Rf Acceleration of Ions Produced by Short Pulse Laser
An laser ion source which produces bunched ion beam is proposed to enhance an acceleration efficiency of ion accelerator front end with RFQ linac. To demonstrate a production of an initially bunched ion beam, H2 gas was ionized by short pulse laser in an RF electric field. As a result, ions captured by the RF field were observed by an ion probe.
متن کاملRadiation 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 کاملFemtosecond-pulse laser chirp compensated by cavity-mirror dispersion.
The duration of pulses generated from a simple colliding-pulse mode-locked cw dye laser is measured as a function of cavity-mirror dispersion. The optimum amount of mirror dispersion of ø (omega) congruent with + 1.8 x 10(-28) sec(2) and a suitable mirror coating for upchirp compensation are identified. The adjustment of mirror dispersion only, without additional dispersive elements, generates ...
متن کاملStability of Ion Acceleration in a Plasma Dominated by the Radiation Pressure of an Electromagnetic Pulse
The electric fields produced by the interaction of ultra-short and ultra-intense laser pulses with a thin target make it possible to obtain multiMeV , high density, highly collimated proton and ion beams with duration in the sub-picosecond range. Critical features are the efficiency of the ion acceleration process and the energy spectrum of the produced ion beam. At high laser intensities the r...
