I have to report the very sad news that Professor John Forty, the founding professor of the Department of Physics, passed away on Sunday 14th May aged 94.

The leading position that the Department holds today is due, in no small measure, to the vision and leadership that John showed in setting up the Department in the 1960s, from his choice of staff and their research areas to the design of a building that has remained "fit for purpose" for many decades, despite the many changes in use that have occurred.

More information will be provided when available.

Head of Department

Congratulations to Dr Karolos Potamianos who has been awarded 拢287,845 from Science and Technology Facilities Council (STFC) for a research project titled 'Expanding the timing frontier: precision timing for particle tracking and identification.'

The funding will permit the procurement of a 12 GHz signal generator, a fast oscilloscope (<8ps per sample), and a logic analyser. These will enable the proper characterisation of ultra-fast silicon detectors and associated readout at realistic operating conditions, in particular enabling precise measurements of their (ultra-fast) response signals.

The research will be led by Dr Karolos Potamianos. He said,

"The use of fast silicon in collider detectors offers many new opportunities, as high-precision timing information enables distinguish between collisions occurring very close in space but well-separated in time. This will greatly help mitigate the effect of overlapping proton-proton interactions (pileup) at the High-Luminosity LHC. It is thus essential that we can properly characterise these detectors, which the procured equipment will enable. However, challenges such as ensuring proper operation of the detectors in a tough radiation environment and that sufficient bandwidth is available to transfer data out of the detector remain to make these detectors a reality at the LHC.鈥�

STEM for Britain is a major scientific poster competition and exhibition with an aim to give members of both Houses of Parliament an insight into the outstanding research work being undertaken in UK universities by early career researchers and was held at the House of Commons on Monday 6th March, 2023. Dr Lauren DoyleLink opens in a new window was selected as a finalist within the Physics category, to represent her research on stellar flares from solar-type and low mass stars where she found these events don鈥檛 correlate with starspots like they do on the Sun. Overall, this suggests other stars have much more complex surfaces compared to the Sun which posses questions when thinking about the habitability of other planets. The event was attended by people from across the UK with representation from many institutions and organisations including The Institute of Physics and 糖心TV. During the event, Lauren got the opportunity to chat to lots of researchers across Physics, Mathematics and Chemistry about their research, with lots of interest from the judges about her own research. Although Lauren didn't place in the competition she told us:

"Despite this, I am really glad I went as it was an amazing experience where I was one of 20 finalists selected to represent Physics research in the UK. I was extremely proud to represent the Physics department at 糖心TV University and hope that others from the department will apply to attend next year."

Congratulations to Lauren for representing the department and her research at the event.

Elizabeth who works in the Ultrasound Group presented an update of her results to the NDA and the wider nuclear industry, showing how the pressure inside a welded steel container could be measured using non-contact acoustic transducers to excite and detect the natural resonant modes of the container via the electromagnetic Lorentz mechanism. The pressure inside the containers can increase due to radioactive decays and chemical reactions of the material inside the sealed containers, and it is important to be able to measure if the pressure becomes too high. Using a combination of Finite Element (FE) modelling, optical vibrometer and EMAT measurements, Elizabeth has proved that the resonant modes that she is experimentally measuring, correspond exactly to those predicted by the FE models, and that generally the frequency of those modes increase as pressure inside the container increases. Elizabeth plans to develop a prototype system for trials in the nuclear industry, under an EPSRC IAA project that she will start later this year.
