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.

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.
