Description: 100 pieces of 6X4X20mm GSO (Ce) Crystal Pixel, or Gadolinium Silicate, Gd2SiO5(Ce), also known simply as GSO. Each pixel has one small face smooth polished, and the sides and other face are prefinished with a texture to provide best internal reflection, especially when wrapped in a reflective material like PTFE Tape. GSO is a Premium Scintillator Material and guaranteed to work for radiation detection when coupled to a PMT and built into a probe. GSO is dense, with a specific density of 6.71 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. GSO is very durable and does not break easily. These crystals typically sell new at a price of $50 each. Dimensions each crystal:Length = 20mm Sides = 6mm X 4mm Weight = 3.22gm From the Manufacture:GSO Scintillation crystals are materials that emit light when exposed to ionizing radiation, making them useful for a wide range of applications, including radiation detection, medical imaging, and nuclear physics. GSO (Ce-doped Gadolinium Silicate) scintillation crystal or Ce:GSO. Ce:GSO is a type of inorganic scintillator that is widely used due to its high light output, fast decay time, and good radiation hardness. This crystal is made by doping Gadolinium Silicate (GSO) with a small amount of Cerium (Ce) to enhance its scintillation properties. Ce:GSO scintillation crystals are commonly used in gamma-ray detectors, positron emission tomography (PET) scanners, and other radiation imaging applications due to their high performance and reliable response to ionizing radiation.

This listing is for purchasing one or more individual pieces. If interested in larger quantities or multi-crystal arrays, please contact seller. The demonstration pictures show Cs137 peaks without the background removed. The PMT used for the pictures is a Hamamatsu R647 using just a single crystal coupled with silicone to the center of the face and then wrapped with PTFE and black shrink-wrap. 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. The PMT, Computer and other items shown are only to demonstrate the functionality of the crystal and are not included in the listing. I have tons of other radiation detection related equipment listed, so please check out my other items. I am always adding new items in this category, so please don't forget to add me to your favorites list and come back often! 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.
