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…
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…
Dynamics of self-generated, large amplitude magnetic fields following high-intensity laser matter interaction
G. Sarri, A. Macchi, C. A. Cecchetti +15
The dynamics of magnetic fields with amplitude of several tens of Megagauss, generated at both sides of a solid target irradiated with a high intensity (? 1019W/cm2) picosecond las…
Dominance of Radiation Pressure in Ion Acceleration with Linearly Polarized Pulses at Intensities of
B. Qiao, S. Kar, M. Geissler +3
A novel regime is proposed where, employing linearly polarized laser pulses at intensities as two order of magnitude lower than earlier predicted [T. Esi…
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…
Radiation Pressure Acceleration of Thin Foils with Circularly Polarized Laser Pulses
A. P. L. Robinson, M. Zepf, S. Kar +2
A new regime is described for Radiation Pressure Acceleration of a thin foil by an intense laser beam of above 10^20 W/cm^2. Highly monoenergetic proton beams extending to GeV ener…
