CaF2 (Eu)

Summary

CaF 2 (Eu), Europium-doped calcium fluoride, is a low-density scintillation crystal with a highlight output. With its low Z value, it is well-suited for the detection of electrons (beta particles) with a high efficiency (low backscatter fraction). CaF 2 (Eu) is a crystal that is also used in phoswich scintillation detectors in combination with NaI(Tl).
