Rick is correct in the fact that thick material is needed for a vessel to withstand vacuum inside and atm pressure outside.
Most industrial chambers will be of round section with dished ends and manufactured by a pressure vessel manufacturer. Remember that welded seams and joints on a vacuum vessel should be only on the inside surface to eliminate trapped volumes and crevices where contaminants can build up. No double sided welds or leak testing will be very difficult.
