At CERN on 6 October to open the 'Britain at CERN' trade exhibition, UK Under-Secretary for Trade and Industry Edward Leigh admires the CERN VIP visitors book with CERN Director for Technical Tasks Hans Hoffmann and Wendy Korda.

Mike Turner of /Chicago argued that excluding neutrino masses down 25 MeV is crucial since a tau neutrino mass in the 0.5 to 25 MeV region is forbidden in many theories. The 25 MeV mass upper limit is clearly within experimental reach in the near future. One highlight was the examination of the so-called 1-prong decay problem, where a few percent of these decays may be unaccounted for. There are two ways of looking at the data: one is to pick the most precise measurement of each decay mode and the other is to use the world average of all measurements. Using the former method and assum­ ing the most precise measurement is the best, there is no significant ment has rightly brought Picasso in­ problem.

This project was commissioned by the University of Bonn, designed and completely produced together with the University and installed at DESY Hamburg. All components were produced by the glass fibre compression process, the outer surfaces were copperplated and the components were bonded and machined so that they were ready to install.
