Research Expertise

Nano-metrology of synchrotron X-ray optics and associated opto-mechanics and motion stages is my area of research.

My research work focuses on development of new metrology instrumentation and techniques to help to create next-generation X-ray optics for synchrotron beamlines. Improved X-ray optics are of direct benefit to Diamond's beamlines to produce more intense, focusssed X-ray beams for science.
I am also involved in research to create next-generation metrology instruments and techniques.

My current role at Diamond entails following parts:
  • Overseeing operations in the Optics & Metrology cleanroom lab and Precision Metrology lab (PML).
  • Site acceptance testing of X-ray mirrors.
  • Installing and optimising the mirrors into their beamline opto-mechanical holders.
  • Provide assistance during installation of X-ray optics on to the beamlines.

Biography

After completing a PhD in X-ray surface diffraction and a MPhys degree in Physics at the University of Leicester, Simon joined Diamond full-time in Sept 2003 (he had earlier worked part-time for Diamond since 2002). Initially he provided scientific support to the Science Directors, before joining the Optics & Metrology group in 2005. He has since helped to design, build, and equip the Optics & Metrology cleanroom for characterising X-ray optics. In 2011, he also played a major role in designing and equiping the Precision Metrology Lab to test motorised stage used to rotate and translate important beamline components including X-ray optics, samples, and detectors.
