Piece by piece

| 6 September 2007 The 1200 parts started to arrive at Fermilab in June. When fully assembled, these many parts will make up the first cryomodule for International Linear Collider R&D in the United States. The ILC will ultimately require 1680 of these cooled modules that hold the superconducting cavities, maintaining a temperature only two degrees above absolute zero. This first US cryomodule -which will only be used for R&D purposes-represents a special collaboration between Fermilab and DESY. Category: Feature | Tagged: , ,

Live from the test beam: calorimetry rises from the ashes

| 30 August 2007 This summer, a stage was all the world for some of the men and women of the CALICE collaboration. For the first time, the full prototypes of the electromagnetic calorimeter, the hadronic calorimeter and the tailcatcher and muon tracker (designed and built by international collaborations and assembled in Paris, Hamburg and Northern Illinois respectively) played lead roles in the SPS test beam at CERN. In more than two months, the collaboration collected more than 100 million events, nearly 14 terabytes of data, thus not only testing their prototypes but also the data grid.

Mapping a magnet

| 26 July 2007 Three pairs of eyes cast one last look around the room. Have all scissors, ladders, metallic tables been removed? No pins or pens lying around anymore? Once the team is sure that nothing is left in the area, they close the security doors and give the go-ahead – the magnet that has been to space can be charged for the first time since its arrival at its new home in the DESY test beam. Before its field of 1 Tesla can bend the tracks of particles in a EUDET detector prototype, however, the scientists have to map the field very precisely. And they don't want steel-capped boots flying into the coil. Category: Feature | Tagged: , , ,

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.
