The SIS100 synchrotron utilizes fast ramped superconducting magnets operated with a frequency of 1 Hz. The beam pipe is of elliptic aperture and the dipole magnets are curved. Therefore, elliptic and toroidal multipoles were developed which allow describing the field concisely within the whole aperture. A mole (i.e., a measurement system based on a rotating coil probe with all auxiliary components operating within the magnet's field) was developed able to sustain ramp rates of up to 4 T/s. It was tested in the field of a conventional magnet and in the first SIS100 superconducting prototype magnet. We recall general design issues of the mole and describe their advantages. We present the first measurements of the mole on the SIS100 prototype and compare them to the results obtained with an independent system. We outline how the rotating coil probe measurements have to be interpreted in the curved magnet using toroidal multipoles, and possible further improvements of the system. Index Terms-Fast ramped superconducting magnets, field description, magnetic measurement.

Detection of inter-turn faults in transformer winding using the capacitor discharge method

et al. 2017

The paper presents results of an analysis of interturn fault effects on the voltage and current waveforms of a capacitor discharge through transformer windings. The research was conducted in the frame of the Facility of Antiproton and Ion Research project which goal is to build a new international accelerator facility that utilizes superconducting magnets. For the sake of electrical quality assurance of the superconducting magnet circuits, a measurement and diagnostic system is currently under development at Gdansk University of Technology (GUT). Appropriate measurements and simulations of the special transformer system were performed to verify the proposed diagnostic method. In order to take into account the nonlinearity and hysteresis of the magnetic yoke, a novel mathematical model of the transformer was developed. A special test bench was constructed to emulate the inter-turn faults within transformer windings.
