Purpose Niobium sputtered on copper has been a popular alternative approach for superconducting radio frequency(SRF)community in the last few decades.Comparing to bulk materials of a few millimeters,high-purity niobium of merely a few microns is sufficient to realize superconductivity on the coated surface.Being niobium thin film,it has been widely acknowledged that surface quality of the substrate plays a vital role in obtaining a superior niobium coating with excellent SRF performance.Therefore,proper chemical treatment of the substrate before coating is crucial and the ultimate goal is to create a smooth and defect-free surface.Prior to the design of a cavity etching system,the mechanism of SUBU as well as two industry-used solutions is studied in detail on samples.Methods Copper samples were first pre-treated by mechanical grinding to remove fabrication damages,obvious defects and visible impurities.Two chemical solutions widely used in industries were subsequently chosen to etch the samples.Finally,the established SUBU solution was used independently on these pre-treated samples for comparison.Surface morphology and etching rate were measured accordingly.Results and conclusions Mirror-like copper surface was created by using the SUBU solution thus qualified for subsequent niobium sputtering,while the other two solutions used in industries were less effective with nonideal surface morphology.The chemical reactions,the experimental requisites and the involved processes are extensively elucidated for all three solutions.Limitations for SUBU were examined,and the optimum ratio of the chemical bath volume to sample surface area was also determined.These investigations will serve as an important guidance for the development of a chemical etching system for elliptical copper cavities. 展开更多

Purpose Surface quality of the substrate is widely acknowledged to be essential for the niobium thin film deposition. Mucheffort has thus been spent to improve the surface roughness by using various chemical etching techniques. However, surfacepreparation before the chemical etching also plays a part in obtaining a satisfactory substrate, but has rarely been studiedbefore. This paper aims to define a specification for the pre-polished copper substrate prior chemical etching and searches forsuitable alternative non-chemical grinding methods for the copper cavity.Methods Copper samples were mechanically pre-polished at first by using flap sanding wheels of different grits and thenchemically etched by using the well-established SUBU solutions. Surface roughness, as a figure of merit, was measuredand compared before and after SUBU. Optimum practice for pre-polishing may therefore be determined. The mechanicalgrinding was subsequently applied on the 1.3-GHz mono-cell copper cavity. Meantime, the previously reported centrifugalbarrel polishing method was also applied with new abrasive materials and modified schemes. A comprehensive study ofetching rate, surface roughness and morphologies was conducted.Results and conclusions The specification for surface roughness prior SUBU was determined. Due to a complex geometryand curved surfaces possessed by the 1.3-GHz copper cavity, the traditional mechanical grinding was proved to be not ideal.Satisfactory surface quality was obtained by using the alternative centrifugal barrel polishing on the cavity. The proposed newscheme and new abrasive materials were demonstrated to be effective, and a mirror-like surface was achieved on the coppercavity. The traditional mechanical grinding can therefore be replaced. This constitutes a dedicated study on pre-polishing ofthe 1.3-GHz copper cavity substrate prior chemical etching for niobium sputtering. 展开更多
