Dr U. Masood (HZDR)09/09/2016, 09:40Invited ReviewRadiation therapy is an important modality in cancer treatment. Particle beams, due to their superior dose profile over photons, provide higher tumor dose conformity and healthy tissue sparing. But due to the high costs and huge size of the existing ion beam therapy (IBT) facilities, particle therapy is limited to few, large centers only. Ion acceleration on micro-m scale via high intensity...Go to contribution page

Prof. Douglass Schumacher Schumacher (Ohio State University)09/09/2016, 10:20InvitedPractical application of laser based ion acceleration will require advances across a wide range of technologies extending from the laser system itself to the delivery of the ion beam. We have recently shown that the liquid crystal 8CB provides an effective and relatively inexpensive new approach to target and plasma mirror fabrication and insertion for ion acceleration. 8CB is primarily...Go to contribution page

Dr Irene Prencipe (Institute of Radiation Physics, Helmholtz-Zentrum Dresden-Rossendorf)09/09/2016, 10:45InvitedThe application of laser-driven proton beams to cancer therapy requires proton energy up to 250 MeV and delivered dose of a few Gy/min, i.e. a substantial enhancement of the current acceleration performances and operation in a repetitive regime (1-10 Hz). These requirements could be met by adopting advanced target configurations and PW-class CPA laser systems. However, thousands of targets per...Go to contribution page

Dr Andriy Velyhan (ELI Beamlines, Institute of Physics, ASCR, Prague, Czech Republic)09/09/2016, 11:10Oral contributionA solid hydrogen thin ribbon, produced by the cryogenic system ELISE (Experiments on Laser Interaction with Solid hydrogEn) target delivery system, was for the first time experimentally used at the PALS kJ-laser facility to generate intense proton beams with energies in the MeV range. This sophisticated target system operating at cryogenic temperature (~10 K) continuously producing a 62µm...Go to contribution page

Dr Lorenzo Giuffrida (ELI beamlines)09/09/2016, 11:50Oral contributionThe interaction of the laser system at LLC (Lund Laser Centre, 40 TW, 1020 W/cm2, 109 ns-contrast) with nano and micro structured thin (micrometer-scale) targets was systematically studied to control and to improve the main proton beam parameters. Mylar foils covered with nano-spheres on their rear side (with respect to the laser-target absorption surface) allowed to modulate the spatial...Go to contribution page

Dr Jan Psikal (FNSPE, Czech Technical University in Prague)09/09/2016, 12:10Oral contributionThe efficiency of ion acceleration driven by high-power femtosecond laser pulses strongly depends on the target thickness as well as on the absorption of laser pulse energy into ionized solid target. The absorption can be enhanced by using submicron structures deposited on the target laser-irradiated surface. For example, previous experiments demonstrated increased efficiency of ion...Go to contribution page

Carmen Altana (LNS)09/09/2016, 12:30Oral contributionLaser driven light-ion acceleration is being investigated for the optimization of ion cut-off energy using the ILIL facility with a laser intensity of up to 2 10^19 W/cm2. The energy spectra of different light-ions accelerated depending on structural characteristics of the target was obtained by means of a Thomson Parabola Spectrometer. Here, we focus our attention to the role of surface and...Go to contribution page

Jan Pipek (LNS)09/09/2016, 14:50Oral contributionIn this poster, we present our Geant4-based Monte Carlo application for ELIMED beam-line simulation, including its features and most important results. We have used the application to aid the design of the beam-line, to estimate various beam characteristics, and to assess the amount of secondary radiation. Currently, we are working on the user interface and overall code quality. Once finished,...Go to contribution page

Maria Cristina Battaglia (Centro Nacional de Aceleradores)09/09/2016, 15:10Oral contributionIn recent years, the use of proton and ion beams applied in cancer treatment is increasing because of their excellent depth-dose profile, exhibiting a low dose in the entrance channel and a distinct dose maximum (Bragg peak) near the end of range in tissue. However the quantification of the dose in this region is experimentally difficult and requires beam optimization and the implementation...Go to contribution page

Dario Augusto Giove (MI)09/09/2016, 15:30Oral contributionThe main goal of L3IA project is to establish an outstanding beam-line operation of a laser- plasma source in Italy. In particular, our goal is to provide the laser-driven ion acceleration with the Target Normal Sheath Acceleration (TNSA) mechanism. L3IA will be ready to operate at the ILIL installation in Pisa at a first laser driver power of 100 TW in the first half of 2017, focusing on the...Go to contribution page
