It's potentially an increase in size, possibly generated by the fact that the scale of these experiments in the areas of both dark matter research and neutrinoless double-beta decay may be larger than the cavities that presently exist.
I think there are a couple of stages that could be accommodated within the existing facility, but over the next five to 10 years there need to be plans made, because basically the world is saying that this is the place they want to come for these frontier experiments. They are, in a sense, the other half of the sorts of things that are being studied at these major billion-dollar accelerator facilities around the world. Canada has an opportunity to step forward with support for SNOLAB to attract the world and significantly large experiments, which may within the next five years or so require an expansion.
