	The Taiwan Photon Source (TPS) is a 3-GeV third-generation source of synchrotron radiation with beam current 500 mA stored in the storage ring. A front end allows intense synchrotron light generated in the storage ring to pass through to a beamline. Most heat load of the synchrotron light is removed in the front ends to protect the beamline components. Alignment of front-end components becomes important to prevent damage from the large heat load. Because of the many front ends and the brief period of installation, the alignment work should be easy, quick and reliable. Using a shim method, the adjustable degrees of freedom are decreased from six to two. This adjustment work becomes easier and quicker. The alignment of a front-end prototype is described here.

	In this paper, the survey status at NSRRC site duirng the TPS (Taiwan Photon Source) civil construction is described. The TLS (Taiwan Light Source) ring is still under operation in the meantime. In order to maintain the TLS for normal operation and also monitoring the building construction, an expanded survey setups including permanent leveling and GPS monuments were installed both on the site and TPS building. Combined with the orignal TLS survey sockets and sensor monitoring system (hydrostatic leveling system and precision inclination sensors) installed both in the TLS storage ring and beamlines, an extensive survey tasks were performed. The ground deformation situation of the TLS and deviation of the TPS building construction are presented.

MOPO034	From Survey Alignment toward Auto-alignment for the Installation of the TPS Storage Ring Girder System	laser, alignment, photon, controls	559

	The TPS (Taiwan Photon Source) project is now under civil construction. The whole building is constructed half underground and 12m deep compared to the TLS due to the stability consideration, so the survey and alignment works are quite confined and difficult. For positioning the magnets precisely and quickly, a high accuracy auto-tuning girders system combined with survey network procedures were established to accomplish the installation tasks. The position data from the survey network will define a basis for the motorized girder system to auto-tune and improve the accuracy. A mockup of one twenty-fourth section (one cell) had been installed at NSRRC for interface examination and further testing. In this paper, the procedures from the traditional survey network to auto-aliment system design and algorithm are described. Meanwhile, a preliminary testing result is also included.

TUPO014	High-flux Gamma-ray Generation by Laser Compton Scattering in the SAGA-LS Storage Ring	laser, photon, storage-ring, electron	1476
	T. Kaneyasu, Y. Iwasaki, S. Koda, Y. Takabayashi SAGA, Tosu, Japan
	We constructed an experimental setup for high-flux gamma-ray generation by laser Compton scattering (LCS) in the SAGA-LS storage ring. The SAGA-LS is a synchrotron radiation (SR) facility consisting of a 255 MeV injector linac and a 1.4 GeV storage ring. We employed a CO2 laser having a wavelength of 10.6 micrometer to produce gamma-rays in the few MeV region in conjunction with the SR user time. The LCS gamma-ray up to the maximum energy of 3.5 MeV is generated via head-on collision between the laser photons and the 1.4 GeV stored beam. Since the energy acceptance of the storage ring is well above the maximum gamma-ray energy, the LCS experiment can be performed without reducing the beam lifetime. As a first step for high-flux gamma-ray generation, we use a small 10 W CO2 laser for beam test. The LCS event rate is designed to be 2·10⁸ ph/s with a beam current of 300 mA and a laser power of 10 W. A further increase of the LCS event rate in the order of 10¹0 ph/s is expected when a kW class laser is utilized. We report on the characteristics of the LCS gamma-rays observed in the low current beam test and an experimental result for evaluating the gamma-ray flux at a current of 300 mA.

TUPS003	Upgrade of the ESRF RGA System	vacuum, controls, diagnostics, monitoring	1521
	A. Meunier, M. Hahn, I. Parat, J.L. Pons ESRF, Grenoble, France
	In the frame of the ESRF upgrade program, the Residual Gas Analyzer (RGA) system has been reviewed. A campaign of RGA refurbishment has been started recently giving more reliability and accuracy on partial pressure vacuum control. Based on new technologies and our operating experience, new RGA monitoring application and diagnostic tools have been developed. This paper outlines the evolution of the actual RGA system focusing on the controlled hardware installation description, on software and user interface developments. The continuous follow up of a defined number of partial pressure measurements using different dynamic control modes will be described.

	Accelerators, beam lines, and experimental halls located in the J-PARC site were displaced by the 2011 off the Pacific coast of Tohoku Earthquake happened on 11th March, whose magnitude was nine, and its following many aftershocks. Site-wide network of measurement points distributed on grounds, buildings, and magnets was surveyed by using GPS survey system, precise digital levels, and laser trackers. The effect from the megaquake was reported for each J-PARC components, such as LINAC, Rapid Cycling Synchrotron (RCS), Main Ring (MR), neutrino and hadron beam lines, and experimental halls.

	Funding: CERN, Geneva, Switzerland EBG MedAustron, Wiener Neustadt, Austria "Give me a layout good enough and a building to place it, and I will install your accelerator". To paraphrase Archimedes, this is the role attributed to Integration team in MedAustron project. Starting with the optics layout and a building sketch, the integration work consists of a series of activities, interlinked in a complex manner. First the design and integration of the accelerator: list items, define geometrical envelopes with interfaces, put them in position in CAD, identify conflicts, define input for items design and infrastructure. Then the various equipment is procured: verify and validate design data, follow-up manufacturing, fiducialize equipment, build supports. Lastly global installation: check equipped building, define survey framework, install and pre-align equipment on supports, move assemblies to their final location, survey actual position and adjust to theoretical position. The whole chain of operations from a layout to a real beam in MedAustron is illustrated. The help from item-driven data management is emphasized. Grouping all activities within a single team favors interactions between stakeholders and consistency of activities.

TUPS076	The Specification Process for the Large Scale Accelerator Project FAIR	alignment, antiproton, target, controls	1713
	U. Weinrich GSI, Darmstadt, Germany
	The project FAIR is a large scale international accelerator facility with a high complexity within the accelerator complex. The project is owned by the recently founded FAIR GmbH while the physical-technical layout of the accelerator part of the facility is under the responsibility of GSI. This is the so-called two company model. Most of the accelerator subsystems and components are foreseen to be delivered In-Kind by accelerator institutes from Europe and Asia. In addition direct procurement is foreseen for those components not covered by in-kind-contributions or being very critical in time. Furthermore procurement has already started of components covered by special agreements and funding.

Yamamoto KEK, Ibaraki, Japan
	When the unprecedented scale of earthquake occurred in Japan on the afternoon of March 11, 2011, PF ring and PF-AR, two synchrotron light sources in KEK, also suffered various damages. At PF ring, a formed bellows in a wall current monitor was broken, and atmospheric air rushed into the beam duct. At PF-AR, which is installed in the underground tunnel, the alignment of the ring magnets seemed to be disordered to an order of ten mm. At both rings, a lot of electronics racks and toolboxes in the control rooms or in the experimental halls were tilted or tipped over. It was extremely fortunate that the user operation had just been stopped on the morning of that day, and all the gate valves in the rings and to the beam lines had already been closed for the scheduled shutdown. A wide area blackout took place at the big earthquake, and the electric power for the accelerator was interrupted over the next two weeks because of temporal shortage of the electricity in the eastern part of Japan. In April, we could start detailed investigation of machine damages and repair works towards recommissioning of the rings before the summer and resumption of the user operations in the autumn.
