2pcs LYSO Scintillator Crystal for Gamma Radiation Scintillation Detector naitl

Description

This listing is for a quantity of 2 each per sale!!!
You get TWO
4X4X22mm
LYSO Crystals
with all sides Polished and ready to use. Many may come with some adhesive residue and/or PTFE reflective tape already wrapped around the long sides that can easily be removed if desired.  LYSO is a Premium Scintillator Material with very good energy resolution and guaranteed to work for radiation detection when coupled to a PMT and built into a probe. LYSO is denser than BGO or GSO with a specific density of 7.3 g/cc that provides excellent stopping power for high energy photons. Much greater density than that of NaI(Tl) and is non-hygroscopic and safe to handle. LYSO is very durable and does not break easily. LYSO contains Lutetium that is slightly radioactive itself, so you have a very specific background in this material. When measuring low energy samples, this background can be subtracted, but is not always necessary. These crystals sell new at a price of each, so this is a great bargain
since these perform just the same as new ones.
The demonstration pictures show peaks of several common energy sources without the background removed. The PMT used for the pictures is a Hamamatsu R9420 (available in another of my listings) using just a single crystal coupled with silicone to the center of the face and then wrapped with PTFE and black tape. Just a single crystal can be used to make a decent detector capable of gamma spectrometry at an unbelievable price. The Multichannel Analyzer (MCA) software used is Theremino, and is generously provided free of cost by the good folks at Theremino.com.
This would be a FANTASTIC price for only a single crystal, but you get a pair of crystals (2) for the price of this listing. Want even better pricing... see my other listings for LYSO Arrays. No additional shipping cost on multiple purchases of this item when crystals are purchased at the same time.
Dimensions each crystal:
Length = 22mm
Sides (both) = 4mm
Weight = 2.57gm
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 revolution.

Attention school teachers and students. These are excellent for science and physics projects, experiments and term or research papers. Scintillator detectors are fun and easy to build for all age groups from high school through college and university. Great experience and fun for the electronic hobbyist as well.
