“…This effect and the use of optimal laser pulse shape provide a new approach for great enhancing the energy of laser accelerated ions. Carried out [16] and forthcoming laboratory experiments on the laser plasma interaction in the RPDA regime will contribute to the development of the laboratory astrophysics discipline [34,35] and to studying of the "Light Sail" mechanism for spacecraft propulsion.…”

“…A foil accelerated to relativistic energies by a laser pulse can act as a relativistic flying mirror for frequency up-shift and intensification of a reflected counter-propagating light beam [15]. An indication of the effect of the radiation pressure on bulk target ions is obtained in experimental studies of plasma jets ejected from the rear side of thin solid targets irradiated by ultraintense laser pulses [16].…”

The energy of the ions accelerated by an intense electromagnetic wave in the radiation pressure dominated regime can be greatly enhanced due to a transverse expansion of a thin target. The expansion decreases the number of accelerated ions in the irradiated region increasing the energy and the longitudinal velocity of remaining ions. In the relativistic limit, the ions become phase-locked with respect to the electromagnetic wave resulting in the unlimited ion energy gain. This effect and the use of optimal laser pulse shape provide a new approach for great enhancing the energy of laser accelerated ions.2

“…Thus we consider two mechanisms of laser ion acceleration relevant to these targets and able to provide necessary peak energy. In the case of a very thin liquid target it is RPA [17,26,27], and in the case of a gas target it is MVA [18,19,28].…”

The laser driven acceleration of ions is considered a promising candidate for an ion source for hadron therapy of oncological diseases. Though proton and carbon ion sources are conventionally used for therapy, other light ions can also be utilized. Whereas carbon ions require 400 MeV per nucleon to reach the same penetration depth as 250 MeV protons, helium ions require only 250 MeV per nucleon, which is the lowest energy per nucleon among the light ions (heavier than protons). This fact along with the larger biological damage to cancer cells achieved by helium ions, than that by protons, makes this species an interesting candidate for the laser driven ion source. Two mechanisms (magnetic vortex acceleration and hole-boring radiation pressure acceleration) of PW-class laser driven ion acceleration from liquid and gaseous helium targets are studied with the goal of producing 250 MeV per nucleon helium ion beams that meet the hadron therapy requirements. We show that He 3 ions, having almost the same penetration depth as He 4 with the same energy per nucleon, require less laser power to be accelerated to the required energy for the hadron therapy.

“…With currently accessible intensities (in excess of 10 20 W cm −2 ) of short pulse lasers, ions can be accelerated to high energies (up to several tens of MeV/nucleon) with promising beam parameters for several potential applications in science, industry and healthcare [1][2][3] . A number of acceleration mechanisms, such as Target Normal Sheath Acceleration (TNSA) 4,5 , Radiation Pressure Acceleration (RPA) [6][7][8][9] , Break-Out Afterburner (BOA) 10,11 , are objects of intense investigation both experimentally and theoretically in order to improve the beam parameters. a) Electronic mail: s.kar@qub.ac.uk Laser accelerated ion beams from solid targets are typically multi-species, either due to the chemical composition of the target material or due to the layer of contamination over the target (typically composed of water vapour and hydrocarbons) 12,13 .…”

A novel method for characterising the full spectrum of deuteron ions emitted by laser driven multi-species ion sources is discussed. The procedure is based on using differential filtering over the detector of a Thompson parabola ion spectrometer, which enables discrimination of deuterium ions from heavier ion species with the same charge-to-mass ratio (such as C 6+ , O 8+ , etc.). Commonly used Fuji Image plates were used as detectors in the spectrometer, whose absolute response to deuterium ions over a wide range of energies was calibrated by using slotted CR-39 nuclear track detectors. A typical deuterium ion spectrum diagnosed in a recent experimental campaign is presented, which was produced from a thin deuterated plastic foil target irradiated by a high power laser.
