Abstract

The international FAIR project planned next to G.S.I. (Germany) will lead to the construction of two superconducting synchrotrons (SIS100 and SIS300). This article reports on the quench calculations and measurements performed on one short SIS100 dipole model (1.4 m), the first to be tested at the FAIR prototype test facility. Quench propagation velocities and time to reach the 0.2 V quench threshold were measured in the bus bars and compared to computed values. The hotspot temperature was measured for different Miits (integral of I² .dt) values at 6 and 8 kA and compared to temperatures computed with the Miits equation. This article also reports the use of one inductive spot heater.
