	B.S. Wang, K.-B. Liu NSRRC, Hsinchu, Taiwan
	This paper presents an implementation of a virtual instrument control interface and a digitally controlled interface card for Taiwan Light Source (TLS) corrector magnet power supplies (MPS). Eight pieces of corrector MPS converter module are monitored and controlled by the digitally controlled interface card with delimit boundary of ±10 voltage. The digitally controlled interface card was implemented with an ADS1278 24-bits multi-channel analog-to-digital converter、a DAC8718 16-bits multi-channel digital-to-analog converter and the TMS320F28335 digital signal processor. There are two control modes of the virtual instrument control interface, which are 1) local control mode by RS-232, 2) the remote control by MiiNePort\_E1 TCP/IP protocol; with the developed Labview control interface the user can choose which mode to communicate with the corrector magnet power supplies depending on the working environment.

WEPWO066	Frequency Control in the Cornell-ERL Main-Linac Cavity Production	cavity, niobium, target, controls	2453
	V.D. Shemelin, B. Bullock, P.R. Carriere, B. Clasby, R. Eichhorn, B. Elmore, J.J. Kaufman, J. Sears CLASSE, Ithaca, New York, USA
	Funding: NSF award DMR-0807731 Cavity fabrication can be broken down into three main stages: deep-drawing cups, welding the cups in pairs to obtain “dumbbells” and end groups, and, finally, welding the obtained components into a completed cavity. Frequency measurements and precise machining were implemented after the second stage. A custom RF fixture and data acquisition system were used for this purpose. The system comprised of a mechanical press with RF contacts, a network analyzer, a load cell and custom LabVIEW and MATLAB scripts. To extract the individual frequencies of the cups from these measurements, algorithm of calculations was developed. Corrections for the ambient environment were also incorporated into the measurement protocol. Two 7-cell 1.3 GHz cavities were produced with high field flatness immediately after fabrication.

WEPFI074	RF Cavity Spark Localization Using Acoustic Measurement	cavity, diagnostics, background, collider	2863
	P. Snopok IIT, Chicago, Illinois, USA A.D. Bross Fermilab, Batavia, USA P.G. Lane, Y. Torun Illinois Institute of Technology, Chicago, Illinois, USA
	Current designs for muon cooling channels require high-gradient RF cavities to be placed in solenoidal magnetic fields in order to contain muons with large transverse emittances. It has been found that doing so reduces the threshold at which RF cavity breakdown occurs. To aid the effort to study RF cavity breakdown in magnetic fields it would be helpful to have a diagnostic tool which can detect breakdown and localize the source of the breakdown inside the cavity. We report here on progress towards developing a diagnostic tool for detecting and localizing sparks in an RF cavity by using piezoelectric transducers.

	Generally the beam emittance can be measured by different Emittance Measurement Units (EMUs), such as the pepper-pot device, the slit-wire type facility and the Allison scanner. However, for a microsecond single-shot ion beam, the pepper-pot device is a suitable choice because of its cut-off single-shot technique without any time-consuming step. A pepper-pot based beam current & profile measurement device, which is a combination of Faraday cup technique and pepper-pot measurement facility, was developed at PKU. It consists of a main Faraday cup with a pepper-pot mask at its bottom, and a Faraday cup array locating 3 mm away from the pepper-pot mask. This device has been tested at the PKU LEBT test bench and the measurement results are consistent with the results acquired by the Allison scanner. By replacing the Faraday cup array with a fluorescent screen and a CCD camera, this device becomes a facility that not only has the ability to measure the total beam current and the beam profile, but also has the capability to measure the beam emittance for CW or pulsed ion beams. Details will be presented in this paper.

THPEA048	The FPGA-based Power Monitoring System for TPS Facility	monitoring, controls, factory, resonance	3252
	C.S. Chen, Z.-D. Tsai NSRRC, Hsinchu, Taiwan
	There are more and more non-linear electronic equipments such as inverters using in facility nowadays. These non-linear electronic equipments let us achieve energy saving, but induce other electrical pollution to the whole power grid in contrast. How to monitor the electrical noises from these non-linear equipments becomes an important issue. In this article, a set of power quality monitoring system based on FPGA and PAC has been built because of the programmability and fast processing speed. By using this monitoring system, any abnormality in power system and its spectrum will be recorded thoroughly. On the other hand, the maintainer could follow the trace of noise and then propose a suitable solution to eliminate the electrical interference too.

THPEA049	Implementation of the EPICS Data Archive System for the TPS Project	EPICS, controls, GUI, synchrotron	3255
	Y.-S. Cheng, Y.-T. Chang, J. Chen, P.C. Chiu, K.T. Hsu, C.H. Kuo, C.Y. Liao NSRRC, Hsinchu, Taiwan
	The EPICS framework was chosen as control system infrastructure for the new project of 3 GeV synchrotron light source (Taiwan Photon Source, TPS). Various control system prototypes of TPS with the EPICS mechanism have been gradually built and tested. One EPICS archive system is necessary to be developed to record various machine parameters and status information for long time logging. The archive system of CSS (Control System Studio) which named BEAUTY (Best Ever Archive Toolset, yet) was built to be used as the TPS data archive system in 3rd quarter of 2012. An archive engine takes PV data from EPICS IOCs via channel access, and stores them in the data storage. The PostgreSQL RDB (Relational Database) was adopted as the data storage for the BEAUTY. Both the historic PVs data and the archive engine configuration are saved into the same RDB. The archived data can be retrieved in a form of graphical representation using the CSS-based data browser. Taking the performance and redundancy into considerations, the storage servers and RDB table structures are tuned relatively. The efforts will be described at this report.
