Abstract
LUX-ZEPLIN (LZ) is a Dark Matter experiment based at the Sanford Underground Research Facility in South Dakota, USA. It is currently under construction and aims to start data taking in 2020. Its computing model stipulates two independent data centres, one in the USA and one in the UK. Both data centres will hold a complete copy of the experiment’s data and are expected to handle all aspects of data processing and user analysis. Here we discuss the set-up of the UK data centre within the context of the existing UK Grid infrastructure and show that a mature distributed computing system such as the Grid can be extended to serve as a central data centre for a reasonably large non-LHC experiment.
Highlights
The LUX-ZEPLIN (LZ) experiment [1] grew out of a collaboration of the completedLUX [2] and ZEPLIN [3] experiments
Its primary objective is the search for high mass weakly interacting massive particles (WIMPs)
GridPP [4] is a collaboration of 19 UK institutes providing computing resources (CPU and storage) to particle physics and related experiments in the UK
Summary
The LUX-ZEPLIN (LZ) experiment [1] grew out of a collaboration of the completed. LUX [2] and ZEPLIN [3] experiments. The resulting LZ collaboration consists of about scientists in 37 institutions mainly in the US and the UK, and Portugal, Russia, and Korea. Its primary objective is the search for high mass weakly interacting massive particles (WIMPs). The LZ detector is based around a 7-tonne liquid xenon volume and is currently being constructed ∼1.4 km underground in a disused mineshaft at the the Sanford. Data taking is scheduled to start in 2020
