We report the results of simulations that explain many properties of ultracold neutral plasmas. We find that three-body recombination is important at very low temperatures since it is a heating mechanism for the electron gas and it preferentially removes the slow ions from the plasma. We also find that collisions between cold electrons and Rydberg atoms are an important source of electron heati...

VME based Ion Cyclotron Resonance Heating (ICRH) Data Acquisition Control system (DAC) is commissioned for remote operation of heating experiment on SST-1 tokamak. Linux client software of DAC using has been connected with Ethernet network. DAC client acts as Experimental Physics and Industrial Control System (EPICS) (Input/ Output Controller) IOC server which is used for other Ethernet connect...

A microscopic theory for the interaction between semiconductor quantum well structures and laser eld based on the semiconductor Bloch equations is applied to vertical-cavity surface-emitting lasers (VCSELs) with the inclusion of plasma heating. The semiconductor Bloch equations are reduced to those for the rst and second moments of the carrier density distributions in the carrier wave vector. P...

Numerical simulations and experimental results have shown that the formation of current sheets in space plasmas can be associated with enhanced vorticity. Also, generation such structures is strong plasma heating. Here, we compare four-point measurements terrestrial magnetosheath turbulence from Magnetospheric Multiscale mission flow vorticity magnetic field curlometer versus their correspondin...

On the Madison Symmetric Torus magnetic fusion plasma experiment, frozen pellet injection is an established method of depositing deuterium fuel into the core of the plasma. To freeze deuterium gas into pellets, the injector is cooled to 10 K with a cryogenic helium refrigerator. To exhaust residual frozen deuterium following injection of each pellet, the injector is warmed by resistive heating ...

A one-dimensional model of a small plasma ion source 10 cm long is studied. A hybrid simulation where ions are treated as particles and electrons as a fluid obeying the Boltzmann relation is used to investigate ion heating in the plasma presheath. At low pressure below a few mTorr , the ion velocity distribution is Maxwellian in the bulk and becomes a drifting Maxwellian distribution while tran...
