CNR: Italian Research Network “Extreme Light Infrastructure” ELI -Italy Consiglio Nazionale delle Ricerche (CNR)  “Istituto di Fotonica e Nanotecnologie” (IFN, Milano -Padova)  “Istituto Nazionale di Ottica (INO, Firenze -Pisa) Aims EuroNNAc2011  Forefront research on lasers and photonics  Link to pan-european research infrastructures (ELI)  Training of qualified personnel on lasers and photonics  Technology transfer to high tech SME (national and international)

ELI-Italy - Research Topics  High energy radiation and particles  Optimization of electron laser driven accelerator   -ray source by laser accelerated electrons  Radiotherapy applications  Attosecond science and applications  Schemes for attosecond pulse generation in XUV  Diagnostics for attosecond pulse characterization  XUV beam lines for attosecond spectroscopy of atoms and molecules EuroNNAc2011  Frequency combs  Frequency comb from Near-IR to IR  Spectral purity and tunability of laser sources locked to the combs  Solid state and fiber amplifiers of frequency combs

OUR PLANS FOR LPA OUR PLANS FOR LPA Pursue LPA in the medium term to a) establishing LPA for future high energy accelerators (collaboration with INFN – PLASMONX project) ; • Injector-like approach : seek conditions for compact , “all - optical” ultra-high gradient, multi-GeV, 10 Hz accelerator under controlled laser- plasma interaction conditions; • Implement plasma schemes (ext. inj., comb.) to enhance existing conventional accelerators; EuroNNAc2011 b) bio-medical (industrial) applications of table-top configurations (@CNR installation in Pisa); • Explore the physics of LPA at TW level and 10s of MeVs and find optimum conditions for efficient acceleration with long term operation and stable averaged output applicable to therapy (e.g. IORT).
