A High Vacuum End Cap Design for Use with Quartz Tubes

摘要

A new method for mating quartz tubes to metal flanges is outlined. The main goal was to minimize machining of the metal flange by using off-the-shelf commercial parts. The system is vacuum tight to Helium leak rates appropriate to an O-ring sealed system and, since the endcaps are bolted on, the design also allows for slight positive pressure applications
