There are high costs and high risks associated with the consequences of space weather events, as insurance companies recognise.
Intense space weather events are triggered by the explosive release of energy stored in the Sun’s magnetic field.
A strong burst of electromagnetic energy reaches the Earth with the potential to disrupt many of our fundamental services, such as satellite and aviation operations, navigation, and electricity power grids. Telecommunications and information technology are likewise vulnerable to space weather.
Research by the Radio and Space Plasma Physics Group in the University of Leicester’s Department of Physics and Astronomy helps our understanding of coupling processes between the solar wind and the Earth’s magnetosphere by allowing the observation of the consequences of space weather with an unprecedented resolution.
Postgraduate researcher James Borderick explained: “We introduce the importance of utilising ground-based measurements of the near space environment in conjunction with spacecraft observations and then proceed to explain the direct influences of space weather on our own technological systems.
“Utilising our new radar modes and an international array of ground-based and space-based instruments, we are ever increasing our understanding of the countless phenomena associated with the solar-terrestrial interaction.”
“One day this may lead us to the accurate predictions of the occurrence and consequences of phenomena such as Coronal Mass Ejections (CMEs), and perhaps an active defence.”
The use of ground-based radars for observations of ionospheric and magnetospheric dynamics is well established. The Super Dual Auroral Radar Network (SuperDARN) consists of networks of High-Frequency radars surrounding the northern and southern poles, which have yielded extensive data on our near space environment.
A new “double pulse” pulse sequence has been implemented on the Radio Space Plasma Physics Group’s Co-operative UK Twin Located Auroral Sounding System (CUTLASS) radars. CUTLASS forms part of SuperDARN.
The new sounding mode enhances the temporal resolution of observations of plasma irregularities within the ionosphere. It increases the cadence of pulse transmissions within the same transmission time as the standard SuperDARN-operating mode.
As an undergraduate physicist at the University of Leicester, he was awarded both the Philips and Departmental Prizes in Physics and achieved the highest mark of all 4th year undergraduates in his final year. Between his penultimate and final years, he obtained a position on the prestigious SURE research programme where he conducted a preliminary investigation on the coupling processes between the Solar Wind and the Earth’s magnetic field. He has just recently presented his Double Pulse findings at the SuperDARN Conference of 2008 in New South Wales, Australia. In the future, he hopes to continue in academia, forwarding science and simultaneously enthusing the next generation of scientists.
The research is being presented to the public at the University of Leicester on Thursday 26th June. The Festival of Postgraduate Research introduces employers and the public to the next generation of innovators and cutting-edge researchers, and gives postgraduate researchers the opportunity to explain the real world implications of their research to a wide ranging audience.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
