Fabrication of the PDX vacuum vessel

PDF Version Also Available for Download.

Description

The vacuum vessel for PDX is designed to meet the three goals of large volume, simplicity and accessability. A shell of one half inch thick welded 305 stainless steel meets these requirements. The geometry of the tank is that of a stretched torus having a cross sectional shape of a race track. Access to the inside of the tank is available through man sized ports, removal of top or bottom, or separation of the vessel into halves by a joint in the vertical plane. Evacuation is accomplished by either mercury diffusion pumps, backed by rotary mechanical pumps, or liquid Helium ... continued below

Both systems are being evaluated. (auth)
