Japanese 9-cell SCRF cavity meets ILC specifications

Many small klystrons for operability and flexibility

16 Feb 2011

The design of the International Linear Collider has recently changed from featuring two tunnels to just one. This means many aspects of the tunnel design have to be re-thought -- including the distribution of the radiofrequency power, the acceleration technology of choice for the ILC's superconducting cavities. In addition to the klystron cluster scheme, the power-delivery system for radiofrequency cavities introduced in last week's ILC NewsLine, an alternative scheme is being developed at KEK, Japan.

Japanese 9-cell SCRF cavity meets ILC specifications

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 0.8×1010. 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.

The ILC-CLIC collaboration and technological challenges

Today's issue features a Director's Corner from Kaoru Yokoya, Global Design Effort Asian Regional Director.
In recent years, the collaboration between the ILC and CLIC communities has developed and evolved, and Barry Barish has reported on this collaboration in previous corners. Working groups on many R&D areas have been formed. Recently the Accelerator General Issues Group, which takes care of project strategy and planning, and the Detector Group have also formed. Last month in Geneva, we held our first ILC-CLIC joint meeting (IWLC10), as Peter Garbincius reported. ILC and CLIC are quite different in their ultimate target energies and in their fundamental acceleration mechanisms. Nonetheless, as electron-positron linear colliders they have many technological common areas. Under the tough situation of limited resources around the world, this collaboration is welcome and, actually, we have been producing good results.

Set it and forget it!"

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.

Start operation of the Small Electron Linear Accelerator for calibration of the Fluorescence Detector of the Telescope Array experiment
The Telescope Array (TA) experiment is a ultra-high energy cosmic rays (UHECRs) observation which is established in the desert area about 200 km far from Salt Lake City in Utah state, north U.S. We began the observation in April 2008. The UHECRs are the highest primary cosmic rays which have energy more than 1018 eV. However, we do not understand any fundamental features, for example the chemical composition, their generation and acceleration mechanism, and the theoretical flux limit (GZK-cutoff ).

Deepen the bonds: collaboration between Vietnam and KEK

26 Aug 2010

Vietnam and Japan have been nurturing cooperative relationship in many fields for many years. For the field of science and technology, both governments signed the Japan-Vietnam Science and Technology Co-operation Agreement to promote and deepen the co-operation in science and technology in 2006. Following year, Shinzo Abe, then Prime minister of Japan, proposed at the East Asia Summit (EAS) to launch a youth exchange initiative totaling 35 billion Yen over five years including the invitation to 6,000 young people from the member countries of ASEAN and EAS to Japan, which was accepted with great welcome. Now, these invitations are bringing many Vietnamese scientists to KEK.
Never lost in translation - A French scientist working at the ATF 11 Aug 2010
Every day, KEK welcomes scientists and students from around the world. ・・・Bambade, a specialist on machine-detector interface, has travelled to Japan many times as a part of the international team working at the Accelerator Test Facility (ATF). The ATF is a test accelerator focused on generating the super-low-emittance beam, one of the essential techniques to realise the next electron-positron linear collider. The team has already achieved the smallest emittance in the vertical dimension.
An advanced 2D detector for medical, materials and life sciences 10/07/14   
One of the Detector Technology Project (DTP) groups at KEK has developed
multi-purpose, two-dimensional detector called a gas electron multiplier (GEM) for use in small radiation-related experiments. The GEM’s good time- resolution has also given birth to a new field of radiography, called energy- selective radiography. Read here how GEM can play an important role in neutron science, medical applications, and more.


The neutron GEM detector enabled the two-dimensional imaging of metal content. Here the gold content of Euro coins (top) and a Japanese oval gold coin from Edo period (bottom) are shown in green.
