![]() Studies on the IP response have typically either generated empirical formulas 14,15,17 14. and it is highly desirable to extend this to different ion species and large energy ranges. Zuegel, “ Petawatt and exawatt class lasers worldwide,” High Power Laser Sci. The existing data are limited to protons, deuterium, helium, carbon, and titanium ions, 11–17 11. The energy-dependent IP response to several ion species has been measured using ion beams from both conventional accelerators and laser-produced plasmas. However, before these sources can be seriously considered, it is important to demonstrate that sufficient numbers of highly charged heavy ions can be accelerated in an appropriate energy band for applications.Īlthough various detectors are commonly used for TPs, Fujifilm imaging plate (IP) is popular due to its extremely high sensitivity and large dynamic range, which allows the identification of individual ions. Therefore, laser-driven ion sources are a promising candidate as an injector in a heavy ion accelerator system. If the pulses interact with solid density targets, they can generate a quasi-static electric field up to 100 TV/m on the target surface, efficiently ionizing and accelerating ions over a sub-millimeter distance to energies in excess of 10 MeV/u. This is high enough to ionize heavy ions such as Ar up to the K-shell. corresponding to an oscillating electric field at the focus ∼100 TV/m. The focal intensity of such lasers can reach 10 22 W/cm 2, 11 11. Due to recent progress in laser technology, many petawatt (PW) class laser systems are being constructed all over the world for pursuing high intensity physics.

Roth et al., “ Fast ignition by intense laser-accelerated proton beams,” Phys. Kodama et al., “ Fast heating of ultrahigh-density plasma as a step towards laser fusion ignition,” Nature 412, 798 (2001). fast ignition of thermonuclear targets with laser-driven ions, 6–8 6. ![]() Bulanov et al., “ Laser ion acceleration for hadron therapy,” Phys.-Usp. This relativistic plasma enables the exploration of novel phenomena including laser-driven ion acceleration and related applications such as hadron therapy, 5 5. The free electrons are subsequently accelerated to relativistic energies, and the resultant plasma dynamics are governed by collective electromagnetic fields. the corresponding electric field at focus can significantly exceed intra-atomic fields, stripping bound electrons and generating plasma. If high power laser pulses are focused to intensities exceeding 10 18 W/cm 2, 1–4 1. ![]()
