Journal ArticleDOI
Thermal desorption of gases
TL;DR: In this paper, the activation energy, rate constant and order of reaction from flash-filament desorption experiments were examined, and two heating schedules were considered: a linear variation of sample temperature with time (T = T 0+st), and a reciprocal temperature variation (1 T = 1 T 0 −αt).
Journal ArticleDOI
The effects of adsorbed oxygen on measurements with ionization gauges
TL;DR: In this article, the effects of electron bombardment on the measurement of pressure in the presence of adsorbed oxygen on molybdenum have been discussed and the modulator potential has little effect on ions formed at the grid with initial energy.
Journal ArticleDOI
Instabilities in crossed-field discharges at low pressures
TL;DR: In this paper, the authors review the existing studies of crossed-field discharges at low pressures and the more recent work on magnetically-confined pure electron plasmas, to clarify the causes of instabilities and nonlinearities and suggest methods for reducing these anomalous effects.
Journal ArticleDOI
The first 50 years of electron stimulated desorption (1918-1968)
TL;DR: The Menzel-Gomer-Redhead (MGR) model of ESD was independently developed by Menzel and Gomer in Chicago and Redhead in Ottawa in the early 1960s as discussed by the authors.
Journal ArticleDOI
The ultimate vacuum
TL;DR: In this paper, a brief historical review is presented of the key advances that caused significant decreases in the ultimate vacuum during the period 1660-1900 and the major improvements in ultimate vacuum in the period from 1950 to the present are reviewed and the limitations to the current time examined.
