Production of energetic ion beams using high intensity lasers | |
|
||
| Ion acceleration by irradiating ultra-thin foils or gas jets with high intensity laser pulses has been receiving much attention lately. Using this technique, beams of protons with energies up to ~60 MeV have been observed. Although not confirmed yet, it is predicted that the energy can be increased by a factor of 5-10. At the moment the particle distributions produced by such accelerators hardly allows the use of the beam produced for applications like medical isotope production but steady progress in the field might change the situation in the near future. First experiments irradiating cell lines for cancer research with laser accelerated ions have been successfully performed and further experiments at 4 MeV to fit the requirements for radiobiology experiment have been proposed. Within the next 5 years laser based injectors delivering beams of ions at high intensity and repetition rate at energies of 30-40 MeV to conventional linac seem possible. The status of laser accelerated ions together with possible applications will be presented and an outlook on further developments given. | ||
