  1. Extreme Light Infrastructure in Romania: progress Daniel URSESCU Technical contact point for ELI in Romania INFLPR, Magurele, Romania

  2. Design Criteria • dual front-end (only one running at a time, 10-15 fs @100 mJ) • 3 arms (energy up to 300 J each, before compression) • separate room for pump lasers (first floor) • high rep. rate experimental area (underground 1) and high energy experimental area (underground 2) • extendable experimental area • parallel experiments operation

  3. Preliminary: ELI Nuclear Building First floor: pump lasers Ground floor: 2 x front-end laser and 3 x amplifiers Underground 1 and 2: experimental area

  4. 2xFRONT END DPSSL-pumped OPCPA AMPLIFIERS Ti:Sapphire pumped by ns Nd:YAG & Nd:Glass lasers DIAGNOSTICS A3 +A4+ A5 POWER AMPLIFIERS >300 J A1 + A2 BOOSTERS > 4 J, 10Hz FE1: 10-20 mJ BW > 120 nm TCP = 50 ps 0.1-1 kHz C > 10^12 BEAM TRANSPORT IN VACUUM COMPRESSOR >200 J COMPRESSOR 200 J A3 +A4+ A5 POWER AMPLIFIERS >300 J A1 + A2 BOOSTERS > 4 J, 10Hz BEAM TRANSPORT IN VACUUM COMPRESSOR 200 J COMPRESSOR >200 J TARGETS FE2: > 100 mJ BW > 80 nm TCP= 1-2 ns 10-100 Hz C > 10^12 A3 +A4+ A5 POWER AMPLIFIERS >300 J A1 + A2 BOOSTERS > 4 J, 10Hz BEAM TRANSPORT IN VACUUM COMPRESSOR >200 J COMPRESSOR 200 J Φ = 1-20 μm IΣ = 3 x 1023 -24W/cm2 TEST COMPRESSOR TARGETS DIAGNOSTICS BW – Spectral bandwidth, C – intensity contrast, TCP- chirped pulse duration, TC – re-compressed pulse duration, Φ – focused laser beam diameter, IΣ – intensity on target Laser Architecture

  5. Ground floor building description Adaptive optics, beam transport and diagnostics 3 x Amplification chains 2 x Front ends Technical rooms

  6. First floor building description Technical infrastructure area Pump lasers area Technical rooms

  7. Interaction Areas High energy compressors Beam delivery Front end target areas High energy target areas 3 PW high rep. rate target areas

  8. Technical issues: laser system • final pulse duration (>15fs) • Spatial and temporal contrast • coherent beam combination

  9. Technical issues: experiments White book for experiments at ELI-NP Definition and calculation of the source termsfor the experiments in the White Book Design of the target areas (including shielding)
