TI - Construction and Measurement of a Tuneable Permanent Magnet Quadrupole for Diamond Light Source J2 - Proc. of IPAC2022, Bangkok, Thailand, 12-17 June 2022 CY - Bangkok, Thailand T2 - International Particle Accelerator Conference T3 - 13 LA - english AB - Permanent magnets (PMs) are becoming an attractive proposition as a green and efficient replacement for electromagnets in particle accelerators. 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 flux density in the magnet aperture, can be overcome. Moving PM blocks relative to fixed steel structures that define the field, the strength may be changed while suitable field homogeneity is maintained. A new ZEPTO variant has been developed in conjunction with Diamond Light Source (DLS) to demonstrate the technology on a real accelerator. This magnet features a number of crucial design innovations over previous generations of ZEPTO magnets that improve the convenience and versatility of PM systems and demonstrate that they can be deployed in many situations. We present the construction and measurement results of this new magnet and outline the planned data collection whilst installed on DLS. We analyse its performance relative to design and discuss the new features with focus on the real-world implications of PM technology for current and future accelerators.
