THP07	Long-term Stability Observed by Electron BPM and Photon BPM for Taiwan Photon Source	feedback, electron, photon, electronics	176
	P.C. Chiu, K.T. Hsu, K.H. Hu, C.H. Huang NSRRC, Hsinchu, Taiwan
	TPS is 3-GeV synchrotron light source which have opened for public users since September 2016 and now offers 400 mA top-up mode operation. The requirements of the long term orbit stability and orbit reproducibility after beam trip have been gradually more and more stringent and become a challenge from users’ request. Furthermore, the thermal effect would be expected to be worsen after 500 mA top-up operation which should deteriorate the orbit drift. The report investigates the long-term orbit stability observed from eBPM and XBPM and also evaluates the possibility of the local XBPM feedback.

THP16	Remote Waveform Access Supports with EPICS for TPS and TLS Control Systems	EPICS, controls, data-acquisition, Ethernet	198
	Y.-S. Cheng, K.T. Hsu, K.H. Hu, C.Y. Liao, C.Y. Wu NSRRC, Hsinchu, Taiwan
	To eliminate long distance cabling for improving signal quality, the remote waveform access supports have been developed and applied on the TPS (Taiwan Photon Source) and TLS (Taiwan Light Source) control systems. Waveforms include pulse magnets power supplies waveforms, AC waveforms of main power supplies, LLRF waveforms, beam signals, etc., and these are necessary to be monitored during routine beam operation. One is that use the EPICS-embedded data acquisition systems which are formed by the Zynq System-on-Chip architecture to capture the waveform signals; the other is that a dedicated EPICS IOC is used to communicate with the present Ethernet-based oscilloscopes to acquire each waveform data. According to specific purposes use, the different graphical applications have been developed and integrated into the existing operation interfaces. These are convenient to observe waveform status and to analyze the acquired data on the control consoles. The efforts are described at this paper.

THP20	Study of Energy Saving Operation for the TLS Booster Power Supply	power-supply, booster, operation, controls	210
	J. Chen, Y.-S. Cheng, K.T. Hsu, K.H. Hu, D. Lee, C.Y. Liao, C.Y. Wu NSRRC, Hsinchu, Taiwan
	Operating an injector of a synchrotron light source, energy efficiency is an important issue. Dipole and quadrupoles families of the booster synchrotron for Taiwan Light Source (TLS) is resonantly excited by three White circuits at 10 Hz rate. Magnet current cannot response in cycle-by-cycle basic due to resonance nature. The possibility of operation of the booster synchrotron in energy saving mode is explored. Minimizing the duration of magnet excitation without effect of the injected and extracted beam to support top-up operation for the TLS is investigated. Efforts will be presented in this report.

	ALBA, in collaboration with MAXIV, has developed a four-channel electrometer of 18bit deep with 8 ranges from 1mA to 100pA. The objective of accuracy in the measurements made clear from the beginning the need to compensate the components tolerances and its dependence with temperature. This paper describes the tests performed to characterize the acquisition chain, the automatic calibration developed and the hardware and software implemented to achieve the accuracy target.
