A 1.3-Gigahertz low-loss type large-grain nine-cell superconducting cavity called IHEP-01 produced at the Institute of High Energy Physics (IHEP) in Beijing, China, achieved an accelerating gradient of 20 Megavolts per metre in its first vertical test at KEK on 1 July. This may not be the design gradient yet, but it marks an important progress […]
What drives the development of technology
Director’s Corner 25 November 2009 Marc Ross What drives the development of technology? Today’s issue features a Director’s Corner from Marc Ross, Project Manager for the Global Design Effort. Five years ago, when superconducting radiofrequency (SCRF) technology was chosen for the International Linear Collider, there were precious few high-gradient, 35-Megavolts-per-metre (MV/m) cavities. Now the picture […]
Global effort for high-gradient ILC SCRF cavities
Director’s Corner 30 July 2009 Akira Yamamoto Global effort for high-gradient ILC SCRF cavities Today’s issue features a Director’s Corner from Akira Yamamoto, Project Manager for the Global Design Effort. I would like to thank Barry Barish for his 9 July Director’s Corner where he described the importance of and progress in the ILC superconducting […]
Improvements in high-gradient ILC SCRF cavities
Director’s Corner 9 July 2009 Barry Barish Improvements in high-gradient ILC SCRF cavities Developing high-gradient superconducting radiofrequency (SCRF) nine-cell cavities is one of the primary goals of our global R&D programme. Soon after we initiated the Global Design Effort (GDE) R&D and design programme for the International Linear Collider, we set the ambitious goal of […]
Past successes in superconducting RF are a good omen for the ILC
Hasan Padamsee and Charles Reece highlight successes in the evolution of superconducting RF technology and look to ILC and future developments.
One of the high-value R&D programmes for the ILC is to reliably reach gradients of 35 Megavolts per metre (MV/m) in one-metre long (9-cell, 1.3-Gigahertz) niobium cavities, the heart of the main linac. More than a dozen such cavities have demonstrated gradients between 35 and 40 MV/m at DESY, and more recently at Jlab. The […]
From Jefferson Lab News: ILC treatment of JLab cavity garners exciting result
For the last few years, Jefferson Lab staff members have used the lab’s unique facilities to test various accelerator components for a proposed next-generation collider, the International Linear Collider. Reminiscent of a stack of doughnuts, accelerator components called cavities energize particles for use in experiments that explore the smallest bits of matter. In preparing ILC […]
From CERN Courier: Viewpoint: SRF technology comes full circle
Accelerator builders should step back and re-assess decades of R&D into superconducting RF technology says Jefferson Lab’s Ganapati Rao Myneni. Nearly a half-century ago, researchers at Stanford University began investigating superconducting RF (SRF) acceleration. They would not have been surprised to learn that by 1994, SRF had come into large-scale use in Jefferson Lab’s Continuous Electron Beam […]
Progress on our Technical Design Phase goals
Director’s Corner 26 November 2008 Marc Ross Progress on our Technical Design Phase goals Today’s issue features a Director’s Corner from Marc Ross, Project Manager for the Global Design Effort. Last week several hundred scientists and engineers gathered at the new Forum Event Center of the University of Illinois at Chicago for LCWS 08 and […]
US-manufactured cavity achieves high gradient
Turkey, stuffing and pumpkin pie – all things you might appreciate on Thanksgiving. ILC scientists in the United States had something extra to be thankful for this year. On 21 November, the day before the Thanksgiving holiday in the US, a superconducting cavity manufactured by Advanced Energy Systems in Medford, NY, reached a high gradient […]
Fermilab’s new Horizontal Test Stand sees its first cavity
The newest resident in Fermilab’s Meson Detector Building is up and running. Last week, Fermilab scientists installed a nine-cell 1.3 GHz TESLA-style cavity into a cryostat in order to commission the new Horizontal Test Stand. Designed to test both 3.9 Ghz and 1.3 Ghz 9-cell niobium cavities, the Horizontal Test Stand will play an important […]
