“…Commonly, an ES is implemented as follows: a magnetic dipole chicane with one entrance slit and one selecting slit (see Fig. 1) (Chen et al, 2014;Scuderi et al, 2014;Scisciò et al, 2018). The entrance slit (a 1 ) reduces the initial divergence of the beam that enters the dipoles.…”

“…These laser-generated proton beams have unique characteristics, such as high charge (10 13 particles/shot), high laminarity at the source, short bunch duration (ps at the source), and a high peak current (kA at the source). These characteristics make them desirable candidates for several applications that require one or more of the mentioned properties, such as biomedicine (tumor treatment, PET, radiography) (Bulanov et al, 2002;Malka et al, 2004), warm dense matter (Patel et al, 2003;Antici et al, 2006;Bulanov et al, 2010;Mancic et al, 2010), hybrid acceleration schemes (Antici et al, 2008;Scisciò et al, 2018) and material science (Dromey et al, 2016;Barberio et al, 2017aBarberio et al, , 2018aBarberio et al, , 2018b. Recently, the use of laseraccelerated proton beams as diagnostic for chemical analysis of cultural heritage (CH) artifacts has been investigated (Barberio et al, 2017b; Barberio and Antici, 2019;Passoni et al, 2019).…”

“…In particular, between 2008 and 2011, several groups used a set of PQMs (Ter-Avetisyan et al, 2008;Nishiuchi et al, 2009), that, respectively, focused proton beams in the range of (3.7 ± 0.3) MeV, collected a final bunch of ∼10 8 particles and (2.4 ± 0.1) MeV with ∼10 6 particles. For reducing the energy spread of the protons, passive magnetic chicanes (Chen et al, 2014;Scuderi et al, 2014;Scisciò et al, 2018) have been employed as energy selectors (ES).…”

“…In this work, we aim at optimizing the performance of a laserdriven hybrid beamline and compare it to typical parameters of conventional facilities dedicated to PIXE spectroscopy. The proposed beamline design includes an ES, with similar features as reported in Scisciò et al (2018), followed by magnetic focusing devices [i.e., Permanent Magnet Quadrupoles (PQM)] in order to vary the final transverse dimensions of the energy-selected beam on the CH sample. The used ES provides the possibility of tuning the beam energy in the range that is typical for the PIXE analysis, that is, 1-5 MeV, reducing the initial energy spread to a final value of ≤10%.…”

Multi-MeV proton beams can be generated by irradiating thin solid foils with ultra-intense (>1018 W/cm2) short laser pulses. Several of their characteristics, such as high bunch charge and short pulse duration, make them a complementary alternative to conventional radio frequency-based accelerators. A potential material science application is the chemical analysis of cultural heritage (CH) artifacts. The complete chemistry of the bulk material (ceramics, metals) can be retrieved through sophisticated nuclear techniques such as particle-induced X-ray emission (PIXE). Recently, the use of laser-generated proton beams was introduced as diagnostics in material science (laser-PIXE or laser-driven PIXE): Coupling laser-generated proton sources to conventional beam steering devices successfully enhances the capture and transport of the laser-accelerated beam. This leads to a reduction of the high divergence and broad energy spread at the source. The design of our hybrid beamline is composed of an energy selector, followed by permanent quadrupole magnets aiming for better control and manipulation of the final proton beam parameters. This allows tailoring both, mean proton energy and spot sizes, yet keeping the system compact. We performed a theoretical study optimizing a beamline for laser-PIXE applications. Our design enables monochromatizing the beam and shaping its final spot size. We obtain spot sizes ranging between a fraction of mm up to cm scale at a fraction of nC proton charge per shot. These results pave the way for a versatile and tunable laser-PIXE at a multi-Hz repetition rate using modern commercially available laser systems.

Carbon‐Based Nanostructured Film Materials for High‐Intense Laser‐Matter Interaction Experiments

et al. 2018

View full text Add to dashboard Cite

In this paper, a new synthesis of carbon‐based nanostructured films for application as plasma facing materials during high‐intense laser‐matter interaction experiments is presented. The materials are produced using a Polyethylene glycol (PEG) matrix, nanostructured with multiwalled carbon nanotubes, or multi‐layer graphene flakes producing a 250 μm thick film. The films are deposited onto typical materials used in harsh environments such as plasma facing materials. These PEG reinforced materials are irradiated by laser‐accelerated particles and by an in‐air plasma, both are techniques that have shown to heavily stress and damage materials used in laser‐matter interaction experiments. The authors observe that the chemical structure of the PEG reinforced materials, when irradiated by both techniques, stays unchanged. However, one can see that the PEG layer adds considerable longevity to the underlying materials, making it more robust against erosion and ablation occurring during its operation.
