The Blackett Laboratory Department of Physics Review Faculty of Physical Sciences 2002 Introduction This has been a year of progress and achievement in the A number of major projects were initiated in the department, department. It continues to flourish and to be an exciting including a Basic Technology programme grant on the place to study and work. We continue to attract a large generation and application of attosecond light pulses and cohort of the cleverest young people into Physics, and to a DTI Beacon Award to Professor Paul French to develop give them a challenging education that they and the fluorescent lifetime image technology for biomedical external world value highly. We have not rested on our applications. The departmentÕs contribution to e-Science laurels: the degree programmes have undergone an and the GRID has continued to flourish. extensive revision this year and a new MSci programme in Theoretical Physics introduced. And its still a fun Members of the academic staff garnered a number of place to be! The undergraduate body has been very important awards and prizes during the year, reflecting successful in winning awards this past year: the Imperial the high standing they are held in by the outside world. College Physical Society won the Institute of Physics Professor Gareth Parry was elected as a fellow of the award for the best Physics Society in UK Universities. Royal Academy of Engineering. Professor Arkady Tseytlin Students in the department were very successful in the was awarded a Royal Society Wolfson Merit Award, a College Entrepreneurship Ideas Challenge, and a highly prestigious award intended to retain research stars in physics team won the top £25,000 prize. the UK.

The newly- Ellis Research Fellowship of the Royal Society to pursue her established Exploitation Committee, under Lesley CohenÕs work on quantum computing and quantum cryptography. leadership, is exploring ways in which the departmental Intellectual Property can be better used. To end on a sad note, I am sorry to say that Professor Tony Stradling died a few weeks after his retirement from A number of new staff joined us this year: we welcome the College. A memorial service was held to commemorate Professor Edward Hinds and Dr Ben Sauer who have his life and achievements in Oxford Cathedral, attended by joined the QOLS Group from the University of Sussex to many present and past members of the department who establish the Imperial College Centre for Cold Matter. Dr remember an outstanding colleague with great affection. Paul Nandra joined the Astrophysics Group from the Goddard Space Science Center in the USA. Dr Mark P. L. Knight FRS Neil and Dr Peter Torok joined the Photonics Group from Head of Department Oxford University. April 2003 The major refurbishment of research laboratories under the GovernmentÕs SRIF programme has delivered high quality space for new programmes. We have become used to having an army of contractors working in the place and this will continue for the coming year, but will result in laboratories more fitting for the 21st century. The cover: The images on the cover, which were obtained in December 2002, show the first ever measurement of the EarthÕs energy budget from a geostationary satellite, EuropeÕs first Meteosat Second Generation (MSG-1). The upper image is a measurement of the thermal energy emitted from the Earth and the lower image shows the amount of sunlight reflected by the clouds and the EarthÕs surface. The satellite is positioned over 0¡ latitude and 0¡ longitude, so that in the lower image we see Africa to the right, and South America to the left. These data were obtained by the Geostationary Earth Radiation Budget (GERB) instrument on MSG-1. GERB is a joint European project led scientifically by Imperial College London. Being in a geostationary orbit, GERB remains located over the Greenwich meridian and the Equator and is able to obtain images, like those shown here, every 15 minutes, which is much more frequently than has ever been possible before. These data are currently being used by researchers within Imperial College London and around the world to provide new insights into climate processes such as clouds and convective systems, and to improve the climate models used to investigate the future of the EarthÕs climate.
