Description
One of the planned slow extraction options for the SIS100 under construction at FAIR will be the excitation of a 3rd order resonance by means of the radio-frequency knock-out (RF KO) method. The system that is currently in its design phase will consist of two identical RF stations, each capable of providing a voltage amplitude of up to 5 kV between two electrodes (distance: 90 mm, length: 1.5 m) in the frequency range from 100 to 400 kHz.
This contribution presents the design of the overall system, highlighting the transformer topology with eight transformers per RF station that are connected in parallel on their primary side and in series on their secondary side. Each primary side will be driven by a semiconductor amplifier via a 230 m long coaxial line.
Investigations concerning the magnetic alloy (MA) based ring cores which form the inductance of the transformers and the effects of reflections along the transmission line between the amplifier and the transformer are shown as well as studies on the geometry of the exciter plates. The design presented here fulfills the competing requirements on amplitude, bandwidth, field homogeneity, cooling capacity, and space constraints.
