Manufacture, Assembly and Calibration of Rotating Coil Systems for Magnetic Measurements at CERN

CERN is the world’s biggest research centre for particle physics. Located in Geneva/Switzerland it has recently launched the first beam in its flagship project, the LHC (Large Hadron Collider), composed of thousands of superconducting and resistive magnets of different types.

Projects like LHC require a growing need of high precision magnetic measurement instrumentation and procedures. Measurement equipment, capable to qualify aspects like field strength, -errors, -angles and –axis at ambient and cryogenic temperature has been developed in the past. A major part of these measurements is done with rotating coil systems, all developed, assembled and calibrated at CERN. This talk gives an overview on how these instruments are built, qualified and used for different applications. Aspects like measurement precision and limits of these systems are mentioned as well as upcoming challenges for future accelerator projects.

As a public research organization CERN permanently seeks partners in industries for bi-directional technological exchange concerning magnetic measurement activities. We are open for collaborations in terms of know-how we can offer in high precision measurement techniques as well as we are looking for latest developments and products on the public market helping us to face future technological challenges in the field of magnetic measurements.
