The Large Hadron Collider (LHC) in the LEP tunnel

After the remarkable start-up of LEP, the installation of a Large Hadron Collider, LHC, in the LEP tunnel will open a new era for the High Energy Physics. This report summarizes the main LHC parameters and subsytems and describes the more recent studies and developments.

The muon (g-2) precession experiments: past, present and future

Abstract In this review we survey the various experiments completed or in preparation, which are designed to probe the anomalous magnetic moment of the muon to greater and greater precision. The emphasis lies particularly on the general issues involved and also on the most recent developments.

The CERN muon (g-2) experiments

Abstract In this review we trace the evolution of the three muon ( g -2) experiments which have played a considerable role in the history of CERN. In doing so, our discussion of the measurements is by no means comprehensive since full reports have already been published elsewhere. Instead we have endeavoured to place each in its physics context and to point out the technical developments that were necessary to achieve the succeding steps in precision.

Separated high-energy electron beams using synchrotron radiation

Abstract Electrons with kinetic energy in the 100 GeV range may be separated from other particles by using their energy-loss due to synchrotron radiation in a high-field magnet. In this paper the associated fluctuations in energy and angle are shown to be small enough for the method to be useful. Detailed design formulae are presented for several magnet configurations.

The Muon (g — 2) Experiments at CERN

In this lecture I shall discuss measurements of the dipole moments of free electrons and muons, and the lifetime of free muons. I shall discuss these experiments in terms of physical principle rather than technical details; full accounts of the experimental methods may be found in the original papers to which reference is made in some of the review articles given below1).

Francesco Ruggiero 1957-2007

Francesco Ruggiero (1957-2007) was a brilliant acceler- ator physicist, an inventive researcher, a great collaborator, an excellent mentor, and a true gentleman. We here take a look at Francescos scientific work, and highlight some of his contributions to accelerator physics. More details can be found in the slides presented by the speakers of the Francesco Ruggiero Memorial Symposium held at CERN on 3 October 2007 (2).
