Autorenporträt

Peter Coates joined NPL in 1966, having gained a BSc at Cambridge and a PhD at Imperial College working with shock tubes. On joining the National Physical Laboratory he initially constructed ultra-fast timing circuits for measuring the time of emission of radiation from atoms, a skill he took with him when he joined the temperature section to measure the emission of photons from poorly radiating surfaces by counting individual photons. He transferred to the Temperature Section in 1972, to apply his expertise in photon counting to the NPL primary photoelectric pyrometer built by T. J. Quinn and M. Ford. He was able to make significant improvements in precision use of photomultipliers in the days before silicon photodiodes became established. He and his colleagues, Terence Chandler and John Andrews, also improved the performance and use of pyrometric lamps, including feedback stabilisation of the radiance, and they made the first and most accurate determination of the freezing temperature of palladium for many years. Peter succeeded Terry Quinn as Section head in 1975, while continuing his work in pyrometry. He was an excellent theorist, and produced two or three seminal papers in pyrometry, notably exposing the weaknesses of multiwavelength methods, which had been much trumpeted as overcoming the difficulty of unknown emissivity, showing that it is fundamentally based on an unjustified extrapolation to zero wavelength and that passive techniques alone could not solve the problem. In the early 1980s, dissatisfied with the frustrations of management, he made a second career change and moved to the NPL Time and Frequency group, where he remained until his retirement. He meanwhile drafted most of an authoritative and muchneeded book on 'Radiation Pyrometry', as he preferred to call it. Since his death in 2013 the book has been completed by Dr David Lowe, a current practitioner at NPL. David Lowe gained a BSc in Physics at the University of Wales College of Car
