The European Spallation Source (ESS), currently under construction in Lund, Sweden, is a research center that will provide, by 2023, the world’s most powerful neutron source. The average power of the proton linac will be 5 MW. Pulsing this linac at

At large distances the electromagnetic field of a wire is the same as the field produced by a bunch. Such a long-range beam-beam wire compensator was proposed for the LHC, and single beam tests with wire compensators were successfully done in the SPS

An optimized design of the intersection region of LHC is presented. The starting point of the design is to move the quadrupole triplet to a minimum distance from the intersect 12 m. The innermost quadrupole must accommodate substantial heat load f

In 1996, the expected field errors in the dipoles and quadrupoles yielded a long-term dynamic aperture of some 8/spl sigma/ at injection. The target was set to 12/spl sigma/ to account for the limitations of our model (imperfections and dynamics). Fr

The dynamic aperture (D.A.) of the LHC is estimated by tracking a thin-lens model of the lattice over a real machine time of 9 seconds. This raw result is then processed to predict the D.A. over longer times and realistic conditions. We discuss the r

The multipolar content of the dipoles and quadrupoles is known to limit the stability of the beam dynamics in super-conducting machines like RHIC and even more in LHC. The low-beta quadrupoles are thus equipped with correcting coils up to the dodecap

A considerable amount of betatron coupling in RHIC was found to originate from the interaction region (IR) triplets. A series of dedicated beam studies was performed with the goal of measuring the coupling errors in the IR triplets. The studies used

To correct more efficiently the arc dispersion, the exact antisymmetry of the LHC optics is now broken, except in the low-/spl beta/ triplets common to the two rings. A new quadrupole is added between the experimental insertions and the dispersion su

Results from studies on transverse polarization in LEP over the past two years are presented. A single beam transverse polarization level of 57% at 45 GeV was reached adopting strategies to compensate depolarizing effects originating in the four expe

The renewed interest in polarized beams at the Z energy has stimulated a new round of studies. The asymptotic polarization degree, as calculated with the first‐order theory, now reaches 85%, with the help of new asymmetric wigglers and polarization
