Oral presentation
The basic principles of laser acceleration using a short pulse Petawatt laser are well established, and now is probably the right time to consider them as an interesting alternative to conventional accelerators, with some restrictions on one side and some advantages in other side. There are now a few Petawatt lasers at one shot per second operative around the world (Berkeley, Dresden and...

The Vulcan Petawatt Laser Facility is operational from different years, delivering high quality support for the laser plasma community. To keep the facility at world leading level, continuous development is necessary.
For that reason, to allow better understanding of the laser plasma interaction at petawatt level, a new laser beamline was proposed to allow betatron radiation probing of the...

The internal structure of porous materials determines the features of laser absorption and the characteristics of relaxation and transport processes in laser-produced plasma. Many experiments have been carried on in the last decades, producing a large dataset, which can be the base for improving theoretical models and numerical codes. The microscopic structure of these materials cannot be...

A 10-Hz repetition rate, Nd:YAG pulsed laser (λ=1064 nm, pulse energy of 700 mJ, pulse duration of 3 ns) was used to irradiate different double stream gas-puff targets (DSGPTs). The interaction gives rise to the formation of plasma and the emission of SXR/EUV radiation. The DSGPTs are produced by a 0.4 mm in diameter nozzle, which injects the working gas (N2, Ar or Xe) at different pressures,...

In this work we report the investigation of two different photocathodes (PCs) based on nanodiamonds (NDs) irradiated by a nanosecond excimer laser (KrF) operating at 248 nm (5eV). The ND layers of cathodes were deposited by means of pulsed spray technique. Specifically, the active ND layer of each PC consists of untreated or hydrogenated particles, 250 nm in size, sprayed on p-doped silicon...
