Laser-Plasma Acceleration: Status from Italy

Danilo Giulietti Physics Department of the University and INFN, Pisa, Italy PLASMONX National Representative

The beginning of the Italian activity in LPA

In the 2000 the Pisa group performed the first experiments in LPA at LOA. After that INFN manifested interest in our activity and Sergio Bertolucci, at that time Director of the LNF invited me for a seminar. The LNF colleagues were very shocked when I was speaking of acceleration gradients of several 100GV/m !

The birth of PLASMONX

Later on NTA Commission (whose chairman was Sergio Bertolucci), after considering a CDR of a project devoted to the development NTA based

• n LPA and innovative X-gamma sources based
• n TS, launched in the 2005 the Strategic Project
• PLASMONX. The project takes advantages from

the complementary expertises of INFN and CNR in the fields of HEP and LASER-PLASMA Interactions respectively.

QuickTime™ and a decompressor are needed to see this picture.

The first experiments of SI-LPA offer also the possibility to test the LASER main parameters

External injection

Wed 4/5 11:00, LPA/EI by L.Serafini We intend also to inject monochromatic e-bunches into LPW excited by the powerful LASER to reduce the energy spread of the accelerated electrons. The experiment is challenging due to the required synchronization between LASER and LINAC (10fs) and the shortness of the e-bunches (few µm) with respect to the plasma wavelength.

Due to the high control on the LINAC photo- injector we intend to accelerate electrons in a plasma wave resonantly excited by a train of e-bunches

Human Resources and expertises

*Complementary expertises from HEP and LASER-Plasma community *Major Italian Universities involved *International collaborations

Goals and planned activity

• Control of LPA mechanism
• Development of new targets
• Multi stages
• External Injection
• Coherent multi e-bunches
• X-gamma secondary sources
• LPA of ions

ELI would be the first infrastructure dedicated to the fundamental study of laser-matter interaction in a new and unsurpassed regime

• f laser intensity: the ultra-relativistic regime (IL>1023 W/cm2).

The infrastructure would serve to investigate a new generation of compact accelerators delivering energetic particle and radiation beams

• f femtosecond (10-15s) to attosecond (10-18s) duration.

ELI would afford wide benefits to society ranging from improvement

• f oncology treatment, medical imaging, fast electronics and our

understanding of aging nuclear reactor materials to development of new methods of nuclear waste processing.
