WAMSDO 2013 - Workshop on Accelerator Magnet, Superconductor, Design and Optimization - 15-16 January, Bldg. 6/2-024

→ Europe/Zurich
CERN

CERN
Description
Topic: The quench modelling, detection and protection of the individual superconducting magnets for LHC upgrades and future machines. The workshop is intended to support the ongoing collaborative design efforts of these magnets. The protection of the actual circuits in the machines is not part of this workshop in order to concentrate better on the early design efforts on these high field and/or large aperture magnets.
