Open Access: World leading research into plasma physics...

Strathprints makes available scholarly Open Access content by researchers in the Department of Physics, including those researching plasma physics.

Plasma physics explores the '4th' state of matter known as 'plasma'. Profound new insights are being made by Strathclyde researchers in their attempts to better understand plasma, its behaviour and applications. Areas of focus include plasma wave propagation, non-linear wave interactions in the ionosphere, magnetospheric cyclotron instabilities, the parametric instabilities in plasmas, and much more.

Based on the REF 2014 GPA Scores, Times Higher Education ranked Strathclyde as number one in the UK for physics research.

Abstract

Narrow band undulator radiation tuneable over the wavelength range of 150–260 nm has been produced by short electron bunches from a 2 mm long laser plasma wakefield accelerator based on a 20 TW femtosecond laser system. The number of photons measured is up to 9 × 106 per shot for a 100 period undulator, with a mean peak brilliance of 1 × 1018 photons/s/mrad2/mm2/0.1% bandwidth. Simulations estimate that the driving electron bunch r.m.s. duration is as short as 3 fs when the electron beam has energy of 120–130 MeV with the radiation pulse duration in the range of 50–100 fs.
