Trieste workshop puts a RICH variety on show
Ring imaging Cherenkov (RICH) counters provide a unique tool to identify charged particles by measuring their velocity, even when it differs from the velocity of light by only one part in 10 million....
Solving the mystery of the missing neutrinos
The end of an era came on 28 November 2006 when the Sudbury Neutrino Observatory (SNO) stopped data-taking after eight years of exciting discoveries. During this time the observatory saw evidence tha...
PET and CT: a perfect fit
David Townsend is a professor in the Department of Medicine, University of Tennessee Medical Center in Knoxville, Tennessee (TN). The winner of the 2004 Clinical Scientist of the Year Award from the A...
Needles in high-speed haystacks
The new generation of big proton–proton colliders now being planned in Europe and the US aims to open up the collision physics of the constituent quarks and gluons hidden deep inside the proton. Loc...
Detector trends by Georges Charpak
Every year sees the emergence of new breeds of detectors and the improvement of existing ones, but the innovations which go on to make a significant impact on physics research are limited. The large i...
ALEPH
Our previous issue carried the first of a series of articles (DELPHI, page 27) on the four major experiments for CERN’s 9 kilometre diameter LEP electron–positron ring, now under construction an...
Gargamelle: CERN’s new heavy liquid bubble chamber
In the April issue of CERN COURIER we reproduced a photograph of the arrival of the first piece of the new heavy liquid bubble chamber ‘Gargamelle’. The 140 ton base-plate for the magnet was towe...
Nuclear emulsions
The possibility of detecting individual charged particles by means of a photographic emulsion was first investigated as long ago as 1910 by Kinoshita, working at Manchester University. He was continui...
