Production of radioactive nuclides by energetic protons generated from intense laser-plasma interactions
Applied Physics Letters 78:1 (2001) 19-21
Abstract:
Nuclear activation has been observed in materials exposed to the ablated plasma generated from high intensity laser-solid interactions (at focused intensities up to 2 × 1019 W/cm2) and is produced by protons having energies up to 30 MeV. The energy spectrum of the protons is determined from these activation measurements and is found to be consistent with other ion diagnostics. The possible development of this technique for "table-top" production of radionuclides for medical applications is also discussed.Ultrahigh-intensity laser-produced plasmas as a compact heavy ion injection source
IEEE Transactions on Plasma Science 28:4 (2000) 1110-1115
Abstract:
The possibility of using high-intensity laser-produced plasmas as a source of energetic ions for heavy ion accelerators is addressed. Experiments have shown that neon ions greater than 6 MeV can be produced from gas jet plasmas, and well-collimated proton beams greater than 20 MeV have been produced from highintensity laser solid interactions. The proton beams from the back of thin targets appear to be more collimated and reproducible than are high-energy ions generated in the ablated plasma at the front of the target and may be more suitable for ion injection applications. Lead ions have been produced at energies up to 430 MeV. © 2000 IEEE.22pWE-10 高速点火研究3 : High density relatlvistic electron propagation in high density plasma
