MOYGB3	Commissioning of NSLS-II	insertion, emittance, damping, lattice	11
	F.J. Willeke BNL, Upton, Long Island, New York, USA
	NSLS-II, the new 3rd generation light source at BNL was designed for a brightness of 10²² photons s^-1 mm^-2 mrad^-2 (0.1%BW)^-1. It was constructed between 2009 and 2014. The storage ring was commissioned in April 2014 which was followed by insertion device and beamline commissioning in the fall of 2014. All ambitious design parameters of the facility have already been achieved except for commissioning the full beam intensity of 500 mA which requires more RF installation. This paper reports on the results of commissioning.

MOPWA041	Investigation of Radiation Damage of Insertion Devices at PETRA III due to Particle Losses using Tracking Results with SixTrack	radiation, undulator, insertion, synchrotron	203
	G.K. Sahoo, M. Bieler, J. Keil, A. Kling, G. Kube, M. Tischer, R. Wanzenberg DESY, Hamburg, Germany
	PETRA-III is a 3rd generation synchrotron light source dedicated to users at 14 beam lines with 30 instruments since 2009. This operates in 40, 60, 480 or 960 bunches with 100 mA at an electron beam energy of 6 GeV. The horizontal beam emittance is 1nmrad while a coupling of 1% amounts to a vertical emittance of 10 pm-rad. The low emittance is achieved by deploying 80m of damping wigglers in two sections in west and north. Some of these undulators and wiggler devices have accumulated total radiation doses of about 100 kGy. Visible corrosion at the magnet structures of some permanent magnet undulators is seen. High dose rate measured regularly by Thermo Luminescent Dosimeters (TLDs) are monitored, which lead to inspect the magnetic field of all insertion devices in the PETRA tunnel. We are investigating particle losses with tracking simulation using SixTrack to gain a certain understanding of the radiation damage of the insertion devices. The goal is to develop a strategy to safeguard the insertion devices from further radiation damage.

MOPWI010	Design and Development of a Beam Stablity Mechanical Motion System Diagnostic for the APS MBA Upgrade	detector, vacuum, insertion, ground-motion	1164
	R.M. Lill, G. Decker, N. Sereno, B.X. Yang ANL, Argonne, Ilinois, USA
	Funding: Results shown in this report result from work performed at Argonne National Laboratory operated by UChicago Argonne, LLC, for the U.S. Department of Energy under contract DE-AC02-06CH11357. The Advanced Photon Source (APS) is currently in the conceptual design phase for the MBA lattice upgrade. In order to achieve long-term beam stability goals, a Mechanical Motion System (MMS) has been designed to monitor critical in-tunnel beam position monitoring devices. The mechanical motion generated from changes in chamber cooling water temperature, tunnel air temperature, beam current and undulator gap positon causes erroneous changes in beam position measurements causing drift in the X-ray beam position. The MMS has been prototyped and presently provides critical information on the vacuum chamber and BPM support systems. We report on first results of the prototype system installed in the APS storage ring.

MOPWI011	Beam Stability R&D for the APS MBA Upgrade	feedback, diagnostics, insertion, controls	1167

	Funding: Results shown in this report result from work performed at Argonne National Laboratory operated by UChicago Argonne, LLC, for the U.S. Department of Energy under contract DE-AC02-06CH11357. Beam diagnostics required for the APS MBA are driven by ambitious beam stability requirements. The major AC stability challenge is to correct rms beam motion to 10% the rms beam size at the insertion device source points from 0.01 to 1000 Hz. The vertical plane represents the biggest challenge for AC stability which is required to be 400 nm rms for a 4 micron vertical beam size. Long term drift over a period of 7 days is required to be 1 micron or less. Major diagnostics R&D components are improved rf beam position processing using commercially available fpga based bpm processors, new XRay beam position monitors sensitive only to hard X-rays, mechanical motion sensing and remediation to detect and correct long term drift and a new feedback system featuring a tenfold increase in sampling rate and a several-fold increase in the number of fast correctors and bpms. Feedback system development represents a major effort and we are pursuing development of a novel algorithm that integrates orbit correction for both slow and fast correctors down to DC simultaneously. Finally a new data acquisition system (DAQ) is being developed to acquire streaming data from all diagnostics.

TUPJE015	Beta Function Matching and Tune Compensation for HLS-II Insertion Devices	storage-ring, insertion, undulator, electron	1647
	B. Li, J.Y. Li, W. Xu, K. Xuan USTC/NSRL, Hefei, Anhui, People's Republic of China
	In order to increase its brightness and improve the performance, the Hefei Light Source (HLS) was completely renovated from 2010 to the end of 2014. The magnet lattice of the new storage ring consists of four double bend achromatic (DBA) cells. There are eight straight sections which can be used to install up to 6 insertion devices (IDs). Currently, five insertion devices have been installed in the storage ring. It is known that the dynamics of the electron beam motion in the storage ring would be influenced by the insertion device, depending on its physical properties. In order to keep high performance operation of the storage ring and make the insertion device transparent to the rest of the storage ring, a complex compensation scheme is developed to match the beta functions at both ends of a ID and perform transverse tune compensation. This scheme has been integrated into the EPICS based control system of the HLS-II. The result indicates that the scheme is very effective to compensate the impact of the insertion devices.

	R. Geometrante, M. Zambelli KYMA, Trieste, Italy M. Zambelli Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy
	Kyma was established in 2007 as a spin-off company of Elettra-Sincrotrone Trieste, to design, realize and install all the 18 undulators of FERMI, the seeded FEL, at the time being built at the Elettra lab in Trieste, Italy. For Kyma establishment, Elettra-SincrotroneTrieste formally transferred to the new company know-how and references relevant to Insertion Devices and, by a Knowledge Transfer monetarily evaluated, could participate to Kyma capital owning the 51% of the shares. In few years, Kyma became a well-known organization in the light source community. After more than forty Insertion Devices and sixty phase shifters designed and manufactured, Kyma is now recognized as a qualified partner for design and development of this kind of equipment. Some examples of Kyma industrial achievements in developing skills, knowledge, technologies methods of manufacturing transferred by Universities and Institution, will be presented. An example out of many: the joint effort between Kyma and Cornell University right now leading to the development of a new perspective into the ID world, i.e. the CHESS Compact Undulators (CCU).

WEPMA027	First Characterization of a Superconducting Undulator Mockup with the CASPER II Magnetic Measurement System	undulator, synchrotron, insertion, permanent-magnet	2815
	S. Gerstl, S. Casalbuoni, N. Glamann, A.W. Grau, T. Holubek, D. Saez de Jauregui, R. Voutta KIT, Eggenstein-Leopoldshafen, Germany C. Boffo, T.A. Gerhard, M. Turenne, W. Walter Babcock Noell GmbH, Wuerzburg, Germany
	Superconducting insertion devices (IDs) can reach, for the same gap and period length a higher field strength compared to permanent magnet IDs. Their performance depends strongly on the magnetic field quality. While the magnetic measurements technology of permanent magnet based IDs made significant progress during the last years, for superconducting IDs similar major developments are necessary. As a part of our R&D program for superconducting insertion devices at the ANKA synchrotron light source a measurement setup for conduction cooled superconducting coils with a maximum length of 2 m was built and commissioned. In the CASPER II (Characterization Setup for Phase Error Reduction) facility the magnet coils can be trained and tested for maximum current and field quality, including the local field distribution as well as the first and second field integrals. In this paper we shortly describe the CASPER II setup and focus on the capability of this measurement device by presenting the results of a superconducting undulator mockup with a period length of 20 mm.
