Dr Frans Wijnen (Radboud University Nijmegen)


In 2007 the Nijmegen High Field Magnet Laboratory has embarked in a programme to design and construct a 45 T hybrid magnet to provide the highest magnetic field available to its user programme. We present the final design of the resistive insert coils for this hybrid, which will operate in the 12.3 T background field of the superconducting outsert magnet. The insert magnet has an outer diameter just shy of 600 mm and consists of five Florida Bitter coils, with the Nijmegen cooling hole optimisation. The coils will operate at 38 kA, with the innermost coils (A1 and A2) powered in parallel, and generate an on-axis field of 33.0 T. The power consumption is restricted to 21 MW to accommodate, if necessary, additional power to compensate for variations in Bitter disk thickness or deviations in cooling properties. Construction of the stamping tools for the disks has started and the first disks will be produced in the spring of 2018.
