Most of the building services in E4 are provided through hubs with unified connection panels. The building services provide HVAC and lights as well as several distributed utilities for specific usage, such as primary vacuum (backing and rough), de-mineralized cooling water, compressed, clean, dry air, gaseous nitrogen at room temperature, communication networks, drainage, and exhalation exhaust.
The E4 experimental area allows users to test various samples with laser accelerated ion sources because of its ion beam transport and dosimetry section, as well as to investigate innovative schemes for laser-driven ion acceleration that can be accommodated in the flexible interaction chamber.
ELIMAIA will be one of the key secondary source target areas of the ELI Beamlines facility. The proposed technological and scientific solutions for the implementation of the ELIMAIA beamline is the result of a complex investigation carried out in the last several years with the main goal of fulfilling the specific requirements that have been coming from the international user community.
According to the state of the art in laser-driven ion acceleration, maximum proton energies of several tens of MeV have been experimentally achieved with a relatively high yield (1010-1012 protons/pulse). However, laser-accelerated ion beams are still not mature for several applications in which additional features, such as low divergence, monoenergeticity, spatial profile uniformity, or shot-to-shot stability, are essential. Nevertheless, new laser technologies that will soon be available, e.g. ELI Beamlines, will allow the scientific community to investigate new regimes that are very promising in terms of future use of laser-driven ion beams for various applications.
