Fast-Ramped Superconducting Magnets for FAIR Production Status and First Test Results

The SIS100 synchrotron for heavy ion research is based on fast-ramped superconducting magnets. These superferric magnets are being designed, built, and tested. The first 3-m-long series dipole (maximum field of 1.9 T; ramp rate of 4 T/s) has been built. We present the test results obtained (quench training, magnetic field, ac loss, and repetition rate) and compare them with the predicted values and the required operation parameters.

I. Introduction

THE Heavy Ion Synchrotron SIS100 is the core component of the FAIR Facility [1]; it has entered the construction phase with long lead items and major components being procured [2]. Further the main components of the new mass spectrometer Super Fragment Separator (Super-FRS) are being tendered [3], [4], which are in particular, the superconducting dipole magnets and the multiplet magnets. In total, roughly 500 superconducting magnets are required for SIS100 while approximately 180 magnets are needed for Super-FRS. This paper concentrates on the first results obtained on the SIS100 First of Series (FoS) dipole magnet.
