ULTRA HIGH VACUUM TECHNOLOGY
Journal Article
·
· Nuclear Instr. and Methods
The production of ultra high vacuum ( approx equal 10/sup -9/ torr) as a means of eliminating unwanted impurities is considered with reference to thermonuclear devices. The methods of measuring and production of these low pressures are reviewed. Material characteristics are considered in relation to the special requirements of all metal systems which can be baked at 400 to 450 deg C. Methods of fabricating chambers with demountable Joints, windows, and shut- off valves that can withstand repeated bake-out are reviewed. (auth)
