CsI(Tl) Scintillation Crystal
CsI(Tl) has a light output of 54 photons/keV and is one of the brightest scintillators known. It has most of its emission in the long wavelength part of the spectrum (>500nm), it is well-suited for photodiode readout.
CsI(Tl) has a very good stopping power, is slightly hygroscopic and with good plastic mechanical properties. Combined with a the relatively good radiation hardness properties, CsI(Tl) is also well suited for High Energy Physics. It also has no cleavage plane and is quite rugged – which makes it well-suited for well logging, space research or other applications where severe shock conditions are encountered.
