    Abstract: An ultra-high vacuum chemical vapor deposition reactor which utilizes only single large diameter, quartz to metal ultra-high vacuum seal or a water cooled "Viton" seal, which is present at a first end of the reactor tube. The other end of the reactor tube has a substantially reduced diameter, and an ultra-high vacuum seal of correspondingly reduced diameter is used at this end. The pumping apparatus and the load station are both located at the first end of the apparatus to provide a single-ended operation. This arrangement obviates problems encountered in the prior art which required the use of two ultra-high vacuum quartz to metal seals at respective ends of the reactor.
