On 20 December, members of the Accelerator Division SRF Electron Linac Department and the Technical Division SRF Development Department successfully brought the first accelerating cavity in Cryomodule 2 to a gradient of 31.5 megavolts per meter, the gradient required for the proposed International Linear Collider. The achievement demonstrates the cavity's successful integration into the cryomodule.

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 0.8×10^10. A Japanese cavity now fulfilled those requirements for the first time at a test which took place at the Superconducting radiofrequency Test Facility (STF) at KEK, adding momentum towards future mass production.

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.

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 role in the growing ILC R&D programme at Fermilab.

Last January, engineers from the DAPNIA laboratory in Saclay France qualified a new electropolishing facility for single cell cavities. Their first electropolished cavity reaches a promising result, above 42 MV/m (megavolts per metre) of accelerating gradient. It allows them to join the global R&D effort on these cavity treatments.
