Honouring Hans Bethe
Bethe has made important contributions to the fields of atomic, solid state and nuclear physics, and to the development of the theory of radiation. In 1967 he was awarded the Nobel Prize for calculations explaining how a star uses nuclear fuel as its power source, published in 1938. It is now known that most of the starlight visible in the night sky is produced by the ‘Bethe cycle’.
In the past 20 years his research has been devoted largely to explaining the structure of nuclei in terms of the forces acting among their constituents. He has also been interested in neutron stars, thought to be made up of matter closely packed at nuclear densities. He is now working on problems of nuclear physics as the Karl Compton Professor of Physics at the Massachusetts Institute of Technology.

Lots of protons
Since its summer shutdown ended on 1 August, the synchrotron at the Fermi National Accelerator Laboratory has been operating mainly at an energy of 400 GeV. Previously it was best described as a 300 GeV machine making occasional excursions to 400 GeV. It is now running just as efficiently at the higher energy, averaging some 100 hours of physics out of the 125 hours scheduled each week.
The intensity at 400 GeV has reached 1.72 × 1013 protons per pulse (compared with 1.75 × 1013 at 300 GeV). Most effort is now going towards achieving higher beam intensities. The high energies and high intensities bring additional problems in their wake but they are all under reasonable control.
With these quantities of protons pouring out of the machine, experimenters can be kept happy in all three experimental areas at once – Meson, Neutrino and Proton.

The COURIER 1976
New methods of production and distribution of the COURIER will be operated from the beginning of 1976. They result from discussions during the past year to see how the journal can better serve the high energy physics community. The guiding idea has been that the usefulness of the COURIER will be increased if it becomes more fully representative of the community at a time when the social and political climate makes integration of the whole field of research even more desirable.
We hope that after a few months of ‘running in’, we shall establish a better flow of news so that we can convey stories of what is happening in and around the field of high energy physics, no matter where these stories emerge.

On 13 November diplomats from the Chinese Mission in Geneva and Embassy in Berne were invited to visit CERN as a gesture of appreciation for their considerable help in organizing the visit of the CERN delegation to China in September. While their husbands busied themselves with things scientific and technical, the diplomats’ wives relaxed for a while, visiting the CERN Nursery School.

This archive feature will continue, with its backwards glance to yesteryears, albeit in a different format. If it provides a wistful touch of nostalgia for readers who were there then, for the majority who have come later it shows just how much things have changed – or maybe just how little in some cases!
