Demonstrating the ILC final focus parameters

| 2 May 2013 A key feature of the ILC is that it is a single-pass machine. In contrast to a circular accelerator, where the beam goes around many times, the ILC beams pass through each accelerator element only once, including the interaction point. For the accelerator, this means that for each accelerating module, the machine must be very efficient at transferring wall power into the machine beam, with the added requirement that the final beam must emerge with very low emittance so that it can be focused to the very tiny beam spot required to achieve high luminosity. The ATF-2 at KEK is a special test beam line that has been built to demonstrate the ability to achieve ILC-like namometre beam spots and stabilise them. Recent tests have demonstrated beam spots that are within a factor of two of the ILC design and promise to improve in the future. Category: Director's Corner | Tagged: , , , ,

Final focus

| 21 March 2013 What makes the ILC beams far smaller than a human hair? A series of magnets referred to as the ‘final focus,’ designed to maximise chances of collision at the heart of the ILC detectors. Category: LCpedia | Tagged: , ,

Japanese diet members focus on ATF2

| 21 March 2013 Twelve members of the Japanese Federation of Diet members to promote the realisation of the ILC visited KEK on 4 and 18 March. They spent the longest time at ATF, KEK's test facility for the linear collider. They also toured KEKB, Belle, and the Photon Factory. Category: Image of the week | Tagged: , ,

TDR review season is underway

| 7 February 2013 The draft of the ILC Technical Design Report (TDR) was completed last November and submitted for review. On 13 and 14 December, the TDR underwent a technical review at KEK by an augmented ILCSC Program Advisory Committee. The review report endorses the technical design we have presented and recommends “no changes in the TDR.” The report does identify areas and items to address in the future.

ATF autumn run started: aiming for the beam size required for the ILC

| 25 October 2012 KEK's Accelerator Test facility (ATF) is up again after its summer shutdown. After several improvements to beams size monitors, multi-ole magnets and the organisation structure, the international team is looking forward to squeezing the beam size further and further towards the 37 nanometres required for the ILC.

Recovery from March 2011 earthquake at ATF, KEK

| 15 December 2011 Restoration of the Accelerator Test Facility is in its final stage at KEK, Japan, where the ATF2 project, the final focus test beam for ILC, is being conducted with an international collaboration. Category: Director's Corner | Tagged: , , , ,

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: , , , ,

Progress in the nanometre world

| 24 February 2011 Two periods dedicated to beam tuning and beam size studies at KEK's Accelerator Test Facility ATF2, built to test the ILC's final focus system, have brought researchers a step closer to achieving the ILC's demanding beam parameters. Executive Committee member Toshiaki Tauchi reports on the studies. Category: Director's Corner | Tagged: , , , ,

From KEK Highlights: Never lost in translation

12 August 2010 Every day, KEK welcomes scientists and students from around the world. Some of them come here as collaborators who work on the international projects and programmes using cutting-edge facilities at KEK. Some visit as users who wish to use the beamlines at the Photon Factory to look into the smallest worlds. Many graduate students will write up their hard work here into their thesis. Many of them stay only days or weeks, but some of them stay longer to concentrate on the R&D for months or even years, like Dr. Philip Bambade from LAL in Orsay, France.

A young female expert on beam size

| 3 June 2010 In June, a lot of Chinese students graduate from different schools. Sha Bai, a PhD student from the Institute of High Energy Physics (IHEP), is one of them. “I enjoy my research work very much. I like ATF2, ILC and CLIC a lot,” said Bai, who just received her doctoral degree in June 2010 working on ATF2 (Accelerator Test Facility 2) at KEK in Japan, with the goal to reach 37-nanometre vertical beam size at the interaction point, both in beam optics and experimental work.
