	To monitor the stability of photon beams, X-ray beam position monitors (BPMs) with quadrant PIN photodiodes or blades are installed in the beam lines and front ends. Although there are about 200 electron BPMs installed in the storage ring, the beam-line managers or users prefer X-ray BPMs to monitor beam stability. Among the beam lines, different electronics are used to acquire data at various sampling rates. A method to calculate the beam intensity fluctuation within different frequency ranges is described in this report. The results of calculations are shown in the control system and saved in the archive system thus helping to monitor and analyse beam quality on- and off-line. Initial experiences with this system will be discussed in this report.

	During TPS operation, the stability of beam size measurement with the synchrotron radiation interferometer (SRI) does not compare well with the older SRI at the TLS. Ground vibrations appear to transmit to the SRI optics. This paper describes how to reduce the effect of vibration and improve the system stability to improve the stability of the SRI beam size measurement dramatically. To enhance the SRI sensitivity, an intensity imbalance method is incorporated and its results are discussed.

	The Taiwan Photon Source (TPS) is available to users since March 2016. A beam trip diagnostic system is used as an important tool to analyze the cause of beam trip events since the beginning of 2017. The main function of the system is to record relevant signals when the stored beam is suddenly lost. In the past few months, some useful features have been added, such as capturing trigger signals for pulsers, power line voltage, and auto generated beam trip reports. A detailed system architecture, implementation and progress will be summarized in this report.
