ILC Project Tools: Implementing the ILC EDMS

| 5 July 2007 We are now undertaking an engineering design, and the EDMS will be a central global collaboration tool for carrying out this next phase. Category: Director's Corner | Tagged: ,

LCWS 2007 & ILC 2007

| 7 June 2007 Hamburg put on its best face to greet the more than 600 registered guests who arrived at DESY last week for the big annual ILC get-together. Category: Director's Corner | Tagged: , , , , , ,

Living the Standard Model and Beyond: DESY Theorist Peter Zerwas retires

| 31 May 2007 In a packed auditorium many of world's leading high-energy physics brains celebrated ‘one of the sculptors of the physics of the ILC which wouldn’t be doable without him’, said Rolf-Dieter Heuer, DESY, and ‘not just a colleague, more of a friend’, said Siegfried Bethke, Max Planck Institute for Physics. Last Tuesday, a day before the start of the ILC / LCWS 07 symposium, they had gathered for a colloquium in honour of theorist Peter Zerwas, who is retiring at the age of 65, ‘after more than 250 publications, 12000 citations and certainly many more to come’, said Albrecht Wagner, DESY Director-General.

How a calorimeter could save your life

| 19 April 2007 Not many people see an immediate connection between exploring the origins of the Universe and finding cancer cells. Nicola d'Ascenzo and his colleagues sure do. In their work to test photo sensors as potential candidates for an ILC hadronic calorimeter they have come across a sensor that could be extremely interesting for positron emission tomography or PET, an imaging techniques that identifies cancerous cells in a body by detecting emitted gamma rays.

Test Beam Encounters: ECal meets HCal

| 29 March 2007 When scientists take their detector prototypes to a test beam they enter a parallel world. Many basic needs are put on hold - the need for sunlight, regular meals or eight hours of sleep, for example. What counts is the beam time: you have three days, weeks or months to test your equipment, and you have to make the best of it because you might not get another chance. A team from Japan and Korea have just reached the halfway point of their time in the DESY test beam, calibrating, checking and recording data with their electromagnetic calorimeter prototype.

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.

Testing, Testing

| 1 March 2007 Module 6 has had a bit of a break since we last reported on its progress (NewsLine 11 May 2006 and NewsLine 15 June 2006). It spent the last few months in DESY’s new module test stand in a brand-new building – as sparkling as new buildings in research centres get – and hasn’t been idle. Several cooling cycles and all sorts of tests over several months made sure that its creators knew the exact behaviour of all cavities, cables and couplers, the slow and fast tuners and the magnet.

Argonne-Fermilab BCP System Coming Together

| 4 January 2007 To make the superconducting cavities for the ILC sparkle, they must undergo a series of surface treatments to make them as clean and pure as possible – a necessity for achieving high accelerating gradients. Electropolishing and Buffered Chemical Polishing, the two types of chemical treatments required for the cavities, are not simple tasks. They involve tricky chemicals and a detailed recipe for producing the best cavities possible. Category: Feature | Tagged: , , , , , , ,

Unprecedented: 13.1 nm for FLASH!

4 May 2006 When Albrecht Wagner, Chairman of the DESY Directorate, opened his mailbox in the morning of 27 April and found an email about FLASH’s 13.1-nm success, he replied immediately: "This is exciting and fantastic news! Congratulations to the entire team!" FLASH, DESY’s pilot facility for the future European XFEL, produced the shortest wavelength yet. This success was celebrated with a party in DESY’s accelerator control room the night before at 22:10 h. Already after three hours, when the superconducting TESLA Test Facility Linac, equipped with five accelerator modules, reached the designated energy of 700 MeV, the electron bunches that traversed the undulator emitted laser flashes with a wavelength of only 13.1 nm (there’s a plot from the logbook for those who don’t believe it). This is an important step on the way to reach the design value of 6 nm planned for the FLASH facility. With the sixth module which will be installed in the second quarter of 2007, it will be possible to accelerate the electron bunches to 1 GeV and to generate wavelengths of 6 nm.

Fermilab Cools First TESLA Cavity from DESY

| 16 February 2006 On Monday, 6 February, a team of cryogenic engineers and accelerator physicists at Fermilab successfully cooled the first TESLA 9-cell 1.3 GHz cavity to 4.5 K (Kelvin) in the ILC Test Area in the Meson Detector Building (ILCTA-MDB). Travelling to Hamburg, Germany, Fermilab personnel assisted DESY in preparing the "ILC-like" cavity, called Capture Cavity II (CCII), and shipped it to its current home in Batavia, Illinois in August 2005.
