatile source of decay electrons and protons and allows the measurement of several correlation coefficients of the neutron decay with an order of magnitude improvement in precision over current experiments. Measurements of these coefficients are a sensitive probe to investigate the mechanisms of the weak interaction.

The core component of PERC is an 8 m long superconducting magnet. Electrons and protons produced by neutrons decaying inside the magnet are guided along the magnetic field lines to the main detector system behind the spectrometer. Our group has previously used scintillator-based electron detectors for precision measurements of neutron decay correlations. Building on this experience, we plan to use similar devices to detect backscattering in PERC. The purpose of these backscattering detectors is to identify events where the decay electron only deposits a fraction of its energy in the main detector.

The objective of this thesis is the design and demonstration of the backscattering detectors for PERC, including the development of a new read-out system for electron spectroscopy with plastic scintillators and silicon photomultipliers (SiPMs).

Tasks

  • Familiarize yourself with neutron decay studies and particle-tracking simulations.

  • Optimize the design of the backscattering detectors for PERC based on simulation data.

  • Develop and test a SiPM-based read-out system for plastic scintillators suitable for precision electron spectroscopy.

  • Construct and test a prototype of the backscattering detectors.

What we offer

We offer you an interesting opportunity to participate in the development of a new high-profile experiment, allowing you to gain diverse experiences in the fields of detector physics, electronics, and low-energy particle physics!
