Brad Schoenrock Advisors Dave Meidlinger Matthias Liepe Testing SRF cavities Brad Schoenrock Advisors Dave Meidlinger Matthias Liepe

Preparing for testing Lab View Programs One utilizes a log power detector The other uses a quadrature modulator Measuring Qext for input coupler For cavity test we want Qext for the input coupler to be matched with Qo

Log Power Detector

Quadrature Modulator

Clean room testing Cleaned up cavity/stand to go into clean room Used a network analyzer to measure transmission & reflection coefficients to measure Qext

Qext data
