“…In order to evaluate the total energy partition between the electronic and nuclear components for an impinging recoil of a given energy (Lindhard's partition function [81]), the whole cascade must be taken into account. In spite of all difficulties, the LSS theory provides a useful framework and describes reasonably well the energy losses by nuclear recoils, at least in what the scintillation efficiency of LXe is concerned (see [82,78]). We recommend [78] for a concise analysis of Lindhard's model and more recent works related to it, in view of WIMP detection with liquefied noble gases.…”

Liquid noble gas detectors for low energy particle physics

We review the current status of liquid noble gas radiation detectors with energy threshold in the keV range, which are of interest for direct dark matter searches, measurement of coherent neutrino scattering and other low energy particle physics experiments. Emphasis is given to the operation principles and the most important instrumentation aspects of these detectors, principally of those operated in the double-phase mode. Recent technological advances and relevant developments in photon detection and charge readout are discussed in the context of their applicability to those experiments.

a b s t r a c t XENON10 is an experiment designed to directly detect particle dark matter. It is a dual phase (liquid/ gas) xenon time-projection chamber with 3D position imaging. Particle interactions generate a primary scintillation signal (S1) and ionization signal (S2), which are both functions of the deposited recoil energy and the incident particle type. We present a new precision measurement of the relative scintillation yield L eff and the absolute ionization yield Q y , for nuclear recoils in xenon. A dark matter particle is expected to deposit energy by scattering from a xenon nucleus. Knowledge of L eff is therefore crucial for establishing the energy threshold of the experiment; this in turn determines the sensitivity to particle dark matter. Our L eff measurement is in agreement with recent theoretical predictions above 15 keV nuclear recoil energy, and the energy threshold of the measurement is $4 keV.A knowledge of the ionization yield Q y is necessary to establish the trigger threshold of the experiment. The ionization yield Q y is measured in two ways, both in agreement with previous measurements and with a factor of 10 lower energy threshold.

“…However, it is necessary to introduce the electronic LET (LET el = -d/dx) for very slow ions since S T = S n + S e (Hitachi, 2005(Hitachi, , 2007. In other words, LET el is the specific electronic energy loss along the track of charged particle.…”

Bragg-like curves, the electronic energy deposition as a function of the projected range, for recoil ions in N 2 , CO 2 , CF 4 and CS 2 are presented. The curves are intended for directional search for the dark matter candidate, WIMPs, using the gas TPC. Nuclear quenching factors for very heavy ions produced in -decay in dry air, N 2 , CO 2 , CF 4 and CS 2 are also estimated and compared with experimental values.
