Impedance Studies for VMTSA Module of LHC Equipped with RF Fingers

During the 2011 LHC run it was found that beam-induced heating causes many issues for accelerator components. Particularly some of the double-bellow modules, called VMTSA modules, were found to have deformed RF fingers and a broken spring, which had ensured good contact between them and a central in...

description During the 2011 LHC run it was found that beam-induced heating causes many issues for accelerator components. Particularly some of the double-bellow modules, called VMTSA modules, were found to have deformed RF fingers and a broken spring, which had ensured good contact between them and a central insert. Impedance studies have been performed for different types of nonconformities. It was found that even a small gap between the fingers and a central insert could be fatal for the VMTSA operation. Results of this study were an input for the further thermal analysis.
