World class computing and information science research at Strathclyde...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by University of Strathclyde researchers, including by researchers from the Department of Computer & Information Sciences involved in mathematically structured programming, similarity and metric search, computer security, software systems, combinatronics and digital health.

The Department also includes the iSchool Research Group, which performs leading research into socio-technical phenomena and topics such as information retrieval and information seeking behaviour.

For almost 60 years, physicists have used strong, large-scale electric fields to accelerate charged subatomic particles. Unfortunately, these conventional particle accelerators, RF linacs, have reached a limit: at an electric field strength of about 107 V m-1, the support structures break down — sparks fly, short-circuiting the accelerator. So, in order to reach higher particle energies one is forced to build ever larger linear accelerators, or bend the particles into a circular path using magnets (which produces another problem, as the particles then radiate away much of their energy). In theory, this electric-field problem can be overcome by plasma particle accelerators, because plasma, as an ionized medium, has already broken down and is therefore not susceptible to electron dissociation. Plasma waves can generate accelerating electric fields thousands of times greater than the most powerful conventional accelerators. And in Physical Review Letters , Amiranoff and colleagues now report1 an experiment that brings the 'table-top' plasma accelerator a step closer to reality.
