Spectrally peaked proton beams shock accelerated from an optically shaped overdense gas jet by a near-infrared laser
George S. Hicks, Oliver C. Ettlinger, Marco Borghesi +10
We report on the generation of impurity-free proton beams from an overdense gas jet driven by a near-infrared laser ( ). The gas profile was shaped prior to…
Beamed neutron emission driven by laser accelerated light ions
S. Kar, A. Green, H. Ahmed +18
We report on the experimental observation of beam-like neutron emission with peak flux of the order of 10^9 n/sr, from light nuclei reactions in a pitcher-catcher scenario, by empl…
Selective Deuterium Ion Acceleration Using the Vulcan PW Laser
AG Krygier, JT Morrison, S Kar +17
We report on the successful demonstration of selective acceleration of deuterium ions by target-normal sheath acceleration (TNSA) with a high-energy petawatt laser. TNSA typically…
Characterisation of deuterium spectra from laser driven multi-species sources by employing differentially filtered image plate detectors in Thomson spectrometers
A. Alejo, S. Kar, H. Ahmed +23
A novel method for characterising the full spectrum of deuteron ions emitted by laser driven multi-species ion sources is discussed. The procedure is based on using differential fi…
Micron-scale Fast Electron Filamentation and Recirculation determined from Rear Side Optical Emission in High Intensity Laser-Solid Interactions
C. Bellei, S. R. Nagel, S. Kar +24
The transport of relativistic electrons generated in the interaction of petawatt class lasers with solid targets has been studied through measurements of the optical emission from…
Dynamic Control of Laser Produced Proton Beams
S. Kar, K. Markey, P. T. Simpson +16
The emission characteristics of intense laser driven protons are controlled using ultra-strong (of the order of 10^9 V/m) electrostatic fields varying on a few ps timescale. The fi…
