Plasma accelerators driven by particle beams are a very promising future accelerator technology as they can sustain high accelerating fields over long distances with high energy efficiency. They rely on the excitation of a plasma wave in the wake of a drive beam. To generate the plasma, a neutral gas can be field-ionized by the head of the drive beam, in which case the distance of acceleration ...
The electronic structure, spectroscopic, and bonding properties of the ground, excited, and ionized states of iodine are studied within a four-component relativistic framework using the MOLFDIR program package. The experimentally determined properties of the Sg 1 ground state are well reproduced by our results calculated at the CCSD~T! level of theory. Relativistic effects and core– valence cor...
This paper examines five different models of electron thermal transport in laser produced spherical implosions. These are classical, classical with a flux limit f , delocalization, beam deposition model, and Fokker-Planck solutions. In small targets, the results are strongly dependent of f for flux limit models, with small f ’s generating very steep temperature gradients. Delocalization models ...
The fabrication and characterization of green, flexible, ultra-thin supercapacitors that are able to operate above 1.5 V is reported, using an all-printed process. devices produced by aqueous spray casting a natural-derived electrolyte ionogel composed 2-hydroxyethyl cellulose the ionic liquid choline lactate, while electrodes highly porous nanostructured carbon films deposited supersonic clust...
It is well-known that neutral beam injection is one of the fundamental fusion plasma heating methods. In general, a particle accelerator is used to create fast ion beams (the particle energies are on the order of 100 keV); the ion beam is then passed through a neutral gas region, where the ions neutralize via charge-exchange reactions with the neutral gas. The neutralized beam is then injected ...
Nanometer-scale compositional structure in InAsxP12x/InNyAsxP12x2y //InP heterostructures grown by gas-source molecular beam epitaxy and in InAs12xPx/InAs12ySby/InAs heterostructures grown by metalorganic chemical vapor deposition has been characterized using cross-sectional scanning tunneling microscopy. InAsxP12x alloy layers are found to contain As-rich and P-rich clusters with boundaries fo...
The frozen natural orbital (FNO) approach, which has been successfully used in ground-state coupled-cluster calculations, is extended to open-shell ionized electronic states within equation-of-motion coupled-cluster (EOM-IP-CC) formalism. FNOs enable truncation of the virtual orbital space significantly reducing the computational cost with a negligible decline in accuracy. Implementation of the...
