A scientist’s report on the earthquake and KEK’s accelerator test facility

| 17 March 2011 A 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. Category: Feature | Tagged: , , , ,

KEK earthquake report

| 17 March 2011 As 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. Category: Feature | Tagged: , ,

FALC discusses future programmes in particle physics

| 10 March 2011 Representatives of particle physics funding agencies worldwide met at SLAC in January in an informal forum called FALC. This provided an opportunity to jointly discuss the worldwide program and plans in particle physics on the eve of the much anticipated next data run at the CERN Large Hadron Collider.

Many small klystrons for operability and flexibility

| 10 February 2011 Scientists at KEK in Japan are currently developing a 'distributed radiofrequency system' for delivering radiofrequency power to the ILC accelerating cavities. An alternative solution to the 'klystron cluster scheme', this powering method accommodates the ILC’s new one-tunnel design. Category: Around the World | Tagged: , , , , , ,

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 0.8×10^10. 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.

ILC and Super KEKB

| 18 November 2010 Even though additional funds are needed to complete the Super KEKB upgrade, th[e MEXT funding appropriation] signaled an essential go-ahead for the project, clearing the way for the ILC. Category: Research Director's Report | Tagged: , , , ,

“Set it and forget it!”

and | 28 October 2010 Fermilab and KEK scientists recently hooked up a new cavity tuning system to the various cavities in the so-called cavity-tuner zoo at KEK. This zoo, comprising eight superconducting radiofrequency cavities fabricated by four different vendors from three different regions, was the testing ground for a new development in what is called Lorentz force detuning (LFD) compensation.
