An Improved High Vacuum Mercury Vapor Pump

Pressure Dependence of Liquid Vapor Pressure: An Improved Gibbs Prediction

A new model for the vapor phase of a pressurized liquid called "the cluster model: which is originally introduced in this work, along with an accurate equation of state for the liquid phase called the LIR, is used to derive an accurate equation for the vapor pressure of liquid as a function of external pressure. The chemical Potential of both phase have been found to be in good agreement wi...

Generation of high-brightness coherent radiation in the vacuum ultraviolet by four-wave parametric oscillation in mercury vapor.

Coherent radiation at several wavelengths in the vacuum ultraviolet (VUV) has been generated by four-wave parametric oscillation in mercury vapor. When a powerful ultraviolet pump laser of frequency omega(p) is tuned to a two-photon resonance, VUV signal photons at frequency omega(s), as well as idler photons at frequency omega(i), are generated such that omega(s) + omega(i) = 2omega(p). A freq...

The Hazards of Mercury Vapor

When I decide to tell a wider audience everything about personal troubles, which in themselves do not concern others and therefore should not be worth publishing, it is because of an intense wish to spare others, who have anything to do with metallic mercury, the very bad experiences which have destroyed a major part of my life and to very emphatically warn against the volatile metal. I can fre...

Emergency power source for an ion vacuum pump.

This note describes a simple high-voltage dc generator which serves as an emergency power source for an ion vacuum pump during power interruptions, or failure of the main supply.
