Jefferson Lab and IHEP renew accelerator cavity collaboration

Under the umbrella of the PRC-US Cooperation on High Energy Physics, Jefferson Lab and IHEP exchange notes on cavity R&D

| 17 November 2011

At a recent meeting between US and Chinese high-energy and nuclear physics laboratories, Jefferson Lab in Newport News, US, and the Institute for High Energy Physics (IHEP) in Beijing, China, renewed a partnership to collaborate on the development of superconducting accelerator cavities, including an ILC-type nine-cell cavity. It is a continuation of a collaboration that […]

From KEK: Japanese 9-cell SCRF cavity meets ILC specification

| 9 December 2010

Designing and fabricating an optimal accelerating cavity is not so simple. There are two important parameters scientists are looking for: the gradient of 35 megavolts per meter (MV/m) and the quality factor (Q0) of greater than 0.8×1010. A Japanese cavity now fulfilled those requirements for the first time at a test which took place at […]

China reaching the target gradient

Important progress on IHEP superconducting cavity

| 22 July 2010

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

| 25 November 2009

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 […]
