High Field Q-slope and Superconducting Radio Frequency Cavity Testing
High field Q-slope is a loss mechanism frequently encountered by superconducting radio frequency (SRF) cavities. The goal of this experiment was to identify correlations between cavity surface impurities, caused by either nitrogen gas or a thin layer of oxidized niobium, and high field Q-slope. Unfortunately, due to an unpredictable series of complications, cavity test results were not obtained...
متن کاملPrecision calibration of electromagnetic calorimeters with a radio-frequency quadrupole accelerator
Over the last six years, Caltech and AccSys Technology, Inc . have developed fast calibration techniques by using a pulsed proton beam from a radio-frequency quadrupole (RFQ) accelerator. The RFQ beam bombards a lithium (Li) or calcium fluoride (CaF2) target permanently installed in an experiment . Radiative capture of the proton yields a flux of single 17 .6 MeV photons from a Li target or sho...
متن کاملRadio Frequency Quadrupole Accelerator: A High Energy and High Current Implanter
In this chapter, issues of applying the radio frequency quadrupole (RFQ) accelerator to ion implantation for material modification and microelectronics will be discussed at first. Subsequently, several examples of the RFQ-based implanters will be introduced, with an emphasis on the ladder IH-RFQ accelerator at Peking University, of which the output beam energy spread is optimized to be much low...
متن کاملLow temperature laser scanning microscopy of a superconducting radio-frequency cavity.
An apparatus was developed to obtain, for the first time, 2D maps of the surface resistance of the inner surface of an operating superconducting radio-frequency niobium cavity by a low-temperature laser scanning microscopy technique. This allows identifying non-uniformities of the surface resistance with a spatial resolution of about 2.4 mm and surface resistance resolution of ~1 μΩ at 3.3 GHz....
متن کاملDevelopment 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 ...
