چکیده

The neutron background at the underground laboratory at Boulby-a site for several dark matter experiments-is discussed. Special emphasis is put on the neutron background produced by cosmic-ray muons. The most recent versions of the muon propagation code MUSIC, and particle transport code FLUKA are used to evaluate muon and neutron fluxes. The results of simulations are compared with experimental data.

Dark Matter Search at Boulby Mine

The Boulby Dark Matter Collaboration (BDMC) is running a WIMP Dark Matter research programme in the underground laboratory of Boulby Mine. The two axes of the programme are based on (1) liquid Xenon (LXe) as the WIMP target and (2) directional detection in low pressure gas detectors. ZEPLIN-1 is a 3.1kg of LXe scintillation detector with a background discrimination based on Pulse Shape Analysis...

First measurement of low intensity fast neutron background from rock at the Boulby Underground Laboratory

A technique to measure low intensity fast neutron flux has been developed. The design, calibrations, procedure for data analysis and interpretation of the results are discussed in detail. The technique has been applied to measure the neutron background from rock at the Boulby Underground Laboratory, a site used for dark matter and other experiments, requiring shielding from cosmic ray muons. Th...

Dark Matter Experiments at Boulby Mine

The Boulby Dark Matter Collaboration (BDMC) is running several experiments for particle (WIMP) dark matter search in the Underground Boulby Laboratory. These include a liquid xenon detector (ZEPLIN I) and a low pressure gas TPC with directional sensitivity (DRIFT I). Next stage double-phase xenon detectors ZEPLIN II and ZEPLIN III, and a new TPC DRIFT II will be installed at Boulby in a few mon...

Reactor Antineutrino Signals at Morton and Boulby

Increasing the distance from which an antineutrino detector is capable of monitoring the operation of a registered reactor, or discovering a clandestine reactor, strengthens the Non-Proliferation of Nuclear Weapons Treaty. This report presents calculations of the reactor antineutrino interactions, from both quasi-elastic neutrino-proton scattering and elastic neutrino-electron scattering, in a ...

Limits on the spin-dependent WIMP-nucleon cross sections from the first science run of the ZEPLIN-III experiment.

We present new experimental constraints on the WIMP-nucleon spin-dependent elastic cross sections using data from the first science run of ZEPLIN-III, a two-phase xenon experiment searching for galactic dark matter weakly interacting massive particles based at the Boulby mine. Analysis of approximately 450 kg x days fiducial exposure allow us to place a 90%-confidence upper limit on the pure WI...
