Synchronous Data Acquisition System for TPS and its Applications

Abstract

Orbit stability in 100 nm range is essential for a very small emittance synchrotron light source. However, all kinds of vibration sources such as cultural noise and technical noise might deleterious the orbit stability. A synchronous data acquisition system is necessary to study the connection between orbit motions and various related vibration sources. In this report, we present a synchronous data acquisition system, which integrates the vibration and the measurement of beam position, and then will be deployed in the Taiwan Photon Source (TPS). To test its applicability, systematic study of vibration using this system was performed at TPS before the beam commissioning, which is scheduled in the third quarter of 2014. Results will be summarized in this report.
