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…
Calibration of Time Of Flight Detectors Using Laser-driven Neutron Source
S. R. Mirfayzi, S. Kar, H. Ahmed +17
Calibration of three scintillators (EJ232Q, BC422Q and EJ410) in a time-of-flight (TOF) arrangement using a laser drive-neutron source is presented. The three plastic scintillator…
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…
A proposal for testing subcritical vacuum pair production with high power lasers
G. Gregori, D. B. Blaschke, P. P. Rajeev +11
We present a proposal for testing the prediction of non-equilibrium quantum field theory below the Schwinger limit. The proposed experiments should be able to detect a measurable n…
