In the last decade, ACCEL has manufactured a variety of prototype SRF cavities but also more than 100 TESLA shape 1.3 GHz 9 cell cavities and more than 100 SNS 805 MHz 6-cell cavities. For the ILC R&D at FNAL, we have delivered 12 ILC 9-cell 1.3 GHz cavities and are currently producing 12 additional such cavities. ACCEL is prepared for the industrial production of cavities, couplers and also the module assembly for the XFEL. We have internally evaluated the needs and costs for an in house production of the XFEL cavities. Within an industrial study we have analysed the coupler production for the XFEL, developed a series production adapted XFEL coupler design based on the TTF-III coupler and determined the costs for the series production. ACCEL participated also in a module assembly study and investigated the costs for manpower and infrastructure to manufacture the needed modules for the XFEL within the forseen time of three years. Last year ACCEL was contracted by DESY to built up an industrial plant for electropolishing 1.3 GHz 9 cell cavities. This plant is in routine operation since November 2007 and we have sucessfully electropolished the first series of 10 cavities for DESY.

Advanced Energy Systems, Inc. has recently completed manufacture of four standard 9-cell TESLA-style ILC cavities, six single-cell ILC prototype cavities, six 9-cell symmetric ILC cavities, and one 9-cell re-entrant cavity of the Cornell design. This paper will present an overview of these fabrication projects and of the evolution of AES capability in cavity manufacturing. To date four of the 9-cell ILC cavities have been tested, the six single-cell cavities have been tested, and the 9-cell reentrant cavity has been tested. Preliminary results will be shown.

In 2006, AES performed a US based industrial Cost Study of RF units in production quantities sufficient for the ILC. During this study detailed costs were estimated for the fabrication steps of the SRF cavities in high production quantities. In late 2007, AES carried out a more detailed study specifically oriented toward optimizing the high production methods of only the SRF cavities to arrive at a best estimate of cost. We have found that the revised estimate shows a 34% reduction in cavity fabrication cost. We have optimized many of the machining and welding steps to take advantage of automated operations were possible. Our high production cost estimates were based upon actual machining, welding and parts handling times derived during the prototype fabrication of ILC type cavities at AES. These values were then applied with learning as appropriate to more automated operations to reduce labor costs. In addition, the type and size of e-beam welding machines was optimized. We found that the use of all single chamber welders covering three specific sizes was most cost effective. Details of steps leading to the stated conclusions are presented herein.

Communications & Power Industries, Inc. (CPI) has active programs to refine key components for the European XFEL. These components, the fundamental power coupler and the multibeam klystron (MBK) are also suited for the International Linear Collider (ILC). CPI power couplers are manufactured to our customer's specifications using processes which are standard to the electron device industry as well as processes which are specific to power couplers. We have developed the capability of plating high-RRR copper on stainless steel. We have developed the capability of applying TiN coatings to ceramic windows. Both processes are done in-house under carefully controlled conditions. Both processes have been fully qualified. CPI has manufactured nearly 100 power couplers of various designs. Our presentation will focus on power couplers for the XFEL and the ILC. CPI is currently developing a second-generation, horizontal MBK for DESY. This MBK operates at 10 MW, at an RF frequency of 1.3 GHz, 1.5 ms pulse length, and 10 Hz pulse repetition rate. Our presentation will provide an update on this development program.

Directional couplers have always been critical elements in the RF feed systems for accelerator structures. Until now, however, such devices have been confined to areas outside of the high vacuum cavity feeds. The level control of the RF signal required at the cavity inputs is continually increasing and it has become apparent that a directional coupler design for the high vacuum side of the system is necessary. The following paper highlights a novel coupler design to allow high vacuum directional couplers to be realized. Results are presented for both electrical and mechanical characteristics for an L-band device.

The 700m-long 8 GeV XFEL that was launched by RIKEN is now under construction and will be operational in FY 2010. The strong point of the XFEL facility in Japan is compact under keeping high-performance by applying Spring-8 numerous breakthroughs in accelerator-driven light sources technology. In order to support the high-performance of XFEL, the building was designed with a few architectural ideas. In this paper we introduce the design of building foundation and ground so as to control the transformation of floor which the devices are fixed to, and the design of air conditioning so as to control the temperature change around the devices.

SOLEIL is a third generation synchrotron light source located near Paris. Due to the high performance required for SOLEILs diagnostics, a special production procedure was tailored. During the production of 131 Beam Position Monitors (BPM) more than 500 feedthroughs were inspected; all of them passed strict tests at different stages of the production: Leak test (< 10-10 mbar l/s), Dimensional control (Displacement <0.050 mm), Vacuum test (Specific Outgassing < 10-12 mbar l/s cm2, Residual Gas Analysis) and Electrical test (Capacitance measure ~8pF, Insulation >50 MΩ, Impedance <0.1 Ω). All the established procedures and tests have been performed in a tight partnership that was more than a simple contractual framework, in which an intensive collaboration led to a knowledge transfer between SOLEIL and Rial Vacuum. The result has been a high percentage of success (few feedthroughs over 500 were replaced) during preliminary tests and a deeper knowledge of BPM problem solving; in this article are presented different test procedures to obtain high quality and high performance BPMs.

After initial evaluation of particle therapy in research institutions this technology is now transferred into hospitals for cancer treatment. Industrial companies are key partners for this transfer, not only as suppliers for the medical product, but also as general contractors for the overall project realization and the technical operation of such facilities. Their solutions support the entire patient workflow from patient diagnosis, therapy planning, treatment and follow up in addition to the delivery of the accelerator technology. The presentation will give an overview of the present industrial solutions in this field and perspectives for the future.

Collaborating with Industry: Lessons from the LHC Megaproject
|
1963 |
|
|
|
|
The LHC is an accelerator with unprecedented complexity, requiring an investment substantially exceeding other accelerator projects. Industry from many countries played a key role during all phases of the LHC project, for research, development, production, assembly of components and installation. There are many different ways of working with industry, however, some constraints due to the status of CERN as an inter-governmental organisation have to be taken into account. The presentation will review the experience when collaborating with industry with the objective of profiting from the lessons during LHC construction for future projects of similar size, such as FEL at DESY, FAIR, ILC and ITER.

As part of the EUROFEL Design Study, two industrial partners recently took part in the assembly of superconducting TESLA modules for FLASH. The aim was to transfer the module assembly knowledge to industry and to analyse the assembly sequence to perpare for industrial production for future projects such as the XFEL. This talk should discuss the conclusions of this study and identify issues that must be considered when transferring SRF technology to industry.

To be successful, accelerator projects require close interaction with industry for design, engineering and construction. Partnership and cooperation between institutes and industry is a means to transfer knowledge and foster innovation in the private sector, while the public sector benefits from best practices, efficient use of resources and pooled knowledge. An overview of partnerships between institutions and industry is given with examples from active projects.
