Arie Irman (Helmholtz Zentrum Dresden Rossendorf)18/09/2023, 16:25WG5: ApplicationsOral contribution
Laser Plasma Accelerators (LPAs), harnessing gigavolt-per-centimeter accelerating fields, can generate high peak current, low emittance and GeV class electron beams paving the way for the realization of future compact free-electron lasers (FELs). Here, we report on the commissioning of the COXINEL beamline driven by the HZDR plasma accelerator and experimental demonstration of FEL lasing at...

Source (EuAPS), a betatron-based X-ray source for users, devoted to
several applications. In particular, we would like to focus on the
layout, the expected properties of the source, and its role as one of
the fundamental bricks of the EuPRAXIA project. -

Bright, high-energy X-ray beam sources with narrow bandwidths and tunable energies hold great potential for widespread use in a variety of novel applications as alternatives to large-scale and costly radiation sources. Inverse Compton scattering sources based on electron beams from laser-plasma accelerators represent a promising candidate for increasing availability. However, in practice these...

The collision of ultra-intense laser pulses with solids may initiate processes like current filamentation instability (CFI) and target normal sheath acceleration (TNSA). Studying the interplay of these processes is crucial, as they play an important role in novel particle accelerator concepts and are believed to be present in astrophysical events.
In the scope of this work, laser-solid...

The main results of the electron pulse and ultra-high-dose-rate (UHDR) parameter verification simulation studies are reported for the FLASH mode radiobiological treatment. There were reproduced the percentage depth dose (PDD) at energies: 5, 7, 15, 25, 50 and 100 MeV, to Poly-methyl-methacrylate (PMMA) and to water fantom vs the penetration depth. Additionally, the PDD transverse profile was...

Positron annihilation lifetime spectroscopy (PALS) is one of the methods for the non-invasive inspection of materials and identification of small-scale defects. PALS presents several unique advantages when compared to other inspection techniques: it works virtually with any type of material (crystalline and amorphous, organic and inorganic) and it can identify even sub-nanometer defects with...

Arnaud Courvoisier (Weizmann Institute of Science)20/09/2023, 16:25WG5: ApplicationsOral contribution
The notion of utilizing very high energy electrons (VHEE) in the 200MeV range for treating deep-seated cancerous tumors has recently gained traction in the particle accelerator community. As a result, numerous technical advances aimed at developing medically sound conventional and non-conventional electron accelerators have emerged. Since late 2022, the European Innovation Council has been...

Marco Borghesi (Queen's University Belfast)20/09/2023, 16:45WG5: ApplicationsOral contribution
The ultrashort nature of laser-driven proton bursts allows, with appropriate arrangements, to perform single pulse irradiation of cellular samples at dose rates reaching 1010 Gy/s. Motivated by the FLASH radiotherapy context, there is significant interest in assessing any divergence in biological response at these ultra-high dose rates (UHDR) from the behaviour observed in irradiations under...

Laser-driven (LD) proton sources are of interest for various applications due to their ability to produce short proton bunches with high charge and low emittance. These sources can be used in biological studies investigating improvements to radiation cancer therapy. Recently, the differential sparing effect on normal tissues versus tumors using the delivery of high radiation doses >10 Gy at...

Wenchao Yan (Shanghai Jiao Tong University)20/09/2023, 17:25WG5: ApplicationsOral contribution
Electron–photon scattering is one of the most fundamental mechanisms in electrodynamics, underlying laboratory and astrophysical sources of high-energy X-rays. After a century of studies, it is only recently that sufficiently high electromagnetic field strengths have been available to experimentally study the nonlinear regime of the scattering in the laboratory. This can act as a new...

By colliding 10 GeV, high-quality electron beams with 10 TW NIR laser pulses it is aspired to probe the QED critical (Schwinger) intensity of 10$^{29}$ W$\text{cm}^{-2}$ in the electron rest frame.
In this regime, characterized by $\chi = E^*/E_{\text{cr}} \gtrsim 1$, quantum corrections to... -

The passage of an electron bunch through a conducting foil has a focusing effect from the Near-Field Coherent Transition Radiation (NF-CTR) generated on the surfaces. Passing through multiple foils may allow to focus bunches down to solid densities and generate collimated gamma-rays with micrometer source sizes and conversion efficiencies exceeding 10%. The possibility offered by this scheme...
