Dr Alex Bainbridge (STFC Daresbury Laboratory)9/26/22, 9:50 AMMeasurement reportsVideo
Permanent magnets (PMs) are becoming an attractive proposition as an environmentally friendly and efficient replacement for electromagnets in modern particle accelerators. In recent years the Zero-Power Tuneable Optics (ZEPTO) collaboration between STFC and CERN has demonstrated that traditional limitations of PM technology, such as the ability to change the field in the magnet aperture, can...

The use of Fast Fourier Transforms (FFTs) to determine field harmonics in rotating coil measurements has been a fixture in the analysis of these measurements since first employed in the mid 1900’s. Instead, by solving matrix-based equations which effectively perform a Fourier Transform while simultaneously including time-based terms, advantages over the simple FFT can be realized and may offer...
