A modification on documents D1900114 and D1900116 is on the works, and the changes will be modified by Don, as soon as he has the time. This new change is required because we need a one port for the Air Purge Valve at HAM7. This valve will help to bring the Chamber to room conditions -not under pressure-. Squeezer Tip-Tiilts that are located on D6 Flange (IC1, IC2) will change their location to D8 Flange, which is located at the top of the chamber. D8 will be a flange with 12 dsubs with 25 pins each.
