Almost fully stripped Fe ions accelerated up to 0.9 GeV are demonstrated with a 200 TW femtosecond high-intensity laser irradiating a micron-thick Al foil with Fe impurity on the surface. An energetic low-emittance high-density beam of heavy ions with a large charge-to-mass ratio can be obtained, which is useful for many applications, such as a compact radio isotope source in combination with conventional technology.

Laser driven ion acceleration

Daido, Hiroyuki

Purazuma, Kaku Yugo Gakkai-Shi, 81(4), p.261 - 269, 2005/04

This paper reviews the recent activities of laser-driven ion generation studies. First, the mechanisms of the ion generation are described including the plasma sheath model which describes energetic proton generation driven by sub-ps high energy lasers. A pre-pulse plays a significant role especially for the fs laser driven ion generation. The under-dense plasma model described here is one of the mechanisms, which utilize pre-pulses. The quasi-mono-energetic ion beam obtained theoretically and computationally is reviewed. Then the experimental results on the ion generation driven by sub-ps large energy lasers as well as fs lasers are reviewed. Although lower maximum proton energy and efficiency compared with those driven by sub-ps lasers at present, the results given by the fs lasers are precisely described because the fs lasers may be closer to real applications. Finally the present project on the ultra small ion accelerator development for cancer therapy and related topics are reviewed.

The contemporary radiofrequency accelerator technology provides radio-isotope beams for the research. However, the existing technology now faces difficulties in exploring the further frontiers. One of the solutions might be brought by the combination of the state of the art high intensity short pulse laser system and the nuclear measurement technique. Recent progress of the laser technology brought table-top lasers with focused intensity up to 10$$^{21}$$ Wcm$$^{-2}$$ with only less than 10 J of energy on target. By the interaction with the solid density target, the laser can extract heavy ions in multi-charged state and low emittance, independently on the chemical properties of the target material. We propose Laser-driven Exotic Nuclei extraction-acceleration methods (LENex), in which the exotic nuclei which are the products in the target by the bombardment of the external ion beam, are extracted away by a femtosecond petawatt laser pulse in the form of highly-charged and high energy beam. As a proof-of-experiment of the LENex scheme, we demonstrate the extraction of the almost fully stripped iron ions with the energies of 0.9 GeV. by J-KAREN laser system.

Laser wakefield acceleration is regarded as a basis for the next-generation of charged particle accelerators. In experiments, it has been demonstrated that LWFA is capable of generating electron bunches with a very short duration of the order of ten femto-seconds. The oscillation of the electron beam by the transverse wakefield and the electric field of the laser pulse generates X-rays. The X-rays will be an useful tool for measurement of the ultrafast phenomena. The experiments have been performed with a Ti:sapphire laser system. The laser pulses with 160 mJ energy are focused onto a 3-mm-diameter helium gas-jet. The pulse width of the laser pulse is 40 fs. We observe two types of the electron oscillation. One of the oscillation is due to the transverse plasma wake. The other is due to the electric field if the laser pulse. The electron beam oscillation should be generated ultra-short X-rays. The X-rays will be an useful tool for measurement of the ultrafast phenomena.
