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...
متن کاملQuench simulations for superconducting elements in the LHC accelerator
The design of the protection system for the superconducting elements in an accelerator such as the Large Hadron Collider (LHC), now under construction at CERN, requires a detailed understanding of the thermo-hydraulic and electrodynamic processes during a quench. A numerical program (SPQR Simulation Program for Quench Research) has been developed to evaluate temperature and voltage distribution...
متن کاملMeasurements of Magnetic Field Pattern in a Short LHC Dipole Model
The magnetic field in superconducting accelerator magnets has a fine structure with longitudinal periodicity. This periodic pattern, with period identical to the cable twist pitch, is originated by uneven current distribution within the cable. Here we present results of measurements of the periodic pattern performed in an LHC dipole model. We report in particular the results obtained powering t...
متن کاملField-shape Variation Induced by Thermal Cycling and Excitation in the Lhc Dipole
The field-shape imperfections measured at room temperature before and after thermal cycling and excitation up to maximum field in three 10 m-long models of the LHC dipole are presented. A systematic variation is observed in the normal sextupole and decapole components. The variation of the other components turns out to be negligible or to randomly vary (as for normal and skew quadrupoles). We s...
متن کاملObservation of magnetic flux generated spontaneously during a rapid quench of superconducting films.
We report observations of spontaneous formation of magnetic flux lines during a rapid quench of YBa(2)Cu(3)O(7-delta) films through T(c). This effect is predicted according to the Kibble-Zurek mechanism of creation of topological defects of the order parameter during a symmetry-breaking phase transition. Our previous experiment, at a quench rate of 20 K/s, gave null results. In the present expe...
