| Popis: | Beam position monitors (BPMs) are one of the very im-portant diagnostic components of any accelerator systemgiving information about beam position. It is a class of non-intercepting devices which use the coupling of the EM fieldaround a charged particle bunch to some sort of conductorelectrodes to recover beam position information from thebeam-induced signals. In this paper, a characterization studyof an in-house developed Button BPM including sensitivitymeasurement and transfer impedance studies is presented. Sensitivity measurement was done using the stretched wiremethod by passing current pulses through the wire of differ-ent diameters like 0.5 mm and 1 mm, thus mimicking thebehavior of the actual beam. Sensitivity information wasthen used to reciprocate the 2-D position map of the device. Owning to the time taken for such huge measurements, anautomated BPM test bench approach of the whole setup isdeveloped by remote interfacing over LAN. A substantialdecrease in measurement time was observed along with areduction in measurement error. Proceedings of the 9th International Beam Instrumentation Conference, IBIC2020, Santos, Brazil |
