Description
The Hybrid Electromagnet-Permanent Magnet Tuneable Optics (HEPTO) magnet has been designed and built as part of the I.FAST collaboration as an energy saving alternative to traditional resistive electromagnets. The prototype magnet has been designed to meet the magnetic field requirements of the combined function dipole-quadrupole (DQ) magnets required for the Diamond-II upgrade. The prototype contains several design features for maintaining and tuning the field strength and quality, including a novel mechanical shimming method, trim coils and passive temperature compensation. We present here the results of the magnetic measurements of the built prototype magnet and demonstrate the ability to tune the field using the design features. We demonstrate that the nominal integrated field strength and homogeneity can be achieved with the permanent magnet solution, representing a 2.3 kW reduction in nominal power consumption compared to the equivalent electromagnet.
