TI - Measurements and Calibration of the Stripline BPM for the ELI-NP facility with the Stretched Wire Method J2 - Proc. of International Beam Instrumentation Conference (IBIC2015), Melbourne, Australia, 13-17 September 2015 AB - A methodology has been developed to perform electrical characterization of the stripline BPMs for the future Gamma Beam System of ELI Nuclear Physics facility in Romania. Several prototype units are extensively benchmarked and the results are presented in this paper. The BPM sensitivity function is determined using a uniquely designed motorized test bench with a stretched wire to measure the BPM response map. Here, the BPM feedthroughs are connected to Libera Brilliance electronics and the wire is fed by continuous wave signal, while the two software-controlled motors provide horizontal and vertical motion of the BPM around the wire. The electrical offset is obtained using S-parameter measurements with a Network Analyzer (via the "Lambertso" method) and is referenced to the mechanical offset.
