stilbene single crystal

right photographs show some examples of stilbene single crystal, 50mm (dia) x 5mm (t) disc, and 5mm cube shape element

2 inch cubic shape or 2 inch dia x 2 inch tall cylinder shape is the available maximum size
stilbene in PVT matrix

custom made stilbene element, which is crashed stilbene particles suspended in PVT base plastic scintillator matrix, is available

a couple of examples are shown in right photographs
