New start, new hope

| 6 January 2011 From 7 to 8 December 2010, the IHEP-KEK 1.3-gigahertz superconducting radiofrequency (SRF) technology collaboration meeting was held at the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences in Beijing. This was the third in a series of meetings held regularly since 2009. Eight high-energy accelerator experts from KEK and Kyoto University and nearly thirty researchers from IHEP participated.

China reaching the target gradient

9 September 2010 A 1.3-gigahertz TESLA-type nine-cell niobium superconducting cavity, named PKU3, as the third nine-cell cavity fabricated by the superconducting radiofrequency (RF) group at Peking University, Beijing, China, achieved an accelerating gradient of 28.6 megavolts per metre (MV/m) at an unloaded quality factor of 4×109 in its second vertical test at Jefferson Lab (JLab), USA on 9 August 2010. This cavity is the first nine-cell cavity with end group components in China reaching a gradient usable for the ILC. Category: Around the World | Tagged: , , , , ,

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 on the research and development of superconducting radio frequency (SRF) technology in China.

Four TESLA Cavities Delivered to Fermilab ILC cavity

| 20 October 2005 Four unprocessed TESLA cavities recently arrived at Fermilab for measurements and testing. The 9-cell, 1.3 Ghz cavities, manufactured by ACCEL in Germany, will be used to construct the first U.S. cryomodule for International Linear Collider R&D near the end of 2006.
