Description

In the storage ring of the Taiwan Photon Source (TPS), we have installed 172 Beam Position Monitors (BPMs) to continuously monitor the electron orbit. We have developed an automated monitoring tool that extracts BPM data from the database at scheduled intervals and calculates the standard deviation for each BPM over a specified period to quantify its stability. The system identifies the ten BPMs with the highest standard deviation and generates trajectory plots for the five most variable BPMs, highlighting the regions with the most significant electron beam position changes.

Additionally, the system integrates with the LINE Bot API to instantly transmit data charts to a LINE group, ensuring that relevant personnel receive information promptly. These charts provide critical insights, assisting personnel in quickly identifying potential BPM anomalies and addressing issues accordingly. This process enhances orbit stability and provides reliable technical support for the stable operation of the photon source.
