Towards a spatially resolving detector for ultra-cold neutrons — •Konrad Franz for the tauSPECT collaboration — Department Chemie, Johannes Gutenberg Universität Mainz
One of the challenges in ultra-cold neutron (UCN) detection is to convert the electrically inert neutron into an electrical signal. In the presented detector design this is achieved by employing a conversion layer stacked with a scintillation layer, in which the neutron induced α-particle generates a light pulse. This scintillation light is then guided onto an array of silicon photomultipliers (SiPMs). Spatial resolution can be achieved by reading out each SiPM individually. A main advantage of this setup is its compatibility with high magnetic fields, which allows for in-situ detection of UCNs in such environments. Combining spatial resolution with a magnetic field gradient enables UCN energy resolution.
The talk will give an overview of the detector design and will outline its advantages. Furthermore, the current status of the development will be presented and the main challenges moving forward will be discussed.
