Status and ongoing work

Present situation• ADONIS (Laser driver) operating at 2.5 J – 10 Hz

• Two 10 Hz compressed IR beamlines available : 1.4 J / 1 ps to 100 ps (SXRL) 100 mJ / 40 fs (IR probe or HHG pumping)

• 100 J / 0.1 Hz pump lasers ready with DKDP, LBO installed soon (160 J expected)→ 4 beams (2 tables) will be shared with ILE (LUIRE & APPOLON)

• 10 Hz SXRL and HHG under development→ expected with optimized performances before end 2010 (GRIP &

DGRIP)

• Full Command-control of the entire installation under development→ expected before summer 2011 (coll. Amplitude Technologies)

Coming soon• 10 Hz SXRL beamline opening for experiments (coll.) → beginning 2011

• 40 J – 0.1 Hz amplifier (8 pump beams) & compressor → planned for beginning 2011
