Transversely pumped laser driven particle accelerator

Tanner Nutting, Nicholas Ernst, Alexander G. R. Thomas +1

We present a new acceleration scheme capable of accelerating electrons and ions in an underdense plasma. Transversely Pumped Acceleration (TPA) uses multiple arrays of counter-prop…

Extended X-ray absorption spectroscopy using an ultrashort pulse laboratory-scale laser-plasma accelerator

B. Kettle, C. Colgan, E. Los +21

Laser-driven compact particle accelerators can provide ultrashort pulses of broadband X-rays, well suited for undertaking X-ray absorption spectroscopy measurements on a femtosecon…

Orbital angular momentum enhanced laser absorption and neutron generation

Nicholas Peskosky, Nicholas Ernst, MiloÅ¡ Burger +5

We experimentally demonstrate enhanced absorption of near relativistic optical vortex beams in $D_{2} O$ plasmas to generate a record fast-neutron yield of $1.45 \times 1 0^{6}$ …
