Versatile tape-drive target for high-repetition-rate laser-driven proton acceleration

Popis výsledku v původním jazyce

We present the development and characterization of a high-stability, multi-material, multi-thickness tape-drive target for laser-driven acceleration at repetition rates of up to 100 Hz. The tape surface position was measured to be stable on the sub-micrometre scale, compatible with the high-numerical aperture focusing geometries required to achieve relativistic intensity interactions with the pulse energy available in current multi-Hz and near-future higher repetition-rate lasers (>kHz). Long-term drift was characterized at 100 Hz demonstrating suitability for operation over extended periods. The target was continuously operated at up to 5 Hz in a recent experiment for 70,000 shots without intervention by the experimental team, with the exception of tape replacement, producing the largest data-set of relativistically intense laser– solid foil measurements to date. This tape drive provides robust targetry for the generation and study of high-repetition rate ion beams using next-generation high-power laser systems, also enabling wider applications of laser-driven proton sources.
