Training Quench Performance and Quench Location of the Short Superconducting Dipole Models for the LHC

The short model program, started in October 1995 to study and validate design variants and assembly of the main Large Hadron Collider (LHC) dipoles, has achieved its last phase. The last models were focused on the validation of specific design choices to be implemented in the series production, and to the study of the training performance of the coil heads. This paper reports on the manufacturi...

Lhc Arc Dipole Status Report

The LHC, a 7 Tev proton collider presently under construction at CERN, requires 1232 superconducting (SC) dipole magnets, featuring a nominal field of 8.33 T inside a cold beam tube of 50 mm inner diameter and a magnetic length of 14.3 m. To achieve such high fields whilst retaining the wellproven fabrication methods of cables made with NbTi superconductors, it is necessary to operate the magne...

Energy Extraction for the Lhc Superconducting Circuits

The superconducting magnets of the LHC will be powered in about 1700 electrical circuits. The energy stored in circuits, up to 1.3 GJ, can potentially cause severe damage of magnets, bus bars and current leads. In order to protect the superconducting elements after a resistive transition, the energy is dissipated into a dump resistor installed in series with the magnet chain that is switched in...

The Superconducting Levitated Dipole Experiment (LDX)

The Levitated Dipole Experiment (LDX) explores the physics of high-temperature plasmas confined by a dipole magnetic field. Stable high-beta plasma has been created and confined by the magnetic field of a superconducting coil. Discharges containing trapped electrons form when microwaves cause strong perpendicular heating at cyclotron resonance. To eliminate the losses to the supports, the magne...
