ZEPLIN-III SSR EXTENSION

Lead Research Organisation: Imperial College London
Department Name: Dept of Physics

Abstract

This proposal will enable the extension of the ZEPLIN-III dark matter search to March 2011 in order to exploit fully the second science run now under way at Boulby. The instrument has been upgraded with a new array of low-background photomultipliers and a new anti-coincidence veto system surrounding the target. In addition, the underground operation has been largely automated, bringing about a gain in data quality as well as a decrease of the resources required to run the experiment. ZEPLIN-III is collecting high quality WIMP-search data and is performing extremely well. This extension will allow ZEPLIN-III, one of a very small number of instruments taking data around the world in 2011, to push further into unexplored WIMP parameter space, at a time when both the LHC and indirect dark matter serches are reaching a comparable level of readiness for discovery of the mysterious dark matter.

Description This award allowed us to conclude the second science run of the ZEPLIN-III experiment; this was the longest continuous run of a two-phase xenon detector at that time; this demonstrated that this technology (which has been at the forefront of dark matter detection for almost a decade) was stable enough to produce long datasets with high quality.

From this run, which spans several awards, we published competitive WIMP scattering exclusion limits, including world-leading spin-dependent limits.

We trained a significant number of students and postdocs who became experts in this technology and then moved on the XENON, LUX and LZ experiments.
Exploitation Route Many techniques which we developed were promptly applied to the LUX and XENON programmes which are on-going: in design, calibration, data analysis, simulations and detector operations. The suite of technical papers from ZEPLIN-III is extensively cited partly for this reason.

Description By the scientific community and the media. Some benefits resulted in other areas. For example, the vertex reconstruction algorithm developed for ZEPLIN-III (Solovov 2012) is being applied in Nuclear Medicine to gamma-camera calibration and reconstruction by our Portuguese colleagues.
