Dr. Chris Jeynes | Independent scholar, Tredegar, Wales | United Kingdom
Professor Christopher Jeynes is an internationally respected physicist known for his pioneering work in ion beam analysis (IBA), thin film characterisation, and precision materials metrology. Based for most of his career at the University of Surrey’s Ion Beam Centre, he played a leading role in developing IBA into a world-class analytical technique for quantitative materials characterisation. He co-developed the IBA DataFurnace, a globally recognised analytical code, and was the first to demonstrate one-percent absolute accuracy in Rutherford backscattering spectrometry, establishing it as a primary reference method for determining material composition. His work led to the first ISO 17025 accreditation of an IBA laboratory as a calibration facility. Professor Jeynes has contributed extensively to international scientific standards and data quality through collaborations with the International Atomic Energy Agency (IAEA) and the Bureau International des Poids et Mesures (BIPM). He has published more than 300 papers and several influential book chapters shaping the field of ion beam techniques. His research emphasises self-consistent data fitting to minimise systematic uncertainty and improve analytical reliability. Beyond IBA, he has been instrumental in developing the emerging discipline of Quantitative Geometrical Thermodynamics with Dr. Mike Parker, linking geometry and thermodynamics to new theoretical insights. His contributions have had lasting impact on materials science, analytical accuracy, and interdisciplinary physical theory.
