A workshop at Argonne on high-gradient RF cavities attracted 90 participants, with contributions from CERN, KEK, SLAC, Argonne and Fermilab. Jim Norem reports.
Günther Plass looks back to the very beginnings of the Proton Synchrotron in the 1950s and its subsequent career as the centrepiece of CERN’s accelerator complex.
The Large Hadron Collider project has had to overcome challenges at every stage. Lyn Evans focuses on the three phases of approval, construction and operation.
By early December 2003 CERN had taken delivery of 154 superconducting dipole magnets – enough for the first octant of the LHC. This indicates that industrial production is now both on course and in full swing, as Lucio Rossi describes.
The reliability of the LHC will depend not only on the superconducting magnets but also on the interconnections between magnetic sections, as Blazej Skoczen explains.
Swapan Chattopadhyay reports on the recovery of Jefferson Lab’s superconducting linear accelerators in the wake of Hurricane Isabel last September.
Since its birth 25 years ago, the time projection chamber has developed into a mature technology that is used in many fields, as Spencer Klein describes.
Dyson and Rubakov share the Pomeranchuk Prize for 2003 Dyson and Rubakov Freeman Dyson, from the Institute for Advanced Study in Princeton, and Valery Rubakov, from the Institute for Nuclear Research (INR) in Moscow, have been awarded the […]
Marietta Blau Marietta Blau – Sterne der Zertrümmerung by Robert Rosner and Birgitte Strohmaier (eds), Böhlau Verlag. ISBN 3205770889, €29.90. Marietta Blau – Sterne der Zertrümmerung (stars of fragmentation) is the third in a new series devoted […]
From the August 1959 issue
g-2 measurement On 8 January the muon (g-2) collaboration, E821, which has been working for the past 15 years at the Brookhaven Alternating Gradient Synchrotron to measure the anomalous magnetic moment of the muon, released their final […]
Figure 1 Development work for the TESLA linear collider has recently made substantial progress. After a surface treatment called electrolytic polishing, four superconducting nine-cell niobium cavities reached accelerating gradients of more than 35 MV/m. This is the […]
The X(3872) A new and unusual particle – the X(3872) – has been discovered by the Belle collaboration at the High Energy Accelerator Research Organization, KEK, in Tsukuba, Japan, and confirmed by an entirely different experiment, the […]
ALSTOM Canada The largest piece of Canada’s $41.5 million (€32.5 million) contribution to the Large Hadron Collider (LHC) was completed in 2003 with the delivery of the last of 52 twin-aperture quadrupole magnets to CERN. These warm […]
Figure 1 A major milestone has been reached for the STAR detector at Brookhaven’s Relativistic Heavy Ion Collider (RHIC) with the hoisting of the upper half of the endcap electromagnetic calorimeter (EEMC) into place on the “west” […]
Three months into run 4 and the PEP II accelerator, the electron-positron collider at SLAC, is performing beautifully. Recent modifications of PEP II’s hardware and operations have allowed it to maintain more intense beams, and […]
Test assembly The first of a pair of steel tables and shielding superstructures, which will house the two 110 tonne forward hadron calorimeters for the CMS experiment at the Large Hadron Collider (LHC), are due at CERN […]
Ian Halliday The UK Particle Physics and Astronomy Research Council (PPARC) has outlined its latest research goals in its Strategic Plan for 2003-2008. Among its aims are to increase UK industrial competitiveness and gain leadership roles in […]
The International Committee for Future Accelerators (ICFA), chaired by director of SLAC Jonathan Dorfan, has announced the members of a 12-person International Technology Recommendation Panel (ITRP) for a future linear collider. The ITRP, with four […]
The US Department of Energy’s Office of Science has unveiled its 20 year science facility plan. This is in effect a roadmap for future scientific facilities to support the department’s basic science and research missions. […]
In hosting the recent RSIS conference, CERN took a bold step into the global policy arena. Manjit Dosanjh, John Ellis and Hans Hoffmann explain why.
