Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

Pair production by a strong wakefield excited by lasers in a magnetized plasma

Rios, L. A. and Serbeto, A. and Mendonca, J. T. and Shukla, P. K. and Bingham, R. (2006) Pair production by a strong wakefield excited by lasers in a magnetized plasma. Journal of Experimental and Theoretical Physics, 103 (1). pp. 47-53. ISSN 1063-7761

The production of electron-positron pairs due to accelerated electrons in a magnetized plasma is considered. The high-energy electrons are produced during laser-plasma interactions in the presence of spontaneously produced magnetic fields. By using a classical fluid description, we analyze the generation of electrostatic wakefields at the plasma wave-breaking limit and estimate the number of produced pairs for different situations. We note that, in some cases, the presence of the magnetic field can increase the number of produced pairs.
