MOOCA02	RFQ Developments at CEA-IRFU	rfq, linac, proton, cavity	42
	O. Piquet CEA/DSM/IRFU, France
	Vane RFQs are particularly well suited to high intensity proton acceleration, since they offer minimal RF power losses and best accelerating field accuracy. Cea-Irfu is involved in several developments of 4 vane RFQs namely IPHI, Spiral2, Linac4 and ESS. This paper gives an overview of the design flow and tools developed at Irfu in order to design, tune, condition and commission RFQs. SPIRAL2 RFQ will be mainly used to illustrate this design flow. This CW RFQ requires 180 kW to achieve the nominal accelerating voltage. It can accelerate a 5 mA proton or deuteron beam (A/Q=1 and 2) or a 1 mA ion beam with up to A/Q=3 at 0.75 MeV/A. Conditioning and commissioning of this RFQ are actually in progress.

MOPMW033	Acoustic Localization of RF Cavity Breakdown: Status and Progress	cavity, collider, experiment, simulation	470
	P.G. Lane, P. Snopok, Y. Torun Illinois Institute of Technology, Chicago, Illinois, USA A.V. Kochemirovskiy University of Chicago, Chicago, Illinois, USA
	Current designs for muon accelerators require high-gradient RF cavities to be placed in solenoidal magnetic fields. These fields help contain and efficiently reduce the phase space volume of source muons in order to create a usable muon beam for collider and neutrino experiments. It has been found that placing normal conducting RF cavities in strong magnetic fields 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 localize the source of breakdown sparks inside the cavity. These sparks generate thermal shocks to a small region of the inner cavity wall that can be detected and localized using microphones attached to the outer cavity surface. Presented here are the algorithms for and results from localizing simulated and experimental acoustic data from the Modular Cavity at the MuCool Test Area at Fermilab.

	The recent development of semiconductor technology has proved that a solid-state RF amplifier is an attractive alternative high-power RF source for numerous accelera-tor applications. Because of the great redundancy and reliability of solid-state amplifiers present in many facili-ties worldwide, the development of a kW-level RF power per module using compact planar baluns has also been undertaken in NSRRC. Ten amplifier modules are com-bined to achieve stable output power 8 kW as an initial conceptual realization of a basic power unit within a combined network. This article describes each portion of the amplifier with the experimental results.

MOPOW006	Planning and Controlling of the Cold Accelerator Sections Installation in XFEL	laser, electron, free-electron-laser, vacuum	716
	M. Bousonville, S. Choroba, F. Eints DESY, Hamburg, Germany
	The installation of the main linear accelerator in the 2 km European XFEL (X-Ray Free-Electron Laser) tunnel is currently under way. The accelerator consists of nine so-called cryo-strings. A typical cryo-string comprises 12 accelerator modules, which will be fed by three RF stations. Furthermore, the installation of electronic racks, cables, power and water supply etc. takes place. To enable a most effective installation of the accelerator components, planning and controlling methods, which had first been developed for the RF system work package, were adapted for the entire main linear accelerator. As a first step, a process plan was developed in cooperation with the work package leaders. On the basis of this plan, the installation process is promoted by several measures: The status of the installation is precisely registered by weekly queries which enable monitoring of the progress and feedback to everyone involved. With this information at hand, the installation process can be controlled and plan deviations can be corrected. Furthermore, the experience gained at one cryo-string is used to optimise the plan for the next cryo-string installation.

	Y. Suetsugu, H. Hisamatsu, T. Ishibashi, K. Kanazawa, K. Shibata, M. Shirai, S. Terui KEK, Ibaraki, Japan
	The SuperKEKB, an electron-positron collider with asymmetric energies in KEK, has started the first commissioning with beams this year. One of major tasks in the commissioning is the beam scrubbing of new beam pipes in order to increase the beam lifetime and to decrease the background noise of the particle detector in the coming physics run. The temperatures and the vacuum pressures of new vacuum components, such as the bellows chambers, gate valves and the beam collimators, should be checked in this run. The decrease rate in the vacuum pressure are measured to estimate the vacuum scrubbing effect. Reported here will be the results obtained during the first commissioning and the present status of the vacuum system.

	The rigorous process in place at CERN to approve and follow-up the implementation of any modification of the LHC machine and its Injectors is presented in this paper. Our methodology implies the support of three teams, in charge of the configuration management, the scheduling and safety coordination, and the 3D integration studies. At each stage of the project the support of the three teams evolves, to provide the adequate support in the preparation phase and during the technical stops and long shutdowns. The formal roles and the processes used to govern the interaction of the Integration, Configuration and Coordination teams, and their relation to the project teams during the preparation and implementation phases, for activities to be performed in LHC and its injector chain are described and discussed.

	The traditional alarm systems usually set up/low limit for various signals. When the acquired values exceed the limits, the alarm system would be activated. The proposed system in this article can focus on various possible events with many kinds of signals for response judgments. During alarm calling period, data can also be announced and recorded. The system can also monitor various events according to different time shifts. Integrating LabVIEW, mobile phone, AT-command and Bluetooth communication, the system can handle factory broadcast, sending E-mail and SMS message. The above sound and words messages can be set directly at the home-made software interface. The new intelligent alarm system can eliminate the procedure made by man with the added event recording, system stability improvement and debugging function in wider application fields.

THPMY032	Air Conditioning System Control Study and Improvement for Transient Events in the TLS Storage Ring	controls, storage-ring, dipole, operation	3728
	J.-C. Chang, C.S. Chen, C.Y. Liu, Z.-D. Tsai NSRRC, Hsinchu, Taiwan
	It has been studied and verified that thermal effect is one of the most critical mechanical factors affecting the beam stability. There are many accelerators have controlled the global air temperature variation in the storage ring tunnel within ±0.1C during stable beam operation in the world. However, some transient events, such as unexpected beam loss or beam trip will clearly affect air temperature variation. Moreover, machine shutdown will change the air conditioning status radically. It will also take time to reach a stable air temperature after machine shutdown. This paper presents effects on the air temperature by those transient events and improvement schemes.

	Y.-H. Liu, C.S. Chen, Y.-C. Chung NSRRC, Hsinchu, Taiwan
	The purpose of this paper is to evaluate the vibration level and spectrum for TPS deionized water pumps. The utility systems started to operate from the beginning of 2014, some of deionized water pumps produced higher vibration level and noise during operation. The possibly reason could be not appropriated installation and commission test. In order to figure out the status of these deionized water pumps, the vibration analysis become needed. After vibration test, the booster(BO) and copper(CU) deionized water pump systems generate higher vibration level. According to the vibration test results, the pump is repair and maintain. Although there is some problems for TPS deionized water pumps, the vibration test is still one important way to maintain utility systems. The utility systems could prevent malfunction through regular vibration inspection.

The SuperKEKB, an electron-positron collider with asymmetric energies in KEK, has started the first commissioning with beams this year. One of major tasks in the commissioning is the beam scrubbing of new beam pipes in order to increase the beam lifetime and to decrease the background noise of the particle detector in the coming physics run. The temperatures and the vacuum pressures of new vacuum components, such as the bellows chambers, gate valves and the beam collimators, should be checked in this run. The decrease rate in the vacuum pressure are measured to estimate the vacuum scrubbing effect. Reported here will be the results obtained during the first commissioning and the present status of the vacuum system.

The rigorous process in place at CERN to approve and follow-up the implementation of any modification of the LHC machine and its Injectors is presented in this paper. Our methodology implies the support of three teams, in charge of the configuration management, the scheduling and safety coordination, and the 3D integration studies. At each stage of the project the support of the three teams evolves, to provide the adequate support in the preparation phase and during the technical stops and long shutdowns. The formal roles and the processes used to govern the interaction of the Integration, Configuration and Coordination teams, and their relation to the project teams during the preparation and implementation phases, for activities to be performed in LHC and its injector chain are described and discussed.

After the successful development of the IHEP01 and IHEP02 1.3GHz 9cell superconducting cavity, we developed a 1.3GHz Tesla-Like 9cell superconducting cavities in collaboration with KEK. The cavity was made by niobium material produced in OTIC, Ningxia, China. After completeing welding, leakage check, BCP, HPR, we sent the cavity to KEK and used the standard procedures of ILC cavity for processing. These include electron polishing, vacuum furnace outgassing, tuning for field flatness and frequency, light EP, baking and vertical test. We target to have a high Q0 cavity for this experiment. In this paper, we will report the experimental status of the IHEP03 cavity.

The traditional alarm systems usually set up/low limit for various signals. When the acquired values exceed the limits, the alarm system would be activated. The proposed system in this article can focus on various possible events with many kinds of signals for response judgments. During alarm calling period, data can also be announced and recorded. The system can also monitor various events according to different time shifts. Integrating LabVIEW, mobile phone, AT-command and Bluetooth communication, the system can handle factory broadcast, sending E-mail and SMS message. The above sound and words messages can be set directly at the home-made software interface. The new intelligent alarm system can eliminate the procedure made by man with the added event recording, system stability improvement and debugging function in wider application fields.

It has been studied and verified that thermal effect is one of the most critical mechanical factors affecting the beam stability. There are many accelerators have controlled the global air temperature variation in the storage ring tunnel within ±0.1C during stable beam operation in the world. However, some transient events, such as unexpected beam loss or beam trip will clearly affect air temperature variation. Moreover, machine shutdown will change the air conditioning status radically. It will also take time to reach a stable air temperature after machine shutdown. This paper presents effects on the air temperature by those transient events and improvement schemes.

The purpose of this paper is to evaluate the vibration level and spectrum for TPS deionized water pumps. The utility systems started to operate from the beginning of 2014, some of deionized water pumps produced higher vibration level and noise during operation. The possibly reason could be not appropriated installation and commission test. In order to figure out the status of these deionized water pumps, the vibration analysis become needed. After vibration test, the booster(BO) and copper(CU) deionized water pump systems generate higher vibration level. According to the vibration test results, the pump is repair and maintain. Although there is some problems for TPS deionized water pumps, the vibration test is still one important way to maintain utility systems. The utility systems could prevent malfunction through regular vibration inspection.

The measured result will be analyzed and used to further improve the performance of power system. Furthermore, a partial discharge monitoring system was also installed to monitor the phenomena of electric discharges. Using the ultra high frequency discharge sensor, the magnitude and the pulse-per-second of discharge are measured and analysed. It allows the electrical engineers to diagnose the degradation of insulation of the electric equipment beforehand to reduce the power failure.

The NSLS-II at Brookhaven National Laboratory (BNL) started the user beam service in early 2015, and is currently operating 13 of the insertion device (ID) and beamlines as well as constructing new beamlines. The fast machine protection consists of an active interlock system (AIS), beam position monitor (BPM), cell controller (CCs) and front-end (FE) systems. The AIS measures the electron beam envelop and the dumps the beam by turning off RF system, and then the diagnostic system provides the post-mortem data for an analysis of which system caused the beam dump and the machine status analysis. NSLS-II post-mortem system involves AIS, CCs, BPMs, radio frequency system (RFs), power supply systems (PSs) as well as the timing system. This paper describes the AIS architecture and PM performance for NSLS-II safe operations.
