High Bandwidth Pickup Design for Bunch Arrival-time Monitors for Free-Electron Laser
High Bandwidth Pickup Design Bunch Arrival-time Monitors Free-Electron Laser
2012/2/24
In this paper, we present the design and realization of high bandwidth pickup electrodes with a cutoff frequency above 40 GHz. The proposed cone-shaped pickups are part of a bunch arrival-time monitor...
Convergence of many-body wavefunction expansions using a plane wave basis: from the homogeneous electron gas to the solid state
Convergence many-body wavefunction expansions plane wave basis homogeneous electron gas solid state
2012/2/22
Using the finite simulation-cell homogeneous electron gas (HEG) as a model, we investigate the convergence of the correlation energy to the complete basis set (CBS) limit in methods utilising plane-wa...
Computation of electron quantum transport in graphene nanoribbons using GPU
