Laser wakefield acceleration is able to provide electron beams of GeV energy and continuously evolves toward higher energies. These beams have broad energy spectrum; hence, their measurements require diagnostics with wide energy acceptance. Here, we

Optical vortices, generated by a spiral phase plate, were propagated over long distances and focused in the PW experimental area. A deformable mirror was used to correct the low-order distortions, obtaining a doughnut focus.

Recently developed short‐pulsed laser sources garner high dose‐rate beams such as energetic ions and electrons, x rays, and gamma rays. The biological effects of laser‐generated ion beams observed in recent studies are different from those trig

One of the specific properties of laser-driven radiation is a broadband energy spectrum, which is also a feature of the space radiation fields. This property can be used in materials science studies or radiobiology experiments to simulate the energy
