Investigation of PEN light emission as fct. of synth. and molding

understanding of light emission processes, theory and simulation
* What are the parameters we need to understand
* Define dimension for standard testing - comparability
* Surfaces
* Detection methods
- Sources: UV light and radioactive sources
- Spectrometer
- SiPMs
- Available test stands
- What test stands do we want?
- in LAr?
* Coupling of detectors to arbitrary forms --> Simulations

Convener: Naomi van der Kolk (MPI für Physik)
