Characterization and performance of the Apollon short-focal-area facility following its commissioning at 1 PW level

Publikováno v: Matter and Radiation at Extremes, Vol 6, Iss 6, Pp 064402-064402-14 (2021)

We present the results of the first commissioning phase of the short-focal-length area of the Apollon laser facility (located in Saclay, France), which was performed with the first available laser beam (F2), scaled to a nominal power of 1 PW. Under t

Re-examining the transition into the N=20 island of inversion: Structure of 30Mg

Publikováno v: Physics Letters B, Vol 779, Iss , Pp 124-129 (2018)

Intermediate energy single-neutron removal from 31Mg has been employed to investigate the transition into the N=20 island of inversion. Levels up to 5 MeV excitation energy in 30Mg were populated and spin-parity assignments were inferred from the cor

Extreme brightness laser-based neutron pulses as a pathway for investigating nucleosynthesis in the laboratory

Autor: S. N. Chen, F. Negoita, K. Spohr, E. d’Humières, I. Pomerantz, J. Fuchs

Publikováno v: Matter and Radiation at Extremes, Vol 4, Iss 5, Pp 054402-054402-10 (2019)

With the much-anticipated multi-petawatt (PW) laser facilities that are coming online, neutron sources with extreme fluxes could soon be in reach. Such sources would rely on spallation by protons accelerated by the high-intensity lasers. These high

An above-barrier narrow resonance in 15F

Publikováno v: Physics Letters B, Vol 758, Iss C, Pp 26-31 (2016)

Intense and purified radioactive beam of post-accelerated 14O was used to study the low-lying states in the unbound 15F nucleus. Exploiting resonant elastic scattering in inverse kinematics with a thick target, the second excited state, a resonance a

Experimental demonstration of ultrahigh sensitivity Talbot-Lau interferometer for low dose mammography

Autor: N Safca, D Stutman, E Anghel, F Negoita, C A Ur

Publikováno v: Physics in medicine and biology. 67(23)

Objective. Even though the techniques used for breast cancer identification have advanced over the years, current mammography based on x-rays absorption, the ‘gold standard’ screening test at present, still has some shortcomings as concerns sensi

Ultrahigh sensitivity grating interferometry for laser-based X-ray phase contrast imaging

Autor: N. Safca, D. Stutman, E. Anghel, F. Negoita, C.A. Ur

Publikováno v: Optica High-brightness Sources and Light-driven Interactions Congress 2022.

Ultrahigh sensitivity X-ray interferometry using micron-period gratings in long Talbot-Lau geometries is developed at ELI-NP, towards laser-based X-ray phase contrast imaging for medical applications. Results on mammography phantoms confirm the capab
