TUPIK105	The Design Improvement of Horizontal Stripline Kicker in TPS Storage Ring	1961
	P.J. Chou, C.K. Chan, C.-C. Chang, K.T. Hsu, K.H. Hu, C.K. Kuan, I.C. Sheng NSRRC, Hsinchu, Taiwan
	We plan to replace the existing horizontal stripline kicker of the transverse feedback system with an improved design. Large reflected power was observed at the downstream port of stripline kicker driven by the feedback amplifier. A rapid surge of vacuum pressure was observed when we tested the high current operation in TPS storage ring in April 2016. A burned feedthrough of the horizontal stripline kicker was discovered during a maintenance shutdown. The improved design is targeted to reduce the reflection of driving power from feedback system and to reduce beam induced RF heating. This major modification of the design is described. The results of RF simulation performed with the electromagnetic code GdfidL are reported as well.

WEPVA128	The Data Acquisition System and Inspection Equipment on Vibration Evaluation for Deionized and Cooling Water Pumps in TPS	3568
	Y.-H. Liu, Y.-C. Chung, C.K. Kuan, Z.-D. Tsai NSRRC, Hsinchu, Taiwan
	The purpose of this paper is to evaluate the vibration amplitude and spectrum for TPS water pump systems. The utility systems operate continuously since 2014, some of deionized and cooling water pumps produced higher vibration amplitude and noise during operation. The possibly reason could be poor system accuracy, inappropriate installation and commission adjustment. The data acquisition system on vibration evaluation for deionizes water pumps was established in 2016. Accord-ing to the long-tern vibration amplitude recording, the system operational status could be clarified. After vibra-tion test for several months, the bearing of booster deion-ized water pump was found abrasive since coupling be-tween motor and pump misaligned. Besides, the founda-tion of copper deionized water pump system was broken and observed by rapidly increase vibration amplitude in short term. The water pump systems were repaired and maintained base on vibration evaluation. There is still some remain problems for deionized and cooling water pump systems. The utility systems could prevent mal-function through regular vibration inspection and daily data acquisition.

WEPVA129	Arc-Flash Hazard and Protection for Electric Switchboard at NSRRC	3571
	T.-S. Ueng, Y.F. Chiu, C.K. Kuan, K.C. Kuo, Y.-C. Lin NSRRC, Hsinchu, Taiwan
	During the operation of electrical equipment the arc-flash accident could damage the equipment and endanger the working personnel. In order to prevent this type of accidents from happening and to minimize the damages, a delicate setup is being installed inside the electric switchboard for suppressing the accidents at the initial stage of arcing at NSRRC's power system. The installed device includes the arc sensor, the smoke detector, the high rupturing capacity fuse, the circuit breaker and the protection relay. Further improvement on preventing the arc-flash accidents is also under study.

	C.K. Kuan, C.K. Chan, Y.T. Cheng, J. -Y. Chuang, Y.M. Hsiao, I.C. Sheng, C. Shueh, H.Y. Yan NSRRC, Hsinchu, Taiwan
	The Taiwan Photon Source is a 3 GeV, 3rd generation synchrotron radiation source at the NSRRC. Phase-I commissioning includes seven Insertion Device (ID) Front Ends which are built to transmit intense synchro-tron radiation generated by In-vacuum Undulators and Elliptically Polarizing Undulators in the storage ring to the Photon Beamline. The total power and power distri-bution on Front End components is calculated and ana-lysed and Finite Element Analysis is used to verify the thermal performance under high heat loads while Monte-Carlo methods are utilized to simulate the vacuum pres-sure distribution. All apertures of the components are the same to simplify and standardize the design of the Front Ends. This paper describes main design considerations, especially the high heat load and vacuum pressure distri-bution.
