| Citation | Distinguished for his innovative role in the development of high precision detectors and their exploitation for physics. He suggested the possibility of searching for charm decays using the SLAC rapid cycling bubble chamber and initiated an imaginative scheme to provide the necessary trigger. These contributions were very important in the ultimate success of the experiment on the photoproduction of charm. Following a period at the e+e? collider at DESY, when he and his colleagues developed novel high precision detectors to study charm and beauty states, he led the Imperial College group into the large international collaboration [ALEPH] at CERN in 1984. He and his group developed a very precise tracking chamber to study heavy flavour physics. These data provide a very precise test of the Standard Model and Dornan's work was very influential in establishing its parameters. It was in recognition of his outstanding contributions to LEP physics, which has dominated Particle Physics in the 1990s, that he was selected in 1997 as spokesman of the whole collaboration responsible for all aspects of the experiment and in particular the physics. |
