EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH European Laboratory for Particle Physics THE LARGE HADRON COLLIDER, A MEGASCIENCE PROJECT

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...

EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH European Laboratory for Particle Physics METHODS AND RESULTS OF MODELING AND TRANSMISSION-LINE CALCULATIONS OF THE SUPERCONDUCTING DIPOLE CHAINS OF CERN'S LHC COLLIDER

Electrical modeling and simulation of the LHC magnet strings are being used to determine the key parameters that are needed for the design of the powering and energy extraction equipment. Poles and zeros of the Laplace expression approximating the Bode plot of the measured coil impedance are used to synthesize an R/L/C model of the magnet. Subsequently, this model is used to simulate the behavi...
