Abstract

Outgassing measurements of three UHV materials (304 Stainless Steel (SS), 316L SS and 6061T-6 aluminum) were made using the conductance and accumulation techniques as given in the AVS Recommended Practice for Outgassing Measurements [ ]. Measurement results indicate good agreement between the two techniques. This study was undertaken to help determine the vacuum limitations of the photoelectron guns used at Jefferson Lab and to aid in the choice of vacuum chamber materials that will be used in the construction of future photoelectron guns. The outgassing rate measured for all of the chamber materials, regardless of technique, was about 1 X 10{sup -12} Torr{sup -}l/s{sup -}cm{sup 2}.

Characterization of the CEBAF 100 kV DC GaAs Photoelectron Gun Vacuum System

Journal Article Stutzman, M; Adderley, P; Brittian, J; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

A vacuum system with pressure in the low ultra-high vacuum (UHV) range is essential for long photocathode lifetimes in DC high voltage GaAs photoguns. A discrepancy between predicted and measured base pressure in the CEBAF photoguns motivated this study of outgassing rates of three 304 stainless steel chambers with different pretreatments and pump speed measurements of non-evaporable getter (NEG) pumps. Outgassing rates were measured using two independent techniques. Lower outgassing rates were achieved by electropolishing and vacuum firing the chamber. The second part of the paper describes NEG pump speed measurements as a function of pressure through the lower partmore »« less

Radiation cleanup of vacuum systems (radiation-induced outgassing). Final report, September 15, 1976--November 14, 1977

Technical Report Anno, J.

A stainless steel-304 vacuum system has been designed and constructed to study radiation-induced outgassing when this material is exposed to cobalt-60 gamma radiation. The system is pumped with an ion pump and sorption roughing pump. No foreign materials have been introduced except for copper seals at the flanges. An analytical model has been developed which predicts the outgassing from SS-304 to be 8.27 x 10/sup -12/ torr-liters/(cm/sup 2/) (sec) per megarad/hr. Extrapolation of existing data for aluminum suggests a lower value of 1.0 x 10/sup -12/ torr-liters/(cm/sup 2/) (sec) per megarad/hr. Experiments determined the value for stainless steel-304 after bakeoutmore »« less

Measurement of Ultra Low OutGassing Rates for NLC UHV Vacuum Chambers

Technical Report Eriksson, Leif

Ultra low outgassing rates would be highly advantageous in accelerators and storage rings, such as the Next Linear Collider (NLC), where an outgassing rate of <10{sup -12} Torr liter/sec/cm{sup 2} could eliminate the need for costly distributed pumping. Measuring such low outgassing rates at room temperature has many difficulties. However, by inspection of Fick's law, it can be seen that thermal desorption is proportional to outgassing rate. It is commonly observed that the outgas rate doubles approximately every 15 C for temperatures under 100 C. By measuring outgassing rate versus temperature and time and extrapolating back to room temperature wemore »« less
