| > > | Summary: Field emission is one of the main issues for quality factor degradation at high gradient operation. We propose to develop a detection system equipped with scintillating fiber in order to precisely detect field emission sources on the cavity surface. Currently, this is achieved by PIN diodes that require long installation time and cannot be mounted on cavities in their final configuration (with helium tank). The photon energy, produced by electrons impact on the cavity surface, can be estimated once the scintillating fibers are connected to a multi-channel analyzer. This will allow not only to detect the electron impact locations but also their energy, hence determine their origin more precisely respect to other detection systems. A detection system prototype will be designed and manufactured with different fibers (geometry and composition) and equipped with photomultiplier and multi-channel analyzer | |||||||
