Parasitic signals in the receiving band of the Sub-Harmonic Arc Detection system on JET ICRF Antennas
2011 (English)In: AIP Conf. Proc., 2011, 17-20 p.Conference paper (Refereed)
When testing the SHAD system on JET ICRF antennas, parasitic signals in the detection band (5-20MHz) were detected. We have identified emission from grid breakdown events in the Neutral Beam injectors, and Ion Cyclotron Emission from the plasma. Spurious signals in the band 4-10 MHz are also often observed at the onset of ELM events. Such parasitic signals could complicate the design and operation of SHAD in ICRF systems for fusion devices. © 2011 American Institute of Physics.
