Elton,
    It sounds like that since the gas selected defines the Cerenkov
detector, the choice of gas should definitely be an item of discussion
at the meeting in September.

As of January this year, there was only a single vendor on the planet. The
contact info is as follows. We will need to purchase gas in FY2005,
perhaps if we make a larger order we can get a better price. In any case,
the long term supply may be uncertain. The price quote at that time was
$99,000 per 1000kg.
