摘要：

At the newly installed neutron scattering facility for the calibration of Dark Matter (DM) detectors we have measured quenching factors (QFs) at room temperature in NE 213 and NaI(Tl). For proton energies E-p between 1 and 3.5 MeV we found the electron-equivalent energy E-ee to obey the relation E-ee = (0.23 +/- 0.03)E-p + (0.02 +/- 0.01)E-p(2). The QF of the light output from Na recoils in NaI(Tl) at 850 keV was measured to be Q = 0.21 +/- 0.04. (c) 2006 Elsevier B.V. All rights reserved.
