Title Uncertainty analysis of time constant measurements in SRF cavity testing
Contributors
Abstract At the start of superconducting radiofrequency cavity testing, cavity time constant measurements are taken and from these measurements the field probe external quality factor is calculated. This value is then used for the calculation of quality factor and accelerating gradient for the remainder of the testing process. In previous analyses the uncertainty of the time constant measurement has been given as 3%, but this is dependent on the measurement equipment and method used to estimate the time constant from the measured cavity decay curve. This paper presents an analysis of the uncertainty of the measurement equipment used in the Superconducting Radiofrequency Laboratory at STFC’s Daresbury Laboratory and a comparison of the different methods that can be used to estimate the time constant from a decay curve.
