The Department of Medical Physics and Bioengineering is a joint department of University College London (UCL) and the UCL Hospitals Trust . The academic and research work of the Department is concentrated primarily within Shropshire House (shown opposite), a short distance from the main UCL campus. It also has laboratories on three other nearby sites: University College Hospital, Middlesex Hospital, and Whittington Hospital. Visitors requiring directions how to locate Shropshire House should click here The spectrum of Medical Physics activities undertaken in this Department is probably the broadest of any in the United Kingdom. Roughly one half of the 130 members of staff are employed by the UCL Hospitals to provide medical physics service. The rest are principally involved in the pursuit of academic research, including industrial contract research, and teaching activities associated with the graduate and post-graduate degrees offered by the Department.

124. Steven Chu, Former Bell Labs Researcher, Wins Nobel In Physics Using lasers to trap and cool molecules for study. Nobel Prize for Chu, Phillips, and CohenTannoudji. http://www.bell-labs.com/user/feature/archives/chu/

Former Bell Labs Scientist Steven Chu Wins Nobel Prize The idea of using lasers to trap and cool molecules for study began over a lunchtable conversation at Bell Labs in Holmdel, N.J. more than 10 years ago. Today, because of his idea, former Bell Labs researcher Steven Chu is one Nobel Prize in Physics richer. Holmdel, N.J (October, 1997) An idea that sprang up over lunch at a Bell Labs cafeteria a little more than a decade ago has led Steven Chu to the most coveted honor in science. On Oct. 15, the 1997 Nobel Prize in Physics was awarded to Chu, now at Stanford University, and two others, William Phillips and Claude Cohen-Tannoudji, for their development of methods to cool and trap atoms with laser light. Steven Chu The research that drew the attention of the Royal Swedish Academy of Sciences began at Bell Labs in Holmdel. A dozen years ago, Arthur Ashkin and Chu used to discuss physics regularly at the Holmdel cafeteria. They were interested in manipulating atoms at low temperatures. An idea that arose during one of those lunches led to a series of experiments by Chu, Ashkin, John Bjorkholm, Alex Cable, and Leo Holberg. Chu left Bell Labs in 1987 to take up a professorship at Stanford, where he continued his work in low-temperature physics. Ashkin Pioneered "Optical Trapping"

Like many things in physics, refractive index isn't as simple as we learned in high school. In addition to the familiar constant is a term that depends on intensity: n n n I This intensity dependence, known as the optical Kerr effect, underlies the phenomenon of self-focusing. If a beam of light is brighter in the center than at the edgesas most arethe center will encounter a bigger refractive index and slow down. Wavefronts that start out planar will therefore collapse about the center. A tighter beam results. For air
