Status: Off Site, Laurentian University

Off site radio-isotope lab will be located at Laurentian University.

Will include

Ultra Pure Water installation

Low BG counting alpha, ESCs (ElectroStatic

Counters) Ready September


Status: Underground

Excavation has proceeded slower than originally forecast

Complexity of excavation in some areas Coordination with maintaining the running SNO

experiment. The usual types of delays (cage down, power

failures etc). These delays were not unexpected and are a

normal part of mine excavation.

Experiment Space

Status: Outfitting Outfitting design is complete and has

gone to tender.

Costs are higher than expected

Very expensive time to be doing construction, let alone in a mine.

Will implement a phased approach to outfitting, priorities being:

1) New Personnel and Entry Facilities

2) Ladder Labs, Rectangular Hall

3) South Drift (old personnel facilities)

The larger experimental spaces in the Ladder Labs and Rectangular Hall will initially be less extensively outfitted than originally intended.

Completion of the outfitting will be done in the operations phase.


Nickel Price

Nickel Price

Outfitting is expected to begin late 2006 or early 2007

Operating Funds

The CFI award to construct SNOLAB did not include long term operating funds. (Operating funds were only included for construction phase.)

Extrapolating from the existing SNO operations expenses we anticipate the need for a $6M budget.

We are developing a mixed agency funding strategy involving federal and provincial agencies.

Have met with positive responses from the agencies in question.

Summary of Construction Status

Excavation

Phase I 76% complete. Rectangular Hall is the remaining major excavation.

Completion Spring 2007

Phase II Expecting decision within two months

If approved this fall, completion Fall 2007

Outfitting

Expected to begin late 2006

Completed (depending on Phase II) end of 2007 or early 2008

Beneficial occupancy

End of 2007 (experiment fit up could start several months earlier)

Bottom Line: In 2008 there will be 27,500 sq ft (PI) or 34,300 sq ft (PI+PII) of class 2000 cleanroom space available for experiments.


SNOLABOPERATIONS

andORGANIZATION

SNOLAB Organization We are transitioning from

SNO (an experiment with a lab) to SNOLAB (a lab with experiments)

Due to the different funding sources we have been intentionally keeping the SNO and SNOLAB operations independent.

As SNO sunsets most of the operations at the site will be conducted through SNOLAB.

We are still developing the SNOLAB organizational structure.

Organization Summary SNOLAB's Scientific Structure is intended to provide

mechanisms to:

Evaluate experiments;

Communicate the needs of experiments to the lab;

Communicate the abilities of the lab to the experiments.

SNOLAB's Operational Structure is intended to provide resources and expertise to facilitate the successful deployment of an experiment at SNOLAB.

These are evolving entities that will continue to change as the needs of these unique experiments become known.


Conclusions

Construction Status

Beneficial Occupancy for experiments end of 2007 with the possibility of limited early space.

Operations

Operational and scientific organization coming together.

Now is the time to develop technical proposals for deploying experiments at SNOLAB.
