Development and Characterization of Thin Film Superconducting Radio Frequency Surfaces for Accelerator Cavities
Superconducting thin films have the potential to improve the performance of particle accelerators. Before these thin films can be implemented, a systematic study on structureproperty correlations is necessary. Here, we present the characterization of niobium thin films deposited onto both ceramic and metallic substrates. In particular, the film microstructure and superconducting properties are ...
متن کاملSurface Science Laboratory for Studying the Surfaces of Superconducting Radio Frequency Cavities*
A Surface Science Laboratory (SSL) has been established at JLab to study surfaces relevant to superconducting radio frequency (SRF) cavities. Current operational facilities include a scanning electron microscope equipped with energy dispersive x-ray analysis, a secondary ion mass spectrometry, a metallographic optical microscope, a transmission electron microscope, a high precision and large sc...
متن کاملSuperconducting cavities for accelerators
Superconducting cavities have been in operation in accelerators for 25 years. In the last decade many installations in storage rings and linacs have been completed. Meanwhile, nearly 1 km of active cavity length is in operation in accelerators. Large-scale applications of superconducting radiofrequency systems are planned for future e+e− linear colliders and proton linacs. Superconducting cavit...
متن کاملEvaluation of the Propensity of Niobium to Absorb Hydrogen During Fabrication of Superconducting Radio Frequency Cavities for Particle Accelerators
During the fabrication of niobium superconducting radio frequency (SRF) particle accelerator cavities procedures are used that chemically or mechanically remove the passivating surface film of niobium pentoxide (Nb2O5). Removal of this film will expose the underlying niobium metal and allow it to react with the processing environment. If these reactions produce hydrogen at sufficient concentrat...
متن کاملDesigning Superconducting Cavities for Accelerators
Rapid advances in the performance of superconducting cavities have made RF superconductivity a key technology for accelerators that fulfil a variety of physics needs: high energy particle physics, nuclear physics, neutron spallation sources, and free electron lasers. New applications are forthcoming for frontier high energy physics accelerators, radioactive beams for nuclear astrophysics, next ...
