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.

该提案将使Zeplin-III暗物质搜索的范围扩展到2011年3月，以便完全利用Boulby正在进行的第二次科学运行。该仪器已通过新的低背景光电层面和目标围绕目标的新的反固定否决系统进行了升级。此外，地下操作在很大程度上是自动化的，从而带来了数据质量的提高，并减少了运行实验所需的资源。 Zeplin-III正在收集高质量的WIMP搜索数据，并且表现非常出色。这一扩展将使Zeplin-III（在2011年在世界各地获取数据的少数工具之一），在LHC和间接暗物质Serch均达到了可比的准备水平以发现神秘的暗物质的情况下，将进一步推向未开发的WIMP参数空间。
