Cristal scintillateur LYSO pour détecteur de scintillation de rayonnement gamma naitl

4X4X22mm LYSO Crystal  with all sides Polished and ready to use. 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 7.16 g/cm^3 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. Great for high-energy physics experiments. LYSO is very durable and does not break easily.  These crystals  typically  sell new at a price of $50 each . 

These are also great for use in calibration of a gamma spectroscopy system.  LYSO contains Lutetium Lu176 that is slightly radioactive itself, so you have a very specific background peaks in this material that make it very useful for calibration. When measuring low energy samples, this background can be subtracted, but is not always necessary. Since the activity is very low, they are not recommended for use as a Geiger counter check source.

This listing is for purchasing one or more individual pieces .  I have additional listings with larger quantities and multi-crystal arrays available.

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.

Dimensions each crystal:

Length = 22mm Sides (both) = 4mm Weight = 2.52gm

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.  

Physical Properties Of LYSO

The crystals may come with some slight adhesive residue that can easily be removed with a new straight edge razor blade.

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.
