High current ionic flows via ultra-fast lasers for fusion applications
Abstract
In the present paper we introduce a new accelerator concept for ions. The accelerator is nano-structured and can consist of a range of materials. It is capable of generating large ionic currents at moderate ion energies. The nano-structures can be tailored towards the accelerator thus being capable of driving ion beams with very high efficiency. The accelerator is powered by laser arrays consisting of many repetitive and efficient lasers in the 100 \, J range with ultra-short intense laser pulses. Combining nano-structures and the proposed ultra-short pulse lasers can lead to new levels of spatio-temporal control and energy efficiency for fusion applications.
