چکیده

Button-type beam position monitors for SuperKEKB rings have been designed. The RF characteristics such as beam response, trapped modes or wake functions have been simulated using 3-D E-M codes such as GdfidL and HFSS. The estimated instability threshold from the trapped modes was much higher than the radiation damping time. The prototype units have been tested in the prototype-antechambers installed in KEKB rings. The mechanical reliability and the beam responses are also reported.

Beam Position Monitor System of DAΦNE

The DAΦNE beam position monitor (BPM) system consists of 150 monitors installed all along the machine. Design issues, calibration procedures, experimental results and performance of the system are described. The closed orbit in the main rings is extracted from the BPM signals through narrowband receivers (realized by Bergoz Precision Beam Instrumentation for DAΦNE), then acquired and processed ...

Beam Position Monitor System for the Orbit Feedback at the Interaction Region of Kekb

To maintain the optimum collision condition of the two rings, two special BPMs with 8-button electrodes, called OCTPOS, were installed inside the super-conducting quadrupole magnets (QCSs) at the interaction region (IR) of KEKB. Four normal BPMs with 4-button electrodes were incorporated outside the QCSs. We have commissioned the OCTPOS BPMs for simultaneous measurements of both the electron an...
