Honouring Hans Bethe Physicists and friends from all over the USA assembled at Cornell University on 24 October to honour Hans Bethe on his retirement. Bethe has made important contributions to the fields of atomic, solid […]

Storing data on videotape One of the problems in high-energy physics experiments is the handling and storage of large volumes of data. It is not unusual for an experiment to need a thousand magnetic tapes. […]

Further contacts with China In the summer of 1973 a delegation of physicists from the People’s Republic of China, headed by Professor Chang Wen-Yu, made an extensive tour of high-energy physics laboratories in the USA, […]

Around CERN Versatile transporter The versatile transporter which was used to convey the precisely assembled and measured magnets of the Intersecting Storage Rings to their positions in the tunnel. Vehicles of this type are now […]

Extended collaboration with Soviet scientists On 10 July a Protocol was signed by Director General W K Jentschke, representing CERN, and Deputy Chairman I G Morozov, representing the USSR State Committee for the Utilization of […]

A post-Frascati review A coil of superconducting magnet The Fifth International Conference on Magnet Technology was held from 21–25 April in Rome, having relocated from the Frascati Laboratory because of increasing attendance. Interest focused on the use of superconducting magnets in […]

TRIUMF triumph Celebration On 15 December the 500 MeV cyclotron at Vancouver produced its first full energy beams. After a month of gradually spiralling the beam further and further out in the machine, success came precipitately. On 14 December […]

The new particles Sam Ting 1974 has been one of the most fascinating years ever experienced in high-energy physics. Anyone in touch will be well aware of the ferment created by the recent news from Brookhaven and […]

Final touches Synchro-cyclotron has protons again On 1 October the refurbished CERN synchro-cyclotron (now known as SC2) accelerated protons to the full energy of 600 MeV in a very successful start to its recommissioning. The SC was the […]

Stanford Accelerator Conference The sessions on superconductivity at the IXth International Conference on High Energy Accelerators, held at the Stanford Linear Accelerator Centre from 2–7 May, were somehow rather frustrating. For many years, the potential […]

Bubble-chamber picture Our changing view of the nature of matter 1954–1974 The electromagnetic force In quantum electrodynamics (QED) intermediary photons removed the enigma of “action at a distance” between charged particles. However, when trying to calculate physical […]

All the world’s a hadron Detection system Following the coming into operation of the 6 GeV Bevatron at Berkeley in February 1954, the particle population explosion defied understanding. Then came a beautiful application of unitary symmetry theory, which […]

Computers Stock of tapes After a running-in period which was expected to last about a year, the new central computer, the CDC 7600, can now handle more work than all the other computers at CERN put together. A sector […]

CERN: a source of European spirit Auger, Bohr If we look at mid-1945 Europe, a continent broken up as it emerged from World War II, in the minds of political leaders and diplomats the restoration of Europe’s place […]

Scanning tables at CERN MILADY scanning tables Photographs of tracks made by high-energy charged particles passing through a bubble chamber constitute one of our most direct means to access the sub-nuclear world. No other detection technique gives such […]

European Molecular Biology Laboratory Speaking at CERN An agreement was signed at CERN on 10 May setting up a new European laboratory for research in molecular biology. Located at Heidelberg in the Federal Republic of Germany, it will be […]

BEBC getting ready to operate BEBC control room First tracks were taken in the 3.7 m Big European Bubble Chamber (BEBC) in March. A hydrogen leak that interrupted the tests was repaired quickly and operation continued up to 2.6 T. […]

Telling the mole in the hole where to go Mole installation February 19 was the second anniversary of the authorisation of construction of the Super Proton Synchrotron (SPS). It was celebrated by the start of tunnel boring […]

News from Gargamelle Antineutrino interaction Having obtained evidence for new hadronic constituents [partons] by electromagnetic and strongly interacting probes, the question arises whether they also manifest themselves in weak interactions. Preliminary measurements of the total cross-sections for […]

Two years on Tunnelling machine Almost two years ago, CERN Council approved the “Programme for the Construction and Bringing into Operation of the CERN 300 GeV Laboratory”. The SPS [Super Proton Synchrotron] project has now reached the stage […]
