Toshiaki Tauchi | 17 March 2011A huge 9.0-magnitude earthquake descended on us at about 14:46 on 11 March 2011 Japan standard time. The ATF (accelerator test facility) was operating for ATF2 beam-tuning and we were going to have a background study for the interaction point beam size monitor.

Rika Takahashi | 17 March 2011As many people in the world already know, Japan is currently dealing with its worst disaster: Japan's biggest earthquake on record and the fourth largest in history. Thousands of lives have been lost. Tens of thousands people are forced to evacuate and live without basic necessities. Hundreds of thousands are still missing.

Min Zhang | 6 January 2011From 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.

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.
