Ultra-short, MeV-scale laser-plasma positron source for positron annihilation lifetime spectroscopy
Thomas L. Audet, Aaron Alejo, Luke Calvin +10
Sub-micron defects represent a well-known fundamental problem in manufacturing since they can significantly affect performance and lifetime of virtually any high-value component. P…
Meter-Scale, Conditioned Hydrodynamic Optical-Field-Ionized Plasma Channels
A. Picksley, A. Alejo, R. J. Shalloo +9
We demonstrate through experiments and numerical simulations that low-density, low-loss, meter-scale plasma channels can be generated by employing a conditioning laser pulse to ion…
Guiding of high-intensity laser pulses in 100mm-long hydrodynamic optical-field-ionized plasma channels
A. Picksley, A. Alejo, J. Cowley +11
Hydrodynamic optically-field-ionized (HOFI) plasma channels up to 100mm long are investigated. Optical guiding is demonstrated of laser pulses with a peak input intensity of $6\tim…
Non-invasive characterisation of a laser-driven positron beam
Aaron Alejo, Guillermo Marrero Samarin, Richard Warwick +6
We report on an indirect and non-invasive method to simultaneously characterise the energy-dependent emittance and source size of ultra-relativistic positron beams generated during…
