	System on a chip (SoC) is widely used in embedded environment. Current generation SoC commercial products with small footprint and low-cost have powerful in CPU performance and rich interface solution to support many control applications. To deal with some embedded control applications, the "Banana Pi" which is a card-size single-board computer and runs Linux-based operation system has been adopted as the EPICS IOC to implement several applications. The efforts for implementing are summarized in this paper.

MOPGF087	TPS Booster Tune Measurement System	274
	P.C. Chiu, Y.-S. Cheng, K.T. Hsu, K.H. Hu, C.Y. Liao NSRRC, Hsinchu, Taiwan
	The TPS is a state-of-the-art synchrotron radiation facility featuring ultra-high photon brightness with extremely low emittance. Its Booster has 6 FODO cells which include 7 BD dipoles with 1.6 m long and 2 BH dipoles with 0.8 m long in each cell. After magnetization of stainless steel vacuum chamber of the booster were identified and then dismantled, annealed, and re-installed, the electron beam energy of the Taiwan Photon Source (TPS) in the booster ring has ramped to 3 GeV in a week. The booster tune correction during ramping is one of the main reasons why the booster commissioning progress is so fast. In this paper the summarized the booster tune monitor system will be summarised

MOPGF088	Integrating the Measuring System of Vibration and Beam Position Monitor to Study the Beam Stability	277
	C. H. Huang, Y.-S. Cheng, P.C. Chiu, K.T. Hsu, K.H. Hu, C.Y. Liao NSRRC, Hsinchu, Taiwan
	For a low emittance light source, beam orbit motion needs to be controlled within submicron for obtaining a high quality light. Magnets vibration especially quadruples will be one of the main sources to destroy the beam stability. In order to study the relationship between vibration and beam motion, it is highly desirable to use a synchronous data acquisition system which integrates measurement of vibration and beam position monitor systems especially for the coherence analysis. For a larger vibration such as earthquakes are also deleterious to beam stability or even make the beam trip due to the quench of superconducting RF cavity. A data acquisition system integrated with an earthquake detector is also quite necessary to show and archive the data on the control system. The data acquisition systems of vibration and earthquake measurement system are summarized in this report. The relationship between the beam motion and magnets vibration will also study here.

	The control system had been established for the new 3 GeV synchrotron light source (Taiwan Photon Source, TPS) which was successful to commission at December 2014. Various control system platforms with the EPICS framework had been implemented and commissioned. The relational database (RDB) has been set up for some of the TPS control system applications used. The EPICS data archive systems are necessary to be built to record various machine parameters and status information into the RDB for long time logging. The specific applications have been developed to analyze the archived data which retrieved from the RDB. One EPICS alarm system is necessary to be set up to monitor sub-system status and record detail information into the RDB if the problem happened. Some Web-based applications with RDB have been gradually created to show the TPS machine status related information. The efforts are described at this paper.
