Hi Ken,
10-6 torr is about the the minimum vacuum that will be required in the
goniometer. The vacuum in the tagger will be in the 10-5 range and in
the accelerator upstream 10-7 torr range. This should work. Is there a
layout of the components combined to make the complete setup? We could
then start looking at mounting in a vacuum housing.
Thanks,
Tim
