Yes, that’s one of the papers that shows their little chamber. I believe it’s mentioned in a couple of other places. Die cast boxes work pretty well for the enclosures. If you want to zero the gradient in the inner enclosure, put a small fan in there. That adds it’s own issues so it’s probably not really something you want to do.
