Novel Solutions for Challenging Problems

Europium-doped Strontium Iodide, SrI2(Eu)

Europium-doped Strontium Iodide (SrI2(Eu)) gamma detectors have a very high light output ranging from 80,000-100,000 ph/MeV and energy resolutions of about 2.8% at 662 keV, much better than the incumbent NaI(Tl) and CsI(Tl) scintillators. To date, availability of SrI2(Eu) detectors has been severely limited by the fracture of the crystal during crystal growth, resulting in low yield and high prices.

CapeSym's proprietary crystal growth process has overcome the fracture problem and is now routinely producing up to 2-inch diameter crystals. CapeSym's patent-pending process is based on decades of experience in crystal growth, crystal growth process simulation, and fracture mechanics.

Standard SrI2(Eu) sizes include:

  • 1 cm dia. x 1 cm
  • 1 in dia. x 1 in
  • 1.5 in dia. x 1.5 in
  • 2 in dia. x 2 in
  • Cuboids and other custom sizes are available, bare or encapsulated, with or without coupling to a PMT.
