EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH European Laboratory for Particle Physics Large Hadron Collider Project LHC Project Report 16 Transverse Instabilities in the LHC

I first summarize the impedance model that I will be using (this is compiled from the work of several other authors). I then use the methods described elsewhere [1] to determine mode coupling thresholds and growth rates of multibunch modes, including the effects of multibunch mode coupling (see [1]). The effects of feedback are also considered.

EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH European Laboratory for Particle Physics Large Hadron Collider Project LHC Project Report ??? Fast Symplectic Map Tracking for the LHC

Tracking simulations remain the essential tool for evaluating how multipolar imperfections in ring magnets restrict the domain of stable phase-space motion. In the LHC, particles circulate at the injection energy, when multipole errors are most significant, for more than 10 million turns, but systematic tracking studies are limited to a small fraction of this total time—even on modern computers...
