Microengineering laser plasma interactions at relativistic intensities
S. Jiang, L. L. Ji, H. Audesirk +8
We report on the first successful proof-of-principle experiment to manipulate laser-matter interactions on the microscale using highly ordered Si microwire arrays. The interaction…
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…
Enhancing Bremsstrahlung Production From Ultraintense Laser-Solid Interactions With Front Surface Structures
S. Jiang, A. G. Krygier, D. W. Schumacher +2
We report the results of a combined study of particle-in-cell and Monte Carlo modeling that investigates the production of Bremsstrahlung radiation produced when an ultraintense la…
On The Origin of Super-Hot Electrons from Intense Laser Interactions with Solid Targets having Moderate Scale Length Preformed Plasmas
A. G. Krygier, D. W. Schumacher, R. R. Freeman
We use PIC modeling to identify the acceleration mechanism responsible for the observed generation of super-hot electrons in ultra-intense laser-plasma interactions with solid targ…
The Effects of Front-Surface Target Structures on Properties of Relativistic Laser-Plasma Electrons
S. Jiang, A. G. Krygier, D. W. Schumacher +2
We report the results of a study of the role of prescribed geometrical structures on the front of a target in determining the energy and spatial distribution of relativistic laser-…
