Analog Devices' Signal Processing Technology helps CERN's LHC achieve highest Superconducting Magnet Performance

摘要

The European Organization for Nuclear Research (CERN) in Switzerland and the University of Sannio, Benevento, Italy, collaborated on the design of an advanced instrument for measuring magnetic fields in CERN's Large Hadron Collider (LHC) superconducting magnets. This measurement device uses Analog Devices' A/D converters,rnanalog multiplexers and DSP components to provide the LHC with the highest possible performance achieved to-date in measuring magnetic fields. The new FDI board enables 100 times the resolution & frequency bandwidth of the previous generation digital integrator. This significant improvement in dynamic range enables scientists to detect even more minute artifacts that contribute to magnetic field variations, field decay & other time dependent phenomena typical in high-field superconducting accelerator magnets, negatively affect the quality of particle beams under study.
