Particle accelerators at the energy frontier are getting ever larger. Plasma-based particle accelerators operate at gradients in the 1-100GeV/m and could become a new, more compact and therefore cheaper accelerator technology. In the plasma wakefield accelerator (PWFA) the accelerating gradient is driven by a short particle bunch. PWFA experiments have already demonstrated energy gain by...

We review the basic features of particle acceleration theory around collisionless shocks in astrophisical environments.
Special attention will be devoted to observational and theoretical facts about acceleration of Galactic cosmic rays in supernova remnants, discussing the arguments in favor and against a connection between cosmic rays and supernova remnants, the so-called supernova remnant...

The development of Extreme Field Science will make it possible to
explore novel phenomena, to study processes of basic importance
for physics, and to model in the laboratory processes of key
importance for relativistic astrophysics. Experiments in this field
will allow allow us to model in a terrestrial laboratory the state
of matter that is thought to occur in cosmic Gamma Ray...

Ion acceleration from solid targets irradiated by high-intensity pulses is a burgeoning area of research, attracting a phenomenal amount of experimental and theoretical attention worldwide. Key to this interest are the ultra-compact spatial scale of the accelerator and the properties of the laser-driven ion beams, under several aspects markedly different from those of "conventional"...

The magnetic field is fundamental to solar activity and shapes the interplanetary environment, as clearly shown by the full three dimensional monitoring of the heliosphere provided by the measurements of the Helios, Ulysses, SOHO, ACE, Wind, STEREO and Voyager spacecraft. Magnetic fields are also the source for coronal heating and the very existence of the solar wind; produced by the sun’s...

Lightning and thunderstorm systems in general have been recently recognized as powerful particle accelerators, capable of producing electrons, positrons, gamma-rays and neutrons with energies as high as several tens of MeV. In fact, these natural systems turn out to be the highest energy and most efficient natural particle accelerators on Earth. Terrestrial Gamma-ray Flashes (TGFs) are few...
