New Technique for the Measurement of the Scintillation Efficiency of Nuclear Recoils

We present a new technique developed for the measurement of the scintillation efficiency of nuclear recoils in solid scintillators. Using this technique we measured the quenching of the scintillation efficiency for the various recoiling nuclei in CaWO4 crystals which are used in direct Dark Matter searches.Comment: Preprint accepted for publication in NIM
