Space-charge transport limits of ion beams in periodic quadrupole focusing channels

It has been empirically observed in both experiments and particle-in-cell simulations that space-charge-dominated beams suffer strong growth in statistical phasespace area (degraded quality) and particle losses in alternating gradient quadrupole transport channels when the undepressed phase advance σ0 increases beyond about 85 per lattice period. Although this criterion has been used extensivel...

Subpicosecond carrier transport in GaAs surface-space-charge fields.

Above-band-gap pulsed optical excitation of electron-hole pairs within the surface-space-charge region of semiconductors alters the surface-space-charge field via free-carrier transport. We report on the direct observation of this ultrafast transient screening and the associated charge-carrier transport by applying reflective electro-optic sampling (REOS) with subpicosecond time resolution to (...

Phase space transport in noisy Hamiltonian systems.

This paper analyzes the effect of low amplitude friction and noise in accelerating phase space transport in time-independent Hamiltonian systems that exhibit global stochasticity. Numerical experiments reveal that even very weak non-Hamiltonian perturbations can dramatically increase the rate at which an ensemble of orbits penetrates obstructions like cantori or Arnold webs, thus accelerating t...

Charge transport: through space keeps up with the pace

Charge transport is a fundamental and crucial process in organic electronics. Modern understanding of the transport has shown that, on single molecule level, this process can be described by through bond (TB) and through space (TS) models. The quantitative deciphering of the TB process has been established in recent years by the aid of scanning tunneling microscope (STM) technique and by making...
