Boulby Dark Matter Detectors
Activity at the Boulby FacilityThe ZEPLIN III dark matter experiment is continuing at Boulby, through second data run. Results from first run are now published (see next)
The DRIFT II dark matter experiment is supported by NSF. Recent visit by NSF (Jim Whitmore) very successful and awaiting extension funding for post 2012. Recent upgrade successful (see next).
The DRIFT III dark matter proposal underway.
SKY0 climate change experiment completed (cloud formation by cosmic rays). Next generation SKY-I experiment proposed for Boulby.
LAGUNA (50-1000kton neutrino physics) design study continues. Boulby is one of 7 European sites being considered (see next). Technical feasibility of cavern confirmed by AAE Ltd. mining consultants
Geo-physics and detector research projects also underway
Science at Boulby is strongly supported by the mine company CPL: There is an executive board that oversees this - Graham Clarke (CPL manager); Geof Tomlinson (Sheffield); David Petley (Durham Geophysics); Mike Cowling (Crown Estates); Sean Paling/Neil Spooner

Multi-panel 0.9μm thick DRIFT cathodecathode tested at full
voltage (32.5kV)
DRIFT II is now volume limited.... not background limited
No compromise on directional sensitivity needed to achieve this
DRIFTII SD LimitThis new SD llimit is achieved with no compromise on directional sensitivity (others experiments on plot do not have this)
this is ~x1000 better than any competitor directional WIMP detector
LAGUNA - new ramp complete
440 page design document completed for Boulby
New Ramp down into hard dolomite rock at 1200-1300m depth completed (this is 100-200m below the salt level of the Palmer lab)
ANSYS Geo-technical simulations by AAE Ltd. confirm technical feasibility of LAGUNA at Boulby
LAGUNA Cavern is Feasible at Boulby
Conclusion
We (including CPL) are waiting hopefully for STFC to honour commitment to interim support while we put in place alternative funding and new experiments.
Palmer lab operating costs are ~£300K/year (JIF/PPARC capital investment was £3.1M).
Decommissioning costs are high because of the need to remove all materials from the Palmer excavation for safety reasons.
Boulby continues to produce world leading science and is in demand (e.g. NSF, Danish agencies....)
