	Funding: Work supported by the U.S. Department of Energy. The Los Alamos Neutron Science Center (LANSCE) is replacing beam profile measurement systems, commonly known as Wire Scanners (WS’s). Using the principal of secondary electron emission, the WS measurement system moves a wire or fiber across an impinging particle beam, sampling a projected multi-bin distribution. Because existing WS actuators and electronic components are either no longer manufactured or home-built with antiquated parts, a new wire scanner beam profile measurement is being designed, fabricated, and tested. The goals for these new wire scanner include using off-the-shelf components while eliminating antiquated components, providing quick operation while allowing for easy maintainability, and tolerating external radioactivation. The WS measurement system consists of beam line actuators, a simple cable plant, an electronics processor chassis, and software located both in the electronics chassis (National Instruments LabVIEW) and in the Central Control Room (EPICS-based software). This WS measurement system will measure the more common H⁻ and H⁺ LANSCE-facility beams and will also measure less common beams. This paper describes these WS measurement systems.

WEPPC007	Image Processing for Characterization of Surfaces of Superconducting RF Cavities	cavity, superconductivity, linear-collider, collider	2218
	M. Wenskat, S. Aderhold, E. Elsen, S. Karstensen, F. Schlander, L. Steder DESY, Hamburg, Germany
	Funding: ILC HiGrade Optical inspection of finished Nb superconducting RF cavities has worldwide been established as an important tool for identification of field limiting surface features. Single defects in a single cell of a 9-cell cavity may severely constrain the maximum gradient while the micro-structure in the vicinity of a welding seam could affect the quench behavior. DESY has automated the imaging of critical cavity surface areas, in particular those of high magnetic field. With resolution of ~10 μm2 the information volume is large and the systematic examination becomes a necessity. The development of image processing algorithms has been started with two goals: automatic characterization of cavity surface properties and defect detection. The former results aid the quality assessment of cavities after manufacture; the latter serves to push the gradient performance. The status and prospects of the image processing for the European XFEL and ILC will be presented.

	Funding: Authored by Jefferson Science Associates, LLC under U.S. DOE Contract No. DE-AC05-06OR23177. CEBAF 12GeV upgrade project includes 80 new 7-cell cavities to form 10 cryomodules. Each cavity underwent RF qualification at 2 Kelvin using a high power accelerating gradient test and an HOM survey in JLab’s Vertical Testing Area (VTA) before cavity string assembly. In order to ensure consistently high quality data, updated cavity testing procedures and analysis were implemented and used by a group of 10 VTA operators. For high power tests, a cavity testing procedure was developed and used in conjunction with a LabVIEW program to collect the test data. Additionally while the cavity was at 2K, an HOM survey was performed using a network analyzer and a combination of Excel and Mathematica programs. Data analysis was standardized and an online logbook, Pansophy, was used for data storage and mining. The Pansophy system allowed test results to be easily summarized and searchable across all cavity tests. In this presentation, the CEBAF 12GeV upgrade cavity testing procedure, method for data analysis, and results reporting results will be discussed.

	A slow orbit feedback (SOFB) system has been developed to improve the orbit stability for the storage ring of the Siam Photon Source (SPS). The SOFB uses a PID controller method utilizing LabVIEW channel to access 20 BPMs and 28 correctors of the storage ring. The first phase implementation of the feedback loops based on this method was operated at 0.05Hz of sampling frequency, which reduce the fluctuation of both horizontal and vertical positions of the orbit from ~200 microns down to ~30 microns. The commissioning results indicate that further work and hardware upgrade are required. A higher sampling frequency at least 30Hz is strongly required for PID controller implementation. Upgrading of the existing 12-bit resolution corrector power supplies is also necessary. The basic principle of PID algorithms, hardware, software and commissioning results of the current SOBF system, as well as a future development plan, will be presented.

	Funding: Supported in part by SBIR Grant 4747 · 11SC06251 YBCO coated conductors are one of the primary options for generating the high magnetic fields needed for future high energy physics devices. Due to slow quench propagation, quench detection remains one of the primary limitations to YBCO magnets. Fiber optic sensing, based upon Rayleigh scattering, has the potential for quench detection with high spatial resolution. This paper discusses the potential of multicore CPU's and FPGA’s to accelerate the signal processing demands associated with Rayleigh scattering based quench detection systems in a real-time environment.

	B.S. Wang, J.C. Huang, K.-B. Lin NSRRC, Hsinchu, Taiwan
	The auto-tuning of PI-compensator for power converter is fulfilled by using the LabVIEW. The current error signals of the power converter with different PI compensating parameters are transferred by RS-232 or Ethernet communication interface from DSP card into LabVIEW and FFT analysis are calculated. The FFT analysis are stored in the batch file for further numerical analysis and the parameters with the best response is recognized which will be set as the default PI parameters. In addition, the feasibility and validity of auto-tuning theorem was verified by measuring the long-term stability of output current and during the long-term measuring period the stability and ripple current of the power converter are observed. In this thesis, the fully digital regulation controlled corrector magnet power converter with a shunt as the current sensing component was used as the developing platform. The auto-tuning theorem was realized and applied to the compensator of the power converter, and the best output current response of the power converter was fulfilled.

	To ensure the correct operation and prevent system failures, which can lead to equipment damage in the worst case, all critical systems in the Large Hadron Collider (LHC), have to be tested thoroughly during dedicated commissioning phases after each intervention. In view of the around 7,000 individual tests to be performed each year after a Christmas stop, a lot of effort was already put into the automation of these tests at the beginning of LHC hardware commissioning in 2005, to assure the dependable execution and analysis of these tests. To further increase the productivity during the commissioning campaigns and to enforce amore consistent workflow, the development of a dedicated testing framework was launched. This new framework is designed to schedule and track the automated tests for all systems of the LHC and will also be extendable, e.g., to beam commissioning tests. This is achieved by re-using different, already existing execution frameworks. In this paper, we outline the motivation for this new framework and the related improvements in the commissioning process. Further, we sketch its design and present first experience from the re-commissioning campaign in early 2012.

	Funding: ESS Bilbao Consortium Wired connections are very often irreplaceable in large scientific facilities due to performance and reliability issues. However, those communication links suffer from several disadvantages, such as lack of flexibility during deployment or reconfiguration and deterioration of wires and physical connectors. The goal of the present work is to introduce wireless EPICS sub-networks in a standard general wired EPICS system. This involves the study and selection of a proper wireless technology, architecture, communication strategy and security policy. To ensure the validity of the proposed approach, a thorough study of the results related parameters, such as throughput, security, repeatability and stability of the overall system is needed. Once those are considered, the next step is to decide where and when the replacement of physical connections with Wireless communication systems is suitable. The aim is to eliminate as many wires as possible without decreasing the reliability, security and performance of the current EPICS control network.
