4. Activity at the Boulby Facility The 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

6. Recent DRIFTII Upgrade Multi-panel 0.9μm thick DRIFT cathode cathode tested at full voltage (32.5kV)

7. DRIFT II is now volume limited.... not background limited No compromise on directional sensitivity needed to achieve this DRIFTII SD Limit This 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

8. DRIFT III Concept for Boulby

9. 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)

10. LAGUNA at Boulby GLACIER Liquid Argon Cavern Design completed by AMCO Ltd amd AAE Ltd. diamater 80m

11. ANSYS Geo-technical simulations by AAE Ltd. confirm technical feasibility of LAGUNA at Boulby LAGUNA Cavern is Feasible at Boulby

12. 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....)
