Abstract :
A method for measuring the response of a beam current monitor is described, and response and impedance measurement results for a Proton Storage Ring (PSR) wall current monitor are reported. The through-short-delay calibration method (TSD) is extended to measure the response of a current monitor embedded within hardware that interfaces to a network analyzer. Error correction parameters generated with the TSD-calibration are used to calculate the actual current present at the current monitor. The results show a marked increase in impedance due to the cables and combiners
