Radiation Pressure effects on ion Acceleration on the GEMINI laser
We report on the absolute calibration of amicro channel plate (MCP) detector, installed asdetector in a Thomson parabola spectrometer. Thecalibration delivers the relation between a registeredcount numbers in the CCD camera (on which the MCPphosphor screen is imaged) as a result of the impact ofan ion beam onto the MCP. The particle response ofthe whole detection...
متن کاملIssues in Radiation Pressure Acceleration
Radiation Pressure Acceleration by circularly polarized laser pulses has been proposed and widely investigated theoretically as a promising scheme for efficient generation of ions. In particular, the use of ultrathin targets may allow to reach energies per nucleon beyond the GeV range. The first, recently reported experiments appear to confirm the basic mechanism and i...
متن کاملIon acceleration in multispecies targets driven by intense laser radiation pressure.
The acceleration of ions from ultrathin foils has been investigated by using 250 TW, subpicosecond laser pulses, focused to intensities of up to 3 × 10(20) W cm(-2). The ion spectra show the appearance of narrow-band features for protons and carbon ions peaked at higher energies (in the 5-10 MeV/nucleon range) and with significantly higher flux than previously reported. The spectral features an...
متن کاملRadiation-pressure acceleration of ion beams driven by circularly polarized laser pulses.
We present experimental studies on ion acceleration from ultrathin diamondlike carbon foils irradiated by ultrahigh contrast laser pulses of energy 0.7 J focused to peak intensities of 5x10(19) W/cm2. A reduction in electron heating is observed when the laser polarization is changed from linear to circular, leading to a pronounced peak in the fully ionized carbon spectrum at the optimum foil th...
متن کاملRadiation pressure acceleration of thin foils with circularly polarized laser pulses
A new regime is described for radiation pressure acceleration of a thin foil by an intense laser beam of above 1020 W cm. Highly monoenergetic proton beams extending to giga-electron-volt energies can be produced with very high efficiency using circularly polarized light. The proton beams have a very small divergence angle (<4). This new method allows the construction of ultracompact proton and...
