	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.

THPOPT015	The Design of the Full Energy Beam Exploitation (FEBE) Beamline on CLARA	2594

	The CLARA facility at Daresbury Laboratory was orig-inally designed for the study of novel FEL physics utilis-ing high-quality electron bunches at up to 250 MeV/c. To maximise the exploitation of the accelerator complex, a dedicated full energy beam exploitation (FEBE) beam-line has been designed and is currently being installed in a separate vault on the CLARA accelerator. FEBE will allow the use of high charge (up to 250 pC), moderate energy (up to 250 MeV), electron bunches for a wide variety of accelerator applications critical to ongoing accelerator development in the UK and international communities. The facility consists of a shielded enclo-sure, accessible during beam running in CLARA, with two very large experimental chambers compatible with a wide range of experimental proposals. High-power laser beams (up to 100 TW) will be available for electron-beam interactions in the first chamber, and there are concrete plans for a wide variety of advanced diagnostics (includ-ing a high-field permanent magnet spectrometer and dielectric longitudinal streaker), essential for multiple experimental paradigms, in the second chamber. FEBE will be commissioned in 2024.

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.
