“…The development of shortpulse high-intensity lasers 2 made it possible to accelerate protons and heavier ions to multi-MeV energies in the interaction of these lasers with solid targets, [3][4][5][6] gas jets, 7 and clusters. 8 It was shown that these accelerated protons can induce nuclear transformations.…”

We have observed deuterons accelerated to energies of about 2 MeV in the interaction of relativistically intense 10 TW, 400 fs laser pulse with a thin layer of deuterated polystyrene deposited on Mylar film. These high-energy deuterons were directed to the boron sample, where they produced ∼105 atoms of positron active isotope C11 from the reaction B10(d,n)11C. The activation results suggest that deuterons were accelerated from the front surface of the target.

Charged particle acceleration using ultra-intense and ultra-short laser pulses has gathered a strong interest in the scientific community and it is now one of the most attractive topics in the relativistic laser-plasma interaction research. Indeed, it could represent the future of particle acceleration and open new scenarios in multidisciplinary fields, in particular, medical applications. One of the biggest challenges consists of using, in a future perspective, high intensity laser-target interaction to generate high-energy ions for therapeutic purposes, eventually replacing the old paradigm of acceleration, characterized OPEN ACCESSAppl. Sci. 2015, 5 428 by huge and complex machines. The peculiarities of laser-driven beams led to develop new strategies and advanced techniques for transport, diagnostics and dosimetry of the accelerated particles, due to the wide energy spread, the angular divergence and the extremely intense pulses. In this framework, the realization of the ELIMED (ELI-Beamlines MEDical applications) beamline, developed by INFN-LNS (Catania, Italy) and installed in 2017 as a part of the ELIMAIA beamline at the ELI-Beamlines (Extreme Light Infrastructure Beamlines) facility in Prague, has the aim to investigate the feasibility of using laser-driven ion beams in multidisciplinary applications. ELIMED will represent the first user's open transport beam line where a controlled laser-driven ion beam will be used for multidisciplinary and medical studies. In this paper, an overview of the beamline, with a detailed description of the main transport elements, will be presented. Moreover, a description of the detectors dedicated to diagnostics and dosimetry will be reported, with some preliminary results obtained both with accelerator-driven and laser-driven beams.

“…The position is usually chosen to optimize the density of proton tracks on the detectors, which begin to saturate if the incident proton density exceeds ~10 6 protons/cm 2 . The third slot makes possible the formation of images for D 3 He yields up to ~5x10 10 .…”

“…Such image data provide exacting tests for simulations. Burn images of deuterium-tritium-filled capsules have previously been envisioned 3 and made using 14.1-MeV neutrons, 4-7 3-MeV protons [8][9][10] or 3.5-MeV alpha particles 10 (see also other papers cited in Ref. 11).…”

A proton emission imaging system has been developed and used extensively to measure the nuclear burn regions in the cores of inertial confinement fusion implosions. Three imaging cameras, mounted to the 60-beam OMEGA laser facility [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)], use the penetrating 14.7-MeV protons produced from D 3 He fusion reactions to produce emission images of the nuclear burn spatial distribution. The imaging technique relies on penumbral imaging, with different reconstruction algorithms for extracting the burn distributions of symmetric and asymmetric implosions. The hardware and design considerations required for the imaging cameras are described. Experimental data, analysis, and error analysis are presented for a representative symmetric implosion of a fuel capsule with a 17-µm-thick plastic shell and 18-atm D 3 He gas fill. The radial burn profile was found to have characteristic radius R burn , which we define as the radius containing half the D 3 He reactions, of 32 ± 1.6 µm (burn radii measured for other capsule types range from 20 to 80 µm). Potential sources of error due to proton trajectory changes from interactions with electric fields and scattering in capsule and camera hardware are estimated with simple analytic and Monte Carlo calculations; they are predicted to be small compared with statistical errors. Experimental tests were performed to look for any inconsistencies between results from different cameras and different imaging geometries, or evidence of error due to ambient electric or magnetic fields, and none were found. a) seguin@mit.edu b) Also Visiting Senior Scientist, Laboratory for Laser Energetics, University of Rochester. c) Also
