The new energy reach will permit significant extensions in research into kilometrww aspects of QCD. Areas of interest are Generalized Parton Distributions GPDsmeasurements at high-xBjorken, and the use of hybrid mesons to explore the nature of quark confinement.
The presentation will touch on the science and give some details of the accelerator plans. For sub systems that consist of many complex, identical pieces, in house fabrication is not an option as it was in the past, and so industrial procurement is required.
If industry has not developed the requisite technology in support of an active market product, technology transfer must be accomplished. The talk will review the circumstances when technology transfer is appropriate, and based on a review of large system procurements for Fermilab, SLAC, the SSC, SNS, the LHC and RHIC, it will outline general guidelines that have emerged for what is required of project managers and industrial vendors to increase the probability of successful technology transfer and procurement.
The guidelines are generally not dependent on specific national acquisition regulations, and therefore are relevant for international projects. The availability of high-power, high-brilliance sources of tunable photons from energy-recovered Free Electron Lasers is opening up whole new fields of application of accelerators in industry.
This talk will review some of the ideas that are already being put into production, and some of the newer ideas that are still under development. The quadrupoles of the LNLS storage ring are divided into families with two or six units, each one being supplied by an only current source. Some experiments performed by the accelerator physics team require different currents for quadrupoles of a same family.
Jilometrw, there is an interest in obtaining lower steps in the control of their currents. These were the main reasons that required the development of an active shunt. It was tested with a two-quadrupole family power supply. The full bridge topology was chosen, where the pulse width for the positive and negative output przyfody are not the same, which gives an average output current different from zero. Some waveforms and results are shown, such as the long-term killometrw and output current ripple.

Some measurements made in the storage ring electron beam using the active shunt are also described. Recently the substitution of the older family of orbit corrector power supplies of the LNLS electron storage ring was proposed and a new family has been developed.
The new model incorporates additional features such as natural ventilation, unit power factor and shorter 1800 time to reference changes. Moreover, higher efficiency and lower weight and przytody were obtained. This family has three stages of power processing. The second stage is an isolated half-bridge with two symmetric adjustable DC outputs from 0 to 40V.
Some results obtained pezygody this power supply were: We present the results of the commissioning of the first Elliptically Polarizing Undulator to be installed at the 1.
The undulator is designed to provide UV and soft X-ray photons from eV up to 1 keV with kilkmetrw polarization control. It uses the APPLE II design with 50 mm period and 22 mm gap and allows for both kilomettw and anti-parallel longitudinal motion of its magnet cassettes. We present the commissioning results including the measured orbit and tune perturbations as well as the non-linear effects of the undulator fields on the stored beam and the corresponding impact on the beam lifetime.
The system offers a wide range of applications for managing complexity: It enables 3D CAD design collaboration, supports the manufacturing and preparation processes of s. The system is now also adopted by the ILC for the collaborative 3D CAD design of cryomodules in the three regions and for change management of the baseline configuration kilpmetrw.
In addition to general engineering requirements, the EDMS supports ad-hoc teamwork, provides mechanisms for process industrialization and offers powerful yet easy-to-use web frontends.

In the European X-ray FEL 32 superconducting cavities 4 cryomodules with 8 cavities per module are connected to one 10 MW multibeam klystron through a waveguide distribution system.
The XFEL tunnel has limited space for the waveguide system and therefore a new more compact waveguide distribution has been developed.
The waveguide distribution is based on a binary cell which consists of two circulators connected to a shunt tee with integrated phase shifters. Four binary cells are combined by three asymmetric pretunable shunt tees. The asymmetric shunt tees allow to change the RF power for each pair of cavities and to reach the maximum cryomodule gradient. In this paper we will present the status of the waveguide distribution system and report on the development of the different new waveguide components.
For that an optical synchronisation system is developed for FLASH at DESY, that is based on optical pulse train which carry the timing information encoded in its precise repetition rate. The optical pulse train has to be converted into an RF signal to provide a local reference for calibration and operation of RF based devices.
The drift and jitter performance of the optical to RF converter influences directly the phase stability of the accelerator.

Three different methods for optical to RF converters, namely the direct photodiode detection, injection locking and a sagnac loop interferometer are currently under investigation. In this paper we concentrate on the jitter and drift performance of the direct photodiode conversion and show its limitations from measurement results. The Feedback system was fully automated, in order to relieve the operator from manual control during system operation.
The proton bunch length is significantly reduced as is the stretching of the bunches over runtime. Without additional damping the bunch length is about 1. With the new feedback system in operation the bunch length could be decreased to 1.
System optimization points were found in automatic gain adjustment during acceleration ramp, oscillation level triggering and timing of kicker pulse to kilmetrw. We describe the commissioning of the multibunch feedback system and the adjustment procedures. A performace overview after one year of operation is given. The master oscillator and phase reference system at FLASH must przyvody several rf reference frequencies to widely spread locations with low phase noise and small long term phase drifts.
The phase noise requirements of the Przyvody reference is of the order of 0. The frequency kioometrw system employs a temperature stabilized coaxial line for pgzygody power distribution and a fiber optic system for the monitoring of phase drifts.
Presented are the the concept, design and performance measured in the accelerator environment. An optical synchronization system based on the timing-stabilized distribution of ultra-short optical pulses has been proposed for next generation light sources, e.
This paper describes the status of the optical master oscillator, which consists of two mode-locked Erbium-doped fiber lasers running in parallel. It globally corrects the closed orbit at 10 kHz rate using all the BPMs and corrector magnets of the storage ring. The Libera Electron device has been used to upgrade the original detectors in order to provide micrometric accuracy and fast data rate of the beam position measurements.
The article reports the experience gained during the commissioning of the system and the first operational results. Non Evaporable getter NEG coating technology, developed at CERN in the late 90s, is an effective pumping solution for conductance limited vacuum chambers.
It reduces thermal out-gassing and provides distributed pumping ability, allowing the achievement of very low pressure. NEG films do show additional interesting features, like low secondary electron yield and low gas de-sorption rates under ions, electrons and photons bombardment. For these reasons, large scale adoption of NEG coated chambers is now a reality and several leading edge kilometw will soon benefit from it.
A critical issue for the 1180 application of this technology is the ability to deposit NEG coatings in a reproducible and reliable way all along a pipe.
This is particularly important for narrow-gap or specially shaped chambers which pose severe challenges in term of film thickness distribution, chemical ptzygody and sorption properties. A dedicated study was carried kilomeetrw to fully understand the deposition process as a function of the sputtering parameters and the chamber geometry.
Results obtained do allow to optimize the coating process and ensure that film requirements in a given application are met. Non Evaporable Getter NEG coated chambers have been used in various accelerators facilities and synchrotrons since some years. Initially, NEG coated chambers were mounted in small amounts in specific locations, covering a minor fraction of the accelerator surfaces exposed to vacuum. More recently, NEG coated chambers have been adopted to a larger degree in several projects, becoming an integral part of the machine design.
LHC, whose commissioning is expected inwill use 6 km of coated pipes, to be the largest machine ever using this technology. Coating a large number of chambers poses challenges in term of process industrialization, product inspection and quality assurance. Main technological issues faced and procedures adopted to ensure product reproducibility and quality are presented and discussed.
The Virtual Accelerator has a mathematical model of the beam dynamics in order to simulate the behavior of the beam and enables the revolutionary commissioning and operation of an accelerator.
Additionally, we have constructed the commissioning tool based on the Virtual Accelerator.
We will present a current status of the Virtual Accelerator system and some commissioning tool. Ikeda Visual Information Center, Inc.
XAL was initially developed at SNS kilomefrw has been described at length in previous conference proceedings e. The fundamental tenet kilomwtrw XAL is to provide a consistent, high-level programming interface, along with a set of high-level application tools, all of which are independent of the underlying machine hardware.
Control applications can be built that run at any accelerator site where XAL is installed. Of course each site typically has specific needs not supported by XAL and the framework was designed with this in mind: For example, we have added permanent magnet quadrupoles and additional space charge capabilities such as off-centered and rotated beams and bending magnets with space charge. We present the physics models for the upgrades as well as the software architecture supporting them.
A beam current feedback system to stabilize the long-time operation of thermionic cathode RF-Gun has been developed in Kyoto University FEL facility where a 4. However, the back-bomberdment effect seriously increases the temperature of the cathode surface, and thus the stable operation was quit difficult without continuous control of the cathode temperature or the beam current.
We have tried to stabilize the beam current by using a feedback system. The beam current was monitored with current kilometwr, which was located at the exit of the gun or at the downstream of the energy analyzer, was read by oscilloscope.
As a result, the long term stability of the beam current dramatically improved. A commissioning software framework and a database system have been developed for the commissioning.
Commissioning tools developed during the commissioning will be presented in detail. This system is integrated with longitudinal oscillation measurement przygldy, fast vector control, fiber notch filter and bunch current detection system.
The detail of the two fronts will be shown. Some experimental results by this system are also present in this paper, as phase-space tracing, mode dumping rate, and feedback experiments. This work is supported by National Nature Science Foundation of China under Grant A virtual control system designed to control and monitor the process of a cyclotron virtual prototyping is presented in this paper. Based on the feature of cyclotron, a distributed control structure is proposed according to the knowledge of software engineering.

Any additional functions can be extended easily in this system in future. Operating console and storage module for operators in the control room has been programmed on PC and SUN of the operator interface. Because some power supplies have analog interfaces, we chose ATEC Analog Input To Ethernet Converter to monitor their output currents and voltage by supporting the protocol conversion function.
The false BPM reading resulting from the BPM vacuum chamber motion due to thermal load change by synchrotron radiation is compensated by the real-time monitoring of the chamber position in the PLS orbit feedback system. In this paper, we will describe how serious the BPM chamber motion are and how well it is compensated.
