Dr. Martin Prest: Martin received his PhD from the University of Warwick in 2001 where he studied SiGe MOSFETs; germanium was used to strain the lattice, forming quantum wells in the device with high carrier mobility, with application in pMOS devices. Interface-trap measurements and carrier scattering models were used to show that Ge segregation and interface roughness were limiting factors on device performance. SiGe pMOSFETs were found to have low 1/f noise.

This led to the development of RIXSCam, an EM-CCD camera that applies post processing algorithms to significantly improve the resolution of the detector at SAXES which is now being installed in RIXS spectrometers around the world. Following his PhD, Matthew carried out a post-doc to characterise and space-qualify the CIS115, a CMOS APS for the JANUS camera on ESA's JUICE mission, destined for launch in 2022. Matthew is now working on the CCDs for the Soft X-ray Imager on SMILE, combining his interests of X-ray detection in CCDs with understanding and mitigating the effects of space radiation damage observed in solid-state imaging devices.

Visiting Researchers

Prof. David Burt: David is a world expert in the design and manufacture of semiconductor devices. He has worked at GEC Hirst Research labs and e2v throughout the history of CCDs, and has introduced many innovative changes to CCD design for improved performance. David is seconded from e2v part-time in the group and assists with PhD student and post-doctoral researcher training, and in addition supports the research activities of the group.

Prof. Mike Cruise: Mike Cruise has worked at UCL, RAL and the University of Birmingham on many space projects over the past five decades. He started his career at MSSL developing X-ray astronomy imaging and detector technologies. In 1986 Mike moved to RAL as Astrophysics Group Leader , later becoming Associate Director for Space Science. In 1983 he had developed an interest in General Relativity and gravitational waves and in 1995 was appointed to the chair of Astrophysics and Space Research at the University of Birmingham where he founded the Gravitational Wave Group that played a significant role in the discovery announced in 2016. Mike has chaired many space science committees in the UK and internationally and is currently President of the Royal Astronomical Society. He continues an interest in the interaction of electromagnetic and gravitational waves.

Prof. Chris Damerell: Starting as a grad student in 1962 (moving from Cape Town U to Oxford U) Chris' early career (Nimrod at RAL, AGS at BNL, PS at CERN) provided him with a great opportunity to learn the skills of an experimental physicist, working in groups with excellent and supportive leaders. In 1970, he started to develop micron precision tracking detectors, in contrast to then-current limits of ~100 μm possible using drift chambers. The physics motivation was shaky, but his group came to the fore after the discovery of charmed particles (with measurable lifetimes of ~10-13 sec) in 1974. His group pioneered pixelated vertex detectors in CERN (fixed target) then SLAC (SLC e+ e- collider). After the great physics success at SLD, he has worked to develop even more adventurous vertex detectors for future colliders, and recently expanded his horizons to consider novel tracking detectors using CMOS APS arrays (barrel radii ~2 m, ~30 Gpixels). The hope is to replace the current generation of microstrip-based tracking detectors, which are fairly opaque and cause many particles to interact before reaching the outer detectors. Chris is a visiting professor in the CEI and as well as passing on his knowledge and experience to all members of the group, is currently working with Konstantin Stefanov and David Burt on CCD development for LSST.

Dr. Paul Jerram: Paul has worked in the imaging division of Teledyne-e2v for nearly 25 years following a Ph.D. in atomic physics at University College London and a number of roles in different technology areas within e2v.
