How small can you go?

| 19 June 2014 The world’s smallest ever beam size of 55 nanometres was achieved by the ATF2 facility at KEK, reported Nobuhiro Terunuma at the AWLC workshop held at Fermilab. And what is more, the results are reproducible, which means that for the ILC, a recovery after a short break would be no issue. Category: Feature | Tagged: , , , , ,

ATF shuts down for summer

and | 5 June 2008 On the last day of May, ILC scientists and engineers enjoyed a barbecue, sushi and Ton-jiru miso soup with pork and vegetables in front of the ATF (Accelerator Test Facility at KEK) container. This gathering, called the ATF end-of-run party, has been a routine event for over ten years. Category: Feature | Tagged: ,

Hot topics in intensely cold Russia

| 26 April 2007 The baseline design for the International Linear Collider (ILC) positron source is based on multi-MeV photons that produce pairs in a metallic target. The photons are created by the main electron beam passing through a helical undulator. The conventional method, positron generation via pair production using an electron beam, which is used as the positron source in all existing accelerators in the world, is adopted however as an alternative technology in the Baseline Configuration Document (BCD).

STF – Getting ready for the experience

| 1 March 2007 An important prerequisite for building the ILC is to establish the design and manufacturing of major and vital components, such as cryomodules for the main linacs through realistic operating conditions. The Tesla Test Facility (FLASH) at DESY and Fermilab’s ILC Test Area have been pursued to play critical roles in the European and American regions to this end. KEK also aims to serve as an Asian regional center for the main linac technology, and their STF (Superconducting RF Test Facility) and R&D programs are a manifestation of its endeavour. Many members of STF from KEK are active members in the GDE and in close collaborative relationships with colleagues from DESY, INFN, Orsay, FNAL, JLab, Cornell and SLAC. Major laboratories from China, Korea, and India, have expressed their interests or have already begun interactions with the programme at STF in various forms also.

Finding a Common Language — Japan Society of Civil Engineers Announces Their ILC-Related Activities to the Press

| 25 January 2007 On 29 November last year, the Japan Society of Civil Engineers (JSCE) met with the press to explain the activities and present status of their ILC subcommittee, called the Technical Committee on Civil Engineering Issues for Linear Collider Project. The LC subcommittee was launched in June 2006 (See NewsLine 24 August 2006). One of the goals is an active collaboration between civil engineers and physicists to understand the civil engineering aspects for building the ILC in Japan. The subcommittee studies the necessary planning, geological survey, design, construction and maintenance phases for the project. The LC subcommittee is the first collaboration between physics and civil engineering in Japan, and it paves the way for future collaborative research or support.

First Japanese ILC Detector Workshop Held at KEK

| 18 January 2007 From 20 to 22 December 2006, the first Japanese "ILC Detector" Workshop took place at KEK. It was supported by the JSPS grant for Creative Scientific Research "Research and development of a novel detector system for the international linear collider," and about sixty participants - from undergraduate to senior researcher - from all over the country came to KEK. The main purpose of this workshop was to exchange news about the R&D status of ILC detectors and ideas on the Reference Design Report (RDR) and Detector Concept Report (DCR).

GDE Welcomes Two New Korean Members

| 27 April 2006 The Global Design Effort used to have two Korean members, one from Computing in High Energy and Nuclear Physics (CHEP) and the other from Pohang Accelerator Laboratory (PAL). But when a member from PAL moved to CHEP, the GDE recruited two new members, Jinhyuk Choi and Younguk Sohn of PAL, to restore balance. Category: Around the World | Tagged: ,

Kaoru Yokoya leads LC Office at KEK

and | 13 April 2006 As Fumihiko Takasaki steps down as the Asian Regional Director of the International Linear Collider to become the director of the Institute of Particle and Nuclear Studies at KEK, he also steps down as the head of the Linear Collider Promotion Office, or LC Office, at KEK. His successor at the LC Office is Kaoru Yokoya, an accelerator physicist who has been working for the linear collider for more than twenty years. Category: Around the World | Tagged:
