Abstract: We report on the development of radiation and electron sources based on laser-plasma acceleration for biomedical and nuclear applications, using both the table top TW laser at ILIL and the 220 TW FLAME laser system at LNF. We use the ILIL laser to produce wakefield electrons in a self-focusing dominated regime in a mm scale gas-jet to generate large, uniform beams of MeV electrons for electron radiography and radiobiology applications. This acceleration regime is described in detail and key parameters are given to establish reproducible and reliable operation of this source. We use the FLAME laser to drive laser-plasma acceleration in a cm-scale gas target to obtain stable production of >100 MeV range electrons to drive a Thomson scattering gamma-ray source for nuclear applications.

More Information: The results presented here were obtained during experimental campaigns carried out at the ILIL laser installation at INO-CNR and at the FLAME Laser installation at LNF-INFN. The work was supported by INFN New Acceleration Techniques (NTA) committee and by the High Field Photonics Unit at INO-CNR. We thank the staffs of the LNF Accelerator and Technical Divisions for the support during the FLAME commissioning. Special thanks go to Oreste Cerafogli and Valerio Lollo at LNF for their continuous effort and proactive collaboration in the commissioning operations. We wish to thank Mario Calvetti for his enthusiastic and enlightening support during the FLAME comm issioning. Special thanks go to Paolo Ferrara of INO-CNR for attentive reading of the manuscript.
