Abstract

Techniques and results of RHIC BPM measurements are presented. These include wire scanner measurements of uncalibrated and calibrated BPM position and roll accuracy, preliminary measurements of the coupling between adjacent striplines to permit in situ offset calibration of the BPM signal cables and electronics, frequency dependence of the location of the BPM electrical center, and antenna measurements of the installed position of the electrical center relative to the cryostat fudicials. We also present results of simulations and measurements of cryogenic signal cable heating, and testing of the cryogenic feedthrus
