The scintillation and ionization yield of liquid xenon for nuclear recoils

Abstract: 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… Show more

“…The largest non-background signals may be attributed to the largest nuclear recoil energy produced by the selected fluorescence state in an end-point measurement. Going one step further, the theoretical distribution of nuclear recoil energies produced by the target resonance could be folded into analysis of the non-background signals in a similar manner to broad-spectrum neutron scatter measurements [6]. High efficiency background rejection would require detailed background characterization with beam on-and off-resonance in addition to selective triggering of the DAQ and post-processing cuts on quantities such as energy, position, and event shape.…”

“…For this purpose the scintillation efficiency (L e f f ) and ionization yield (I.Y.) of nuclear recoils have been reported in candidate detector materials [4][5][6][7][8][9][10][11][12] (see Table I). Of the reported measurements only two [11,12], have probed recoils below one keV, both in Ge.…”
