Liquid scintillator cells are containers, usually made of glass or aluminum, with at least one ground-and-polished port available for viewing by a photomultiplier tube (PMT). The scintillators are deoxygenated for improved stability and light output; and, the cells have expansion reservoirs containing oxygen-free nitrogen to maintain this condition.
Unless otherwise instructed, glass cells will be coated with a diffuse white reflector. Non-glass cells will have an internal white reflector. The reflector and construction materials are selected for long-term compatibility. Aluminum cells have a clear-anodized surface treatment.
