Electron drift velocity measurements in liquid krypton}methane mixtures

چکیده
Electron drift velocities have been measured in liquid krypton, pure and mixed with methane at di!erent concentrations (1}10% in volume) versus electric "eld strength, and a possible e!ect of methane on electron lifetime has been investigated. While no e!ect on lifetime could be detected, since lifetimes were in all cases longer than what measurable, a very large increase in drift velocity (up to a factor 6) has been measured.

Self Diffusion and Binary Maxwell-Stefan Diffusion in Simple Fluids with the Green-Kubo Method
Self diffusion coefficients and binary Maxwell-Stefan diffusion coefficients were determined by equilibrium molecular dynamics simulations with the Green-Kubo method. The study covers five pure fluids: neon, argon, krypton, xenon, and methane and three binary mixtures: argon+krypton, argon+xenon, and krypton+xenon. The fluids are modeled by spherical Lennard-Jones pair-potentials, with paramete...
متن کاملA molecular simulation study of shear and bulk viscosity and thermal conductivity of simple real fluids
Shear and bulk viscosity and thermal conductivity for argon, krypton, xenon, and methane and the binary mixtures argon+krypton and argon+methane were determined by equilibrium molecular dynamics with the Green-Kubo method. The fluids were modeled by spherical Lennard-Jones pair-potentials with parameters adjusted to experimental vapor liquid-equilibria data alone. Good agreement between the pre...
متن کاملScanning drift tube measurements of electron transport parameters in different gases: argon, synthetic air, methane and deuterium
Measurements of transport coefficients of electrons in a scanning drift tube apparatus are reported for different gases: argon, synthetic air, methane and deuterium. The experimental system allows the spatio-temporal development of the electron swarms (‘swarm maps’) to be recorded and this information, when compared with the profiles predicted by theory, makes it possible to determine the ‘time...

Measurements of electron transport, effective ionization, and attachment coefficients are reported for C2F4' In addition, measurements of the electron drift velocity and the effective ionization coefficient as a function of the density-reduced electric field E/N are reported for mixtures of C2F4 with Ar. The measured effective ionization coefficients in C2F4/Armixtures indicates a contribution ...
متن کاملElectron attachment , effective ionization coefficient , and electron drift velocity for CF 4 gas mixtures
For tracking in a SSC experiment with wire chambers, CF 4 gas mixtures are very advantageous from the point of view of aging, drift velocity, and spatial resolution. However, they are also known to suffer from considerable electron attachment. This attachment can cause serious inefficiencies in the collection of electrons liberated near the anode wire, and causes broadening of the pulse-height ...
