Ion gauge theory
WebThe exploration of the phase diagram of quantum chromodynamics (QCD) is of great importance to describe e.g. the properties of neutron stars or heavy-ion collisions. Due to the sign problem of lattice QCD at finite chemical potential we need effective theories to study QCD at finite density. Here, we will use a three-dimensional Polyakov-loop theory … WebHot Filament Ionization Gauge Tubes HISTORY Glass ion gauge tubes evolved from triode radio tubes. In early configurations, a filament was in the center with a grid surrounding the filament and a collector surrounding the grid. Electrons were emitted from the hot filament and attracted by a positive electrical potential toward the grid.

WebWe study the thermalization process in highly occupied non-Abelian plasmas at weak coupling. The non-equilibrium dynamics of such systems is classical in nature and can be simulated with real-time lattice gauge theory … WebThe Bayard-Alpert ionization gauge (BAG) was first described in 19501. Modern versions of the gauge have preserved most of the basic elements of its original …
Web22. In normal usage, a gauge is a particular choice, or specification, of vector and scalar potentials A and ϕ which will generate a given set of physical force fields E and B. More specifically, a physical situation is specified by the electric and magnetic fields, E and B. A set of potentials A and ϕ generates the force fields if it obeys ...

WebOperating principle of sputter-ion pumps. The ions impinge upon the cathode of the cold cathode discharge electrode system and sputter the cathode material (titanium). The titanium deposited at other locations acts as a getter film and adsorbs reactive gas particles (e.g., nitrogen, oxygen, hydrogen). The energy of the ionized gas particles is ... WebThe Pirani gauge is a robust thermal conductivity gauge used for the measurement of the pressures in vacuum systems. It was invented in 1906 by Marcello Pirani. Marcello …
WebIt is commonly believed that the filament in a Bayard-Alpert gauge (BAG) presents a reliability problem (especially when compared to Cold Cathode Gauges) and it is …
