Abstract :
The wire technique has been implemented to measure the longitudinal coupling impedance of AGS (Alternating Gradient Synchrotron) Booster devices. The techniques are being refined to allow measurement of RHIC (relativistic heavy ion collider) devices at higher frequencies. All the measurements are performed using an HP8753 Network Analyzer controlled by GPIB (general-purpose interface bus) by a Macintosh computer. The computer provides an environment for automated data acquisition, data analysis, and report generation. Resistive matches between the 50- Omega analyzer cables and the 300- Omega pipe-and-wire structure allow the use of a simple response calibration in the measurement of S21 to 400 MHz. Results from ferrite-loaded RF cavities, position monitors, and kickers are presented.<>
