Earth Flyby and Pioneer Anomalies (2008)

Gerrard, M. B., Sumner, T. J.

Applying Newtonian dynamics in five dimensions rather than four, to a universe that is closed, isotropic and expanding, suggests that under certain circumstances an additional and previously...

Measurements of neutrons produced by high-energy muons at the Boulby Underground Laboratory (2008)

Araujo, H. M., Blockley, J., Bungau, C., Carson, M. J., Chagani, H., Daw, E., ...

We present the first measurements of the muon-induced neutron flux at the Boulby Underground Laboratory. The experiment was carried out with an 0.73 tonne liquid scintillator that also served as an...

Odyssey: a Solar System Mission (2007)

Christophe, B., Andersen, P. H., Anderson, J. D., Asmar, S., Bério, Ph., Bertolami, O., ...

The Solar System Odyssey mission uses modern-day high-precision experimental techniques to test the laws of fundamental physics which determine dynamics in the solar system. It could lead to major...

Measurement of single electron emission in two-phase xenon (2007)

Edwards, B., Araujo, H. M., Chepel, V., Cline, D., Durkin, T., Gao, J., ...

We present the first measurements of the electroluminescence response to the emission of single electrons in a two-phase noble gas detector. Single ionization electrons generated in liquid xenon are...

Improved Simulation of the Mass Charging for ASTROD I (2007)

Bao, Gang, Ni, Wei-Tou, Shaul, D. N. A., Araujo, H. M., Liu, Lei, Sumner, T. J.

The electrostatic charging of the test mass in ASTROD I (Astrodynamical Space Test of Relativity using Optical Devices I) mission can affect the quality of the science data as a result of spurious...

Track Reconstruction and Performance of DRIFT Directional Dark Matter Detectors using Alpha Particles (2007)

Burgos, S., Forbes, J., Ghag, C., Gold, M., Kudryavtsev, V. A., Lawson, T. B., ...

First results are presented from an analysis of data from the DRIFT-IIa and DRIFT-IIb directional dark matter detectors at Boulby Mine in which alpha particle tracks were reconstructed and used to...

First Results from the DRIFT-IIa Dark Matter Detector (2007)

Burgos, S., Forbes, J., Ghag, C., Gold, M., Kudryavtsev, V. A., Lawson, T. B., ...

Data from the DRIFT-IIa directional dark matter experiment are presented, collected during a near continuous 6 month running period. A detailed calibration analysis comparing data from gamma-ray,...

First limits on WIMP nuclear recoil signals in ZEPLIN-II: a two phase xenon detector for dark matter detection (2007)

Alner, G. J., Araujo, H. M., Bewick, A., Bungau, C., Camanzi, B., Carson, M. J., ...

Results are presented from the first underground data run of ZEPLIN-II, a 31 kg two phase xenon detector developed to observe nuclear recoils from hypothetical weakly interacting massive dark matter...

Reply to: Critical revision of the ZEPLIN-I sensitivity to WIMP interactions (2007)

Smith, N. J. T., Murphy, A. S., Sumner, T. J.

Recent objections (Phys.Lett. B 637, 156) to the published Zeplin I limit (Astropart. Phys 23, 444) are shown to arise from misunderstandings of the calibration data and procedure, and a misreading...

Sensitivity of the icecube detector to astrophysical sources of high energy muon neutrinos (2004)

Ahrens, J., Bahcall, John N., Bai, X., Bay, R.C., Becka, T., ...

We present the results of a Monte-Carlo study of the sensitivity of the planned IceCube detector to predicted fluxes of muon neutrinos at TeV to PeV energies. A complete simulation of the detector...

Study and suppression of anomalous fast events in inorganic scintillators for dark matter searches (2003)

Kudryavtsev, V.A., Spooner, N.J. C., Lightfoot, P.K., Roberts, J.W., Lehner, M.J., Gamble, T., ...

The status of dark matter searches with inorganic scintillator detectors at Boulby mine is reviewed and the results of tests with a CsI(Tl) crystal are presented. The objectives of the latter...

The NAIAD experiment for WIMP searches at Boulby mine and recent results (2003)

Ahmed, B., Alner, G. J., Araujo, H., Barton, J. C., Bewick, A., Carson, M. J., ...

The NAIAD experiment (NaI Advanced Detector) for WIMP dark matter searches at Boulby mine (UK) is described. The detector consists of an array of encapsulated and unencapsulated NaI(Tl) crystals with...
