Annular shaped laser-accelerated proton beams
Since their discovery in 1999 [1] the topic of laseraccelerated ions has attracted high attention both in the field of plasma-physics and in the accelerator community. In a typical laser-accelerated ion scheme a thin metal foil is irradiated by an ultra-intense chirped pulse amplified laser beam which leads to the generation of relativistic electrons. These electrons are accelerated through the...
متن کاملLaser-Accelerated Proton Beams as Diagnostics for Cultural Heritage
This paper introduces the first use of laser-generated proton beams as diagnostic for materials of interest in the domain of Cultural Heritage. Using laser-accelerated protons, as generated by interaction of a high-power short-pulse laser with a solid target, we can produce proton-induced X-ray emission spectroscopies (PIXE). By correctly tuning the proton flux on the sample, we are able to per...
متن کاملDynamic control of laser-produced proton beams.
The emission characteristics of intense laser driven protons are controlled using ultrastrong (of the order of 10(9) V/m) electrostatic fields varying on a few ps time scale. The field structures are achieved by exploiting the high potential of the target (reaching multi-MV during the laser interaction). Suitably shaped targets result in a reduction in the proton beam divergence, and hence an i...
متن کاملMonoenergetic Proton Beams from Laser Driven Shocks
Laser driven ion acceleration (LDIA) has the potential to deliver compact and affordable accelerators for applications in many fields of science and medicine. Specifically, radiotherapy of cancerous tumors requires ion energies in the range of 200-300 MeV/a.m.u. and with energy spreads on the order of 5%, parameters thus far beyond the LDIA experimental results using the most powerful lasers in...
متن کاملInstrumentation for diagnostics and control of laser-accelerated proton (ion) beams.
Suitable instrumentation for laser-accelerated proton (ion) beams is critical for development of integrated, laser-driven ion accelerator systems. Instrumentation aimed at beam diagnostics and control must be applied to the driving laser pulse, the laser-plasma that forms at the target and the emergent proton (ion) bunch in a correlated way to develop these novel accelerators. This report is a ...
