Abstract Radiotherapy with very high energy electrons has been investigated for a couple of decades as an effective approach to improve dose distribution compared conventional photon-based radiotherapy, the recent intriguing potential dose-rate irradiation. Its practical application treatment hindered by lack hospital-scale accelerators. High-gradient laser-plasma accelerators (LPA) have proposed possible platform, but no experiments so far explored feasibility clinical use this concept. We...

Abstract The interaction of ultraintense laser pulses with solids is largely affected by the plasma gradient at vacuum–solid interface, which modifies absorption and ultimately, controls energy distribution function heated electrons.

Particle-In-Cell 2D simulations reveal that packed favour better laser-plasma coupling produce efficient generation fast electrons moving through...
Particle-induced x-ray emission (PIXE) is a well-established ion-beam analysis technique, enabling quantitative measurement of the elemental composition sample surface under an ambient atmosphere with external beam, which significantly simplifies measurements, and strictly necessary for those samples that cannot sustain vacuum environment. Few-MeV electrostatic proton accelerators are used today in PIXE systems. We present here beam methodology based on compact laser-driven accelerator. A...
Accurate dynamic three-dimensional (4D) imaging of the heart small rodents is required for preclinical study cardiac biomechanics and their modification under pathological conditions, but technological challenges are met in laboratory practice due to very size high pulse rate mice rats as compared humans.
