Omnibus is ominous

| 20 December 2007 Our plan this week was to make this issue of ILC NewsLine a thematic one, highlighting progress on Superconducting Radiofrequency R&D, the central technology for the International Linear Collider. It would have made a very nice final edition for this calendar year, but unfortunately new events that imperil the future course of the ILC must be addressed instead.

US-manufactured cavity achieves high gradient

| 6 December 2007 Turkey, stuffing and pumpkin pie – all things you might appreciate on Thanksgiving. ILC scientists in the United States had something extra to be thankful for this year. On 21 November, the day before the Thanksgiving holiday in the US, a superconducting cavity manufactured by Advanced Energy Systems in Medford, NY, reached a high gradient of 32.6 megavolts per metre (MV/m) at Jefferson Laboratory. “This is the first US-built ILC nine-cell cavity to reach a gradient close to the ILC specification,” said Rongli Geng, the lead scientist at JLab on the nine-cell high-gradient cavity processing R&D. JLab scientists are hopeful that the cavity, dubbed AES2, will reach an even higher gradient after further processing. Category: Around the World | Tagged: , , ,

Critical decisions

| 1 November 2007 Last week was an eventful week. The ALCPG07 and GDE meetings at Fermilab, attended by over 300 scientists and engineers, marked the completion of the ILC Reference Design Report and the beginning of the engineering design activities. The joint plenary session on the first day of the meeting featured a presentation (video and slides) by Dr. Raymond L. Orbach, Under Secretary for Science at the Department of Energy. He made a number of key points. He noted the importance of our recently released RDR in planning the future course of the ILC. He commented on the need to formalise the international ILC partnerships between interested governments. He issued a directive to proceed with the US funded ILC R&D through the DOE Critical Decision process. He stated the need for the Global Design Effort to take into account the constraints of obtaining government funding in our schedules for the ILC. Category: Director's Corner | Tagged: , , ,

Project X at Fermilab

| 20 September 2007 These days it seems that the questions I am asked most frequently are not about what gradient we will achieve for the ILC, not who will be the ILC Research Director, the next SLAC Director or the CERN Director General. Instead, I receive both genuine and rhetorical questions about Fermilab's proposed Project X. Category: Director's Corner | Tagged: , ,

Windy city prepares for ALCPG07

| 13 September 2007 Get ready for deep-dish pizza and hot dogs piled high with onions, peppers and a pickle because the 2007 American Linear Collider Physics Group and International Linear Collider Global Design Effort meetings are heading for the windy city. Fermilab, located just outside Chicago, Illinois, will host the joint ALCPG07 meeting on 22-26 October in a continuing series of workshops on the physics, detector and accelerator issues of the proposed ILC. Interested participants should register soon, as the deadline to book a hotel room is 21 September. Category: Feature | Tagged: , , ,

Texas team proposes new superconducting cavity design

30 August 2007 At Texas A&M University, a team led by Peter McIntyre has developed a new design for superconducting cavities for linear colliders, perhaps even the International Linear Collider. Their polyhedral cavity design, which is only in its beginning stages and requires a significant amount of R&D, could offer such benefits as increasing the accelerating gradient and making the cavities more cost-efficient.

Good vibrations at Fermilab

| 9 August 2007 Vibrations in the cryomodules in the International Linear Collider are actually not a good thing. The slightest disruption can throw off the alignment of the super sensitive beams and prevent them from colliding. The stringent beam dynamic requirements in the ILC therefore make vibration studies important, which is why Fermilab recently installed measuring devices called geophones in their Horizontal Test Stand. So for the team at Fermilab, detecting vibrations now, during an R&D phase, is actually a good thing because it means that they can learn how to minimise them in the actual machine when every collision counts.

University Profile: Northern Illinois University

| 12 July 2007 Amidst the corn fields in DeKalb Illinois, 65 miles to the west of Chicago, a group of 22 physicists and students, who are members of the Northern Illinois Center for Accelerator and Detector Development (NICADD) at Northern Illinois University, contribute to the International Linear Collider in more ways than one. From beam dynamics to calorimetry hardware to simulation software, the ILC group at NIU covers it all. Because the group consists of such a large number of undergraduate and graduate students, training the future generation of scientists – who may be running the actual ILC one day – is perhaps one of their largest contributions of all.

DOE and NSF Review US Detector R&D Programme

| 28 June 2007 The cacophonous tune of cicadas serenaded the physicists at last week’s Department of Energy and National Science Foundation review of the US Detector R&D Programme for the International Linear Collider. Harry Weerts, the High Energy Physics Director at Argonne National Laboratory, where the review took place, vividly remembered the last time the cicadas visited --17 years ago when another detector milestone was in the making. “I remember it well because we were commissioning the DZero detector at Fermilab,” he said. “I’m looking forward to the next time the cicadas come around and seeing what the world looks like then.” Category: Feature | Tagged: , , , , ,

DOE and NSF Review of the ILC-Americas Programme

| 10 May 2007 The second review of the US R&D programme for the International Linear Collider (ILC) by the Department of Energy (DOE) and the National Science Foundation (NSF) was held at Fermilab from 30 April to 2 May 2007. This meeting served as DOE and NSF's primary peer review of the US portion of ILC RD activities. Category: Director's Corner | Tagged: , , , , , ,
