Selective Deuteron Acceleration using Target Normal Sheath Acceleration
… species accelerated is the lightest present on a target surface typically contaminated with hydrocarbons and water: protons. This work elucidates a method of in-situ cryogenic coating of heavy ice on ultra-intense laser targets and experimental confirmation of the dominant acceleration of ~MeV …

Real-time observation of particle interactions in matter using laser-driven accelerators
… and protons generated via Bremsstrahlung and Target Normal Sheath Acceleration (TNSA) respectively, as the pump source and chirped light with an adjustable wavelength as the probe. The role of localised and delocalised particle interactions within ordered and disordered media is examined in …

The role of near time coherent contrast on ultrafast laser driven radiation sources
… prepulse introduced into a set-up for ion acceleration via Target normal sheath acceleration (TNSA). Using the optical streaking method, ultrafast absorption dynamics induced by the accelerated protons in H_20 are observed. By changing the arrival of the controlled prepulse the maximum …

Laser-Driven Particle Acceleration - Improving Performance Through Smart Target Design
Laser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons …

Schemes of ion acceleration employing high energy, petawatt laser pulses
… experimental and numerical investigations of ion acceleration employing high energy, picosecond laser pulses. In two separate campaigns on the petawatt arm of the Vulcan laser system, novel laser and target parameters were implemented to explore schemes of ion acceleration beyond the well …

Multispecies ion acceleration from intense laser interactions with thin foils
… and demonstration of novel laser driven ion acceleration mechanisms is key to overcoming the limitations of both well understood laser based processes and becoming competitive with conventional particle accelerators. This thesis presents two methods of enhancing the ion energies achievable in …
