Sumner, T.J. et al. (2007) The ZEPLIN III Detector; Results from Surface Calibrations. Nuclear Physics B - Proceedings Supplements, 173. pp. 108-112. ISSN 09205632

ZEPLIN-III is a direct dark-matter search instrument using liquid xenon as a target.Both the scintillation light and the ionisation charge are measured.The instrument has been built and it is currently being testing in a surface laboratory.We present results from some of the initial testing, including design thermal control system verification, photomultiplier calibration (including spectral measurements with 60 keV photons from 241Am) and two-phase operation showing simultaneous measurement of scintillation and charge and position reconstruction.
