CERN’s Large Hadron Collider boosts superconducting magnet performance

Magnetic field measurement instrument board achieves 100 times greater frequency bandwidth and resolution than previous design, contributing to ultra-high-precision beam-forming in world’s most powerful particle collider.

CERN photoThe European Organization for Nuclear Research (CERN) in Switzerland and the University of Sannio, Benevento, Italy, have collaborated on the design of an advanced instrument for measuring magnetic fields in CERN’s Large Hadron Collider (LHC) superconducting magnets. Called the Fast Digital Integrator (FDI) board, this measurement device uses Analog Devices’ A/D converters, analog 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 and 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 and other time dependent phenomena typical in high-field superconducting accelerator magnets that all negatively affect the quality of particle beams under study. The new FDI boards are used at CERN to measure magnetic flux at 10 revolutions per second through fast-rotating calibrated coils that evaluate the magnetic field produced by the LHC’s 8 Tesla accelerator magnets.

“Prior to the FDI board, the available electronic components were not suitable in terms of accuracy or resolution, which in the case of the Large Hadron Collider easily approaches 10 parts per million,” said Pasquale Arpaia, professor of engineering at the University of Sannio.  

The LHC is the world’s largest and highest-energy particle accelerator, as well as the biggest machine ever built by humans. Construction started in 2003, and the LHC was operational in 2008. Its mission is to probe some of the most fundamental questions of physics and advance the understanding of the most fundamental laws of nature.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
