Daisy Yuhas | 23 August 2012Physicists need to understand each accelerator cavity individually before assembling a collider. One of the cavity characteristics physicists measure is called the cavity quality factor, Q factor for short. The LCpedia series continues.

Rika Takahashi | 9 December 2010Designing 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.

Barry Barish | 4 November 2010One of our most visible and important ILC R&D short-term milestones has been to demonstrate production of ILC superconducting radio frequency cavities with gradient of greater than or equal to 35 megavolts per metre (MV/m) and Q0 = 8x10^9 and 50 percent production yield. [...] Today I announce the successful achievement of that important 2010 milestone.
