CERN's fellows and visitors get involved
From the July/August 1963 issue
Recent discussion of ways in which the smaller member states of the organization might obtain more benefit from their membership has included suggestions for increasing the opportunities available for fellows and other visitors who stay at Meyrin for relatively short periods. Out of some 260 physicists at present working directly on research in CERN, about 190 are fellows or visitors. Applied physicists, engineers and technicians add about another 80 to this last total.
The visits to CERN of young scientists from some countries - Poland and Japan are good examples - have already produced remarkable results in the development of interest in high-energy physics in their countries. The presence of visitors from Argentina, Australia, Brazil, Canada, Czechoslovakia, India, Israel, Japan, Lebanon, Pakistan, Poland, Romania, Syria, Turkey, the US, USSR and Yugoslavia - the list is not exhaustive - shows that at least in one activity the countries of the world can work together in harmony and to good purpose.
A grant from the Ford Foundation enables CERN to invite some 20 visitors each year from non-member states. There is also a growing number of visitors now coming to CERN with independent support, either on sabbatical leave, through the US National Science and Guggenheim Foundations or the International Atomic Energy Agency Fellowship programmes on various exchange programmes with, at present, Brookhaven (US), Dubna (USSR) and the Weizmann Institute (Israel), or simply paid for by their institutes.

Neutrino pre-run is a great success
The most exciting news during June was that after years of preparation and the last few months of intense activity to install the equipment for the most complex experiment ever to be attempted at CERN, the neutrino pre-run was a complete success. The proton synchrotron, the fast ejected beam system, the CERN heavy-liquid bubble chamber and the massive spark chamber array all worked smoothly, and everything pointed to the fact that CERN now possesses a new and outstanding tool for scientific research.
Nothing much can be said about the results yet, since this was only a preliminary experiment. However, the kind of particle tracks so far obtained, both in the bubble chamber and in the spark chamber, agree with last year's Brookhaven result that muon neutrinos and electron neutrinos are two different kinds of particle.
At this stage the programme is exploratory and […] the CERN experiments are designed to investigate in more detail the nature of the interactions both of neutrinos and antineutrinos (the latter coming from the decay of negative pions), and to search for the existence of a boson particle, thought by many to be involved in weak interactions in the same way as pions and kaons are involved in strong interactions.
