LaCl3(Ce) - Lanthanum Chloride (Ce) Scintillator Crystal

LaCl3(Ce) - Lanthanum Chloride - is a salt compound of lanthanum and chlorine and one of a new generation of inorganic scintillator based gamma radiation detectors. LaCl3(Ce) scintillators have fast light output decay times provide excellent energy resolution performance.

LaCl3(Ce) scintillator crystals have:

Fast decay times - 28nsec
High light outputs - 49,000 Photons/MeV
The capability to achieve excellent Energy Resolution (e.g. c.3.8%@662keV, 1″ Dia./1″ Long)
Optical outputs with good linearity with temperature
The capacity to deal with high count rates
Excellent radiation hardness

LaCl3(Ce) scintillator crystals - issues to be aware of:

Hygroscopic and therefore requires encapsulation

LaCl3(Ce) scintillator crystals are useful for applications suchas:

Security - cargo inspection
Medical - SPECT
Industrial - Well logging
Nuclear and high energy physics - specialist applications
