physics with high power lasers at ELI-NP"
Extreme Light Infrastructure ‐ Nuclear Physics, Magurele, Romania
Extreme Light Infrastructure – Nuclear Physics (ELI-NP) in Romania, will
host two world-leading photon facilities: (i) a system of two 10 PW
lasers delivering 200 J pulses with 20 fs duration and synchronizable on
the fs scale and (ii) a Gamma Beam System (GBS) providing gamma rays
with continuously tunable energy in the range from 200 keV to 19.5 MeV,
based on Inverse Compton Scattering of laser light pulses on
relativistic electron bunches. Eight interaction chambers in separate
experimental areas will enable a wide range of nuclear physics
experiments, including laser-laser, laser-gamma beam, and gamma beam
only based setups.
The extreme light intensity achievable with the 10 PW ELI-NP lasers will
enable producing extreme electric fields of over 1015 V/cm, and extreme
light pressures of over 1013 bar. The extreme laser electric field
will serve to study strong-field QED phenomena, such as non-linear
inverse Compton scattering, radiation reaction, and Breit-Wheeler pair
production. The extreme light pressure will enable acceleration of near
solid density ion bunches to energies of the order of 10 MeV/nucleon,
opening the possibility of producing exotic nuclear reactions, which
either require chains of interactions, or have very low cross sections.
An example is the production of neutron-rich nuclei around the N=126
waiting point through fission-fusion reactions, for studies of heavy
The possibility to combine in one experiment the high power laser beams
with the gamma beam or with the relativistic electron beam from the GBS
linac is another unique feature of the ELI-NP facility. Example of
laser-gamma beam experiments envisaged are laser driven production of
isomers followed by their photoexcitation with the gamma beam, studies
of quantum radiation reaction, and pair creation in vacuum.
Lastly, the narrow-bandwidthγ,n) and (γ,α) reactions and photofission.
The NRF experiments will target nuclei which were are beyond reach
nowadays, such as in the actinide region. The PDR and GDR studies will
address the problem of nuclear polarizability. The measurements of
photonuclear reaction cross sections will be related to nuclear
astrophysics reaction networks and to precise measurements of key
reactions of nuclear astrophysics interest. The photofission studies
will be related to the understanding of the landscape of the potential
barriers in the light actinide nuclei.
The plans for Day-1 experiments at ELI-NP will also be presented.
first Nuclear Physics Joint Seminar for 2016 will be held next
Monday, Nov 21st. at the Weizmann Institute. The seminar will take
place in the large seminar room of the Physics building.
