In this paper the capacitance of the superconducting bus-bars applied in the cryogenic by-pass line for the SIS100 particle accelerator at FAIR is analysed. The unit capacitance of the bus-bars is calculated numerically and found experimentally. A 2D numerical model of a cross-section of the cable is applied. The capacitance is found with three methods. The stored energy, electric displacement field and charge gathered on the surfaces of the device are calculated and analysed. The obtained values are consistent. Experimental measurements are performed using the resonance method. The measuring system is undamped using a negative conductance converter. Small discrepancies are ob- served between numerical and experimental results. The obtained values are within the requirements of the accelerator design.}, type={Artykuły / Articles}, title={Analysis of capacitance of a cryogenic by-pass line for SIS100 particle accelerator at FAIR}, URL={http://www.czasopisma.pan.pl/Content/108841/PDF/art07.pdf}, doi={10.24425/aee.2018.124741}, keywords={line capacitance, superconducting bus-bars, particle accelerators}, }
