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 […]

Applied research at CERN In the words of its Convention, CERN exists “for nuclear research of a pure scientific and fundamental character and in research essentially related thereto”. The applied research undertaken at CERN has […]

CERN Computing and Data Processing School School participants After the success of the Varenna School in 1970, a second CERN Computing and Data Processing School was organized from 10–23 September at Pertisau on the shore of the Achensee, […]

Pop physics Hadrons and kaons How to give insight into the concepts of particle physics? How to show the general public something of the inherent fascination and fundamental importance of a subject that seems so far removed from […]

CDC 7600 passes acceptance tests New computer-centre hall On 8 July, CERN’s new, large, central computer, a CDC 7600, passed its acceptance tests. This required 30 consecutive days of operation on CERN’s normal computing workload. Over those 30 days the computer was […]

Progress of telescope project ESO observatory The European Southern Observatory (ESO) is a joint enterprise of European astronomers to establish facilities beyond the reach of individual research centres. The aim is to study the sky in the […]

First pulses at 200 GeV “There it is” The National Accelerator Laboratory came into being in the summer of 1967 with the mandate to build and operate a 200 GeV proton synchrotron. The move to the site, around […]

CDC 7600 Since 1950, particle physics happened to be the most richly endowed domain of basic research. Secure in their ability to pay, high-energy physicists were not slow to recognize those features of their science which put […]

New home for apprentices Centre d’Apprentissage On 9 December, a ceremony was held to inaugurate the CERN “Centre d’Apprentissage”, with people from CERN’s Training and Education Section, the apprentices and their supervisors, and representatives of the Geneva authorities […]

Getting colder [Earlier this year] we reported the bringing into operation of a 45 cm3 polarized proton target working at 0.55 K. It now looks as if the development can be carried further with the testing of […]

Sodium gas ionization Collecting electrons The range of beam detectors at the ISR has been increased by the installation of a novel beam-profile detector, which observes the ionization caused in a sodium curtain through which the beam […]

Accelerator Conference The Eighth International Conference on High-Energy Accelerators was held at CERN from 20 to 24 September. It attracted about 200 specialists from many research centres, mainly in Europe, the US and USSR, in addition to […]

Heisenberg’s principles Heisenberg Remote from the noise and bustle of Europe’s capital cities, in the charming German lakeside town of Lindau close to the borders of Austria and Switzerland, Nobel prize winners in physics gathered from […]

Applications of accelerators There was a time, not long ago, when science and motherhood were beyond reproach. Today, both are under attack. Much of the basis for the attack on science is emotional, even irrational. […]

CERN heavyweights Gargamelle inauguration Gargamelle, the largest heavy liquid bubble chamber in the world, was inaugurated on 7 May when it passed formally from the charge of its designers and builders at Saclay to the charge of CERN. […]

The Medical Service Sample collection Since June 1965, the Medical Service has been responsible for surveying the health of the personnel and for sanitary control. The Staff Rules and Regulations and CERN Safety Codes define medical procedures, […]

The A2: split or not split? Whether the A2 meson has a split personality has been a source of controversy for the past five years. Missing mass experiments at CERN have indicated that the peak associated […]

First beams in the ISR Johnsen, Unser Commissioning storage rings is not so clear-cut as commissioning an accelerator, where the day when particles are accelerated to near design energy is fanfare day. For storage rings it is […]

Conference in Kiev The XVth International Conference on High Energy Physics was held in Kiev, the lively capital of the Soviet Ukraine, from 26 August to 4 September. This series of conferences, known as the Rochester Conferences, […]

Brookhaven AGS 10th anniversary Ω‐ particle 1964 The Brookhaven Alternating Gradient Synchrotron AGS really started in 1952. The Cosmotron had accelerated protons beyond 2 BeV (not yet called GeV) and although the machine was still too rickety to do […]

Preparing for a third ‘g-2’ Preparations are well advanced for a third experiment to measure the “g-2” of the muon [2 × the anomalous magnetic moment]. The second experiment improved the experimental accuracy of this […]

The 300 GeV project New proposals for the 300 GeV project were announced on 18 April. Here, we recap key headlines in its history. 1963 The European Committee for Future Accelerators (ECFA) urges the construction in Europe of […]

Mirabelle is ready to move Mirabelle, the large hydrogen bubble chamber built by the Elementary Particle Physics Department of the CEA, the French Atomic Energy Commission, is being dismantled for removal to Serpukhov’s 76 GeV accelerator, […]

Important experiment on the cheap On 5 December 1969 the University of Chicago-Berkeley neutrino neutral current experiment concluded its run at the 6 GeV Bevatron. The experimenters looked for the reaction K+→ π+ + ν + ν which, […]
