1984“…It is found that the desorption yields h (molecules/electron) of the characteristic gases in an UHV system (hydrogen, methane, water, carbon monoxide, carbon dioxide) for a fully activated NEG as well as for a NEG fully saturated with 13C18O are lower than for OFHC copper baked at 120oC. A small fraction only of the gas which is required to saturate the getter surface can be re-desorbed and thus appears to be accessible to ESD.…”

1986“…The volume will be composed of eight medium-pressure (2 MPa) gas storage tanks made of carbon steel, which constrains the temperature of the wall to be higher than -50 oC (223 K). Possible spot cooling intensity and thermo-mechanical stresses in the tank wall following helium injection have been analysed previously and the aim of the present study is experimental verification of basic assumptions concerning cryogenic jet parameters and heat transfer between jet crown and tank wall. …”
