ELI-NP

Extreme Light Infrastructure - Nuclear Physics

 

The high power laser system (HPLS) represents one of the two unique tools at the core of ELI-NP facility. It is based on the ultrashort laser pulses generation and Chirped Pulse Amplification technique introduced by D Strickland and G Mourou in 1985.  This class of ultra-short and ultra-intense laser systems can provide pulses with three outstanding features associated to space, time and forces, balanced in a trade-off, as follows.

The temporal feature is connected to the pulse duration on the pulse and the associated temporal contrast. The spatial feature is related to the spot size in which the field is concentrated in the focal region. The forces correspond to the electromagnetic field associated to the laser pulse itself.

 ELI-NP will host a highly versatile gamma beam system (GBS) able to provide gamma-ray beams with continuously tunable energy in the range from 200 keV to 19.5 MeV.  Production of quasi-monochromatic gamma beams is based on the Inverse Compton Scattering (ICS) process of laser light pulses off relativistic electron bunches. To generate high-brilliance beams, the solution adopted in the case of ELI-NP was to minimize the interaction volume and maximize the number of photons and electrons within the interaction volume by using low-emittance electron beams and high-brilliance laser pulses. The resulting GBS is based on a high-quality electron-photon collider with luminosity at the level of about 2 × 1035 cm-2 s-1, almost an order of magnitude better than the one achieved at LHC in CERN.

 The first category is laser-driven experiments related to nuclear physics, strong-field quantum electrodynamics and associated vacuum effects. The second is based on a Compton backscattering high-brilliance and intense low-energy gamma beam (<20 MeV), a marriage of laser and accelerator technology which will allow us to investigate nuclear structure and reactions as well as nuclear astrophysics with unprecedented resolution and accuracy. In addition to fundamental themes, a large number of applications with significant societal impact will be developed. The ELI-NP research centre is located in Măgurele, Bucharest, Romania. The project is implemented by ‘Horia Hulubei’ National Institute for Physics and Nuclear Engineering (IFIN-HH). The project started in January 2013 and the new facility will be fully operational in 2020.
