Title: The beam positions of the SPEAR storage ring

Abstract

The Stanford 2 GeV electron-positron storage ring is equipped with 20 beam position monitors. The principle of beam coupling is analysed and a calculation is made here for the sensitivity to beam current and position, as well as for the intrinsic distortion of this type of monitor. Beam orbit coordinates are reconstructed by scanning the monitor's four electrode signals and the 20 stations around the machine. Normalization of the data and electronics nonlinearity compensation are one of the routine tasks of the computer control system.

Commissioning results of the narrow-band beam position monitor system upgrade in the APS storage ring.

Conference Singh, O

When using a low emittance storage ring as a high brightness synchrotron radiation source, it is critical to maintain a very high degree of orbit stability, both for the short term and for the duration of an operational fill. A fill-to-fill reproducibility is an additional important requirement. Recent developments in orbit correction algorithms have provided tools that are capable of achieving a high degree of orbit stability. However, the performance of these feedback systems can be severely limited if there are errors in the beam position monitors (BPMs).

Beam position measurement in the photon factory storage ring

Conference Katsura, T ; Nakagawa, H ; Shibata, S - IEEE Trans. Nucl. Sci.; (United States)

A beam position monitoring system has been constructed for the 2.5 GeV electron storage ring in the Photon Factory. Since the first beam was stored at design energy on March 11, 1982, the position monitor system has been used for orbit measurements during routine operation and during machine studies. The authors confirmed that the accuracy and reproducibility of the system is within 0.2 mm.
Beam position monitor system for storage rings

Conference Nakamura, M ; Hinkson, J A

Beam position monitors (BPM) for synchrotron light storage rings usually consist of beam pickup electrodes, coaxial relays and a narrowband receiver. While accurate, these systems are slow and of limited use in the commissioning of an accelerator. A beam position monitor is described which is intended to be a principal diagnostic during debug and routine running of a storage ring. It is capable of measuring the position of a single bunch on the first or nth orbit to an accuracy of a few percent. Stored beam position is more accurately measured with averaging techniques. Beam position changes can be studiedmore »« less
