EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH European Laboratory for Particle Physics Large Hadron Collider Project LHC Project Report ??? Fast Symplectic Map Tracking for the LHC
نویسنده
چکیده
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. A considerable speed-up is expected by replacing element-by-element tracking with the use of a symplectified one-turn map. We have applied this method to the realistic LHC lattice, version 6, and here report our results for various map orders, with special emphasis on precision and speed.

متن کاملEUROPEAN 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.

The Large Hadron Collider (LHC) will be the next particle accelerator built to serve the world's high-energy physics community at CERN, the European Organisation for Nuclear Research. Reusing the 26.7-km circumference tunnel and infrastructure of the existing LEP collider, the LHC will make use of advanced technology high-field superconducting magnets operated in superfluid helium to push the e...

A simple quasi-analytic model is developed for the dynamics of electron cloud generated by synchrotron radiation of the beam in the LHC beam pipe. The model allows to obtain a multipacting condition for the LHC parameters, takes into account the space charge effect and predicts an equilibrium density of the electrons. Based on this model, we find the electron lifetime and estimate the energy de...
