Status of Niowave/roark Ilc Vendor Qualification Tests at Cornell*

چکیده
To build the ~14,000 cavities required for the ILC each of the three world regions must have a sizable industrial base of qualified companies to draw cavities from. Two of these companies, Niowave Inc. and C.F. Roark Welding & Engineering Co., Inc, recently manufactured six 1.3 GHz single-cell cavities for qualification purposes. All six cavities achieved gradients above 25 MV/m before they were limited by the available RF power (Q-slope) or quenched. This paper will report the results of cold tests for all six cavities and on the causes of quench determined by 2 sound detection and optical inspection.

Ilc Testing Program at Cornell University
Cornell University’s superconducting cavity development program is one contributor to the global collaborative effort on critical SRF R&D for the ILC. We conduct R&D in support of the baseline cavity development as well as several alternate cavity development paths. For the baseline program we are preparing and testing ILC cavities. We have developed a new quench detection system and successful...
متن کاملFast Ion Instability Simulations for CesrTA
In 2008, it has been proposed to convert the Cornell Electron Storage Ring (CESR) into a test accelerator, called CesrTA, for the proposed International Linear Collider (ILC) damping rings. One of the effects to be studied in CesrTA is fast ion instability. An electron beam ionizes residual gas in the vacuum chamber, resulting in positive ions being trapped in the beam’s potential. Fast ion ins...
متن کاملISO 26262 - Exemplary Tool Classification of Model-Based Design Tools
Tool classification is an important part of the tool qualification process required by ISO 26262 since it determines the required confidence level for each tool in use. To cover the variety of tools used by practitioners, the standard only provides a framework for tool classification and leaves it up to the applicant to instantiate this framework. To illustrate the ISO 26262 tool classification...
متن کاملStatus of the ATF extraction line laser-wire
The Accelerator Test Facility (ATF) at KEK offers a very low emittance micrometre sized beam of 1.28 GeV electrons close from the conditions expected at the International Linear Collider (ILC). The ATF should soon be able to provide a bunch spacing similar to that of the ILC. This accelerator being a test facility it is possible to have dedicated machine time with custom beam optics for our tes...
متن کاملVendor Managed Inventory of a Single-vendor Multiple-retailer Single-warehouse Supply Chain under Stochastic Demands
In this study, a vendor-managed inventory model is developed for a single-vendor multiple-retailer single-warehouse (SV-MR-SV) supply chain problem based on the economic order quantity in which demands are stochastic and follow a uniform probability distribution. In order to reduce holding costs and to help balanced on-hand inventory cost between the vendor and the retailers, it is assumed that...
