Simulation of Self-pinched Chamber Transport of Ions for Heavy Ion Fusion*
نویسندگان
چکیده
In this paper, we explore the self-pinched transport of heavy ions in an inertial confinement fusion reactor chamber environment. The bulk of this work is carried out using a hybrid particle-in-cell code. The initial results show that a neutral flibe pressure of roughly 550 mtorr is sufficient to produce a net current capable of confining the ions at small radius (<5 mm). The source and sensitivity to chamber conditions of the self-pinch force are discussed.

Simulation study of the transport properties of ions through ion channels serving as primary components of a nanobiosensor
Ion channels are naturally occurring pores through the proteins that regulate the passage of ions and thus maintain the concentration of ions inside and outside the cell. The ion channels control many physiological functions and they can show selectivity for a specific ion. Ion channels are mostly observed in nerve cells and muscle cells. The influx of ions into cells can be regulated by a gate...

متن کاملPotential Roles for Heavy Negative Ions as Driver Beams
We have assessed the feasibility of producing heavy negative ion beams as drivers for an inertial confinement fusion reactor. Negative ion beams offer the potentially important advantages relative to positive ions that they will not draw electrons from surfaces and the target chamber plasma during acceleration, compression and focusing, and they will not have a low energy tail. Intense negative...
متن کاملEvaluation of Multielectron Ionization Cross-Sections in Energetic Ion-Atom Collisions
The use of heavy ions beams with mass of order 100 atomic mass units and energy of order 10 MeV per nucleon has been proposed as a driver for heavy ion fusion. Multi-electron-loss collisions of the beam ions with the background gas atoms result in an increase in the ion charge, which is an unwanted effect for beam propagation through the accelerator and transport regions, and the target chamber...
متن کاملRemoval of Heavy Metal Particles by LTJ, ANA, SVR, BEC and MER zeolites particles: A Molecular Dynamics Simulation Study
In present study, molecular dynamics simulation of Cadmium (II), Lead (II) and Copper (II) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. The results showed that, most of the particles had the highest affinity of ion exchanging with Lead (II) and the lowest affinity with Copper (II). The calculated mean ion-exchange ratios showed t...
