Since more than 100 years gaseous radiation detectors play an important role in the instrumentation of particle physics experiments as they offer certain properties which can not be achieved with other technologies.
In particular for a low-material budget and a good spatial resolution, which are essential for high-resolution tracking of charged particles and high momentum resolution along a bended trajectory in a magnetic field, gaseous detectors are the preferable choice.
The group conducts both basic research in the field of scintillation detectors with SiPM readout and development of such detectors for the needs of particle physics experiments, muon spin rotation, and neutron scattering instrumentation at PSI.
In particular for high time-resolution detection of charged particles in the presence of magnetic fields SiPM-based scintillation detectors are the only choice.
In order to cope with the demanding requirements for the construction of particle detectors the group has acquired experience and developed tools and methods to deal with tiny structures, to work under clean conditions, to design and construct stable low-mass structures, to achieve high-quality surface treatment of scintillators and to glue optical components.
