Next Steps • Contractors • Finish Utility Area: Finish chiller assembly; piping to waste water plant; fire water lines to 6600L; commission chillers, STP. • Finish work in Experimental Areas: running water lines to Cube Hall and Cryopit; hook up electrics; Building Automation System; Fire Alarm. • SNOLAB • Fine cleaning of Personnel Area (showers, change rooms, lunch room, meeting room). • Fine cleaning of laboratory entrance (carwash, junction, access drift to SNO facilities). • Services including network Infrastructure, water pretreatment (relocation), up size 13kV power feed, ... Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Finish Line • Day 1 • Support Facilities: Enlarged personnel area and material handling facilities. • Experimental Spaces: Existing SNO Cavern, Cube Hall, Ladder Labs all operated as Clean Rooms. Cube Hall and Ladder Labs will be “bare rooms” but with nearby services. • Day 2 • Cryopit: Paint and fine clean. • South Drift: Remove old carwash and personnel facilities. Recover as experimental space. • Underground “clean room” machine shop. • Underground chemistry lab. Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Day 1 Infrastructure • Power Distribution • 2000 kVA capacity at 600V. 400A/600V services to the experimental areas except the Cryopit (deferred). Able to accommodate a future backup generator. Future Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Day 1 Infrastructure • Power Distribution Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Day 1 Infrastructure • Cooling • 300 T (1MW) Chiller; Chilled Water Loop: 250 PSIG, 5C. Distribution to SNO Utility, Cube Hall and Cryopit. CHILLER Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Day 1 Infrastructure • Ventilation • Main ventilation hard ducted. Distribution into Experimental areas with soft duct. 5-10 air changes per hour. HEPA filtered. Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Day 1 Infrastructure • Communications • Multimode 200 Mb/s capacity between surface and underground. 1 Gb/s off site. • Will complete a Gb/s single mode fibre link between underground and surface in the near future. Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Day 1 Infrastructure • Other Services • Industrial water, fire water, forced drain, compressed air. • Ultrapure water from the SNO water purification plant. • LN2 supplied by transport dewar from surface. • Low Background Counting • 1 existing HPGe Gamma Counter. Requesting funds for 2 additional counters. • Rn/Ra Emanation (Electrostatic Counters, Radon emanation. Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Staff • Staff of ~40 • Operations: Cleaning, material handling, maintenance, lab supervision. • Technical Support: Plant operations, chemistry, electrical, electronics, instrumentation. • Design: Primarily mechanical and process systems expertise. Design work, reviews. • Construction: Small construction group with expertise in the SNOLAB related issues. Assists with experiment installation. • IT: Networking, system administration. • Admin: Procurement, shipping and receiving, training. Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Experimental Program • The experimental program has concentrated on astroparticle physics but has also had submissions from other fields such as seismology and fundamental constants. • Requests for space are reviewed by the Experiment Advisory Committee (EAC) which makes recommendations to the Director. • To date 25 Letters of Interest or proposals have been submitted, 13 of which have been recommended by the EAC as appropriate for pursing for siting at SNOLAB. Of these 8 have developed mature plans to come to SNOLAB. Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Experimental Program Unallocated 2009: DEAP/CLEAN 3600, MiniCLEAN 360 Cube Hall Unallocated Cryopit Unallocated Utility Drift Phase III Stub Unallocated 2010: SuperCDMS Now:PICASSO-II Now:DEAP-1 Now:PUPS Ladder Labs Unallocated SNO Cavern South Drift 2009: SNO+ Personnel facilities • Experiments expected • to request space soon: • EXO 200 Gas • HALO • PICASSO-III Utility Area
Beyond Construction • With the laboratory almost complete, construction emphasis is shifting to facilitating the siting of experiments. • Cube Hall: Begin steel work for DEAP/CLEAN and MiniCLEAN. • SNO Cavern: Repair of liner floor and install of hold downs for SNO+. • SNO Utility Rm: Excavation of pit for SNO+ scintillator plant. • Renovation of South Drift, old Carwash, ...

Schedule 2008 2009 Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Summary • Construction is almost complete! • Ready to begin the installation of the Day 1 experiments. Civil work can being any time in the new laboratory areas. • We plan to install steel in the Cube Hall at the beginning of 2009. • Some space has been allocated for experiments but there is still significant room available. • SNOLAB is open for business.
