LYSO crystal scintillators

Hi! Some time ago I’ve bought some 4x4x22mm LYSO Crystals to make a scintillation probe or just to test they.

From the manufacture:

LYSO crystal is an ideal generation scintillator crystal. LYSO (Cerium-doped Lutetium Yttrium Orthosilicate). LYSO crystal has the advantages of high light output and density, quick decay time, excellent energy resolution and low cost. These properties make LYSO an ideal candidate for a range of ray detection applications in nuclear physics and nuclear medicine, which require higher, improved timing resolution and superior energy resolution. “

The seller on ebay is the well know: “The Rad Lab”. For 12$ I’ve received 2 crystals. They are for sure intended to use into a proton emission tomography machine “PET”. More docs from Saint Gobain:

I think this crystals are from a PET machine who was scrapped… but hey, they works great! Take a look at how they react when are exposed to some UV light.
