چکیده
For the stable high-luminosity operation and luminosity-increase, the electron and positron storage rings of the KEK B-Factory (KEKB) is equipped with various beam instrumentations, which have being working well since the start of the commissioning in December, 1998. Details and performance of the beam-position monitor system based on the spectrum analysis using DSPs, the turn by turn BPM with four dimensional function available for measurements of the individual bunch position, phase and intensity, the parametric beam-DCCTs designed so as to avoid the magnetic-core-selection problems for the parametric flux-modulation, the bunch by bunch feedback system indispensable to suppress the strong multibunch instabilities in KEKB, the various optical beam diagnostic systems, such as synchrotron radiation interferometers for precise beam size measurement, the tune meters, the bunch length monitors and the beam-loss monitors are described. Delicate machine tuning of KEKB is strongly supported by these instrumentaions.

Overview of Beam Instrumentation for High-intensity Storage Rings
This paper will present an overview of beam instrumentation with a view towards relevance for future accelerator projects on the basis of experience at KEKB. The KEKB B-Factory shares with other existing and planned electron and positron machines the requirement for precise measurements at high beam intensities.
متن کاملCommissioning Status of the Kekb Linac
After entering into the full-commissioning phase of the KEKB linac in May, 1998, we have established two linac injection modes for the KEKB ring: an 8-GeV electron beam and a 3.5-GeV positron beam, as well as beam modes for the rings of the synchrotron light sources. All modes are easily switched for almost one minute without any trouble. The linac beam characteristics have been substantially i...
متن کاملBeam Diagnostics Using Bunch-by-bunch Feedback Systems in the Kekb Rings
Transverse bunch-by-bunch feedback systems for damping coupled-bunch instabilities in the KEKB rings have been working well since the early stages of the commissioning of the rings. Beam diagnostic systems that are the part of the bunch feedback systems, such as bunch current monitors, betatron-tune measurements systems, and bunch oscillation recorders, have been playing important roles in the ...
متن کاملRecalibration of a Wall-current Monitor Using a Faraday Cup for the Kekb Injector Linac
An absolute beam-charge measurement of single-bunch electron beams with a pulse width of 10 ps and shortpulsed electron beams with a pulse width of 1 ns was performed by the beam test for the KEKB injector linac using a Faraday cup. A wall-current monitor was directly recalibrated by the beam test with an error of ±2%.
متن کاملPlc-based Beam Charge Interlock System for Radiation Safety in the Kekb Injector Linac
A new PLC-based beam charge interlock system is under development for radiation safety and machine protection in the KEKB injector linac. This system restricts integrated amounts of beam charges passing through several locations along the linac before they are injected into four different storage rings (KEKB ee storage rings, PF, PF-AR). The beam charges are measured using wall current monitors...
