As part of the ultrafast charge dynamics initiated by high intensity laser irradiations of solid targets, high amplitude EM pulses propagate away from the interaction point and are transported along any stalks and wires attached to the target. Propagation of these high amplitude pulses along a thin wire connected to a laser irradiated target was diagnosed via proton radiography technique, measuring pulse duration of ∼20 ps and pulse velocity close to the speed of light. The strong electric field associated with the EM pulse can be exploited for controlling dynamically the proton beams produced from a laser-driven source. Chromatic divergence control of broadband laser driven protons (upto 75% reduction in divergence of >5 MeV protons) was obtained using a 10 TW laser by winding the supporting wire around the proton beam axis as a helical coil structure. In addition to the focussing and energy selection, the technique has the potential to postaccelerate the transiting protons by the longitudinal component of the curved electric field lines produced by the helical coil lens.

“…The experiment was carried out at the Queen's University of Belfast (QUB) using the multi-Terawatt Chirped Pulse Amplified (CPA) laser system TARANIS. 11 This is a Ti:Sapphire-Nd:glass laser working at a wavelength of 1053 nm with a pulse duration of 700 fs and beam energy of up to 20 J. The laser was focused by a f/3 off-axis parabola (OAP) on 10 μm Al foils, leading to an intensity on target of order 10 19 W/cm 2 .…”

“…13, ps laser-irradiation typically leads to high particle numbers, allowing for example number densities up to 10 11 MeV -1 Sr -1 at 3 MeV. 11 This allows high doses to be attained in a single shot when irradiating a cell sample. An aperture slit 500 μm wide was located 10 mm behind the foil, and a dipole magnet (100 mm long, with a maximum field strength of 0.9 T) was placed 10 mm behind the slit in order to deflect the protons and disperse them according to their energies prior to the cell irradiation (see Fig.…”

The ultrashort duration of laser-driven multi-MeV ion bursts offers the possibility of radiobiological studies at extremely high dose rates. Employing the TARANIS Terawatt laser at Queen’s University, the effect of proton irradiation at MeV-range energies on live cells has been investigated at dose rates exceeding 109 Gy/s as a single exposure. A clonogenic assay showed consistent lethal effects on V-79 live cells, which, even at these dose rates, appear to be in line with previously published results employing conventional sources. A Relative Biological Effectiveness (RBE) of 1.4±0.2 at 10% survival is estimated from a comparison with a 225kKVp X-ray source

“…The second and third magnetic fields are parallel to each other and oriented in the opposite direction with respect to the first and the fourth ones. The device has been designed and already assembled at LNS and preliminary tests will be performed in order to characterize the system and to prepare the first experimental run already scheduled at the Centre for Plasma Physics at Queen's University in Belfast (UK) where the TARANIS laser system is installed 30 . Due to the field configuration, the beam is radially defocused in the first two dipoles.…”

ELIMED: a new hadron therapy concept based on laser driven ion beams

Laser accelerated proton beams have been proposed to be used in different research fields. A great interest has risen for the potential replacement of conventional accelerating machines with laser-based accelerators, and in particular for the development of new concepts of more compact and cheaper hadrontherapy centers. In this context the ELIMED (ELI MEDical applications) research project has been launched by INFN-LNS and ASCR-FZU researchers within the pan-European ELI-Beamlines facility framework. The ELIMED project aims to demonstrate the potential clinical applicability of optically accelerated proton beams and to realize a laser-accelerated ion transport beamline for multidisciplinary user applications. In this framework the eye melanoma, as for instance the uveal melanoma normally treated with 62 MeV proton beams produced by standard accelerators, will be considered as a model system to demonstrate the potential clinical use of laser-driven protons in hadrontherapy, especially because of the limited constraints in terms of proton energy and irradiation geometry for this particular tumour treatment. Several challenges, starting from laser-target interaction and beam transport development up to dosimetry and radiobiology, need to be overcome in order to reach the ELIMED final goals. A crucial role will be played by the final design and realization of a transport beamline capable to provide ion beams with proper characteristics in terms of energy spectrum and angular distribution which will allow performing dosimetric tests and biological cell irradiation. A first prototype of the transport beamline has been already designed and other transport elements are under construction in order to perform a first experimental test with the TARANIS laser system by the end of 2013. A wide international collaboration among specialists of different disciplines like Physics, Biology, Chemistry, Medicine and medical doctors coming from Europe, Japan, and the US is growing up around the ELIMED project with the aim to work on the conceptual design, technical and experimental realization of this core beamline of the ELI Beamlines facility
