Lesson-Learning from CMS

| 13 September 2007 Alain Hervé already has the experience of building two enormous detectors under his belt, and it looks like he is going to help in a third one. Technical coordinator at CERN of both L3 at LEP and CMS at the LHC, the Breton has now been called as an expert to help in the interaction region design, cavern and detector assembly planning for the ILC and its detectors. He is taking part in preparatory phone conferences for the IRENG workshop and co-convenes Work Group A that looks at how to design, install and open experiments.

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.

Getting the interaction point right

| 16 August 2007 Like the rest of society, the ILC community is split into two categories: the early risers and the night owls. Workshop organiser Andrei Seryi considers himself a night owl. Nevertheless he is up at 5 and in the lab at 6 am many days per week these weeks, holding phone meetings with the rest of the world. Some hundred specialists are already extremely busy preparing for the ILC interaction region engineering design workshop, or IRENG07, at SLAC in September. Their goal: to have all the facts together to take important decisions for the ILC’s interaction region. Category: Feature | Tagged: , , ,

High grades for HiGrade

| 2 August 2007 It’s the age of electronic mail, but in the last weeks Eckhard Elsen from DESY took several trips per day to his snail mail in-tray down the corridor because he was waiting for an important letter. Then finally a letter and an email arrived from Brussels saying that contract negotiations for a six-lab proposal managed by Elsen will start soon. ILC-HiGrade, or “International Linear Collider and High Gradient Superconducting RF-Cavities” is a proposal for the EU’s Seventh Framework Programme (FP7), which is asked to prepare for contract negotiations with a funding sum of up to five million Euros.

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: , , ,

EUDET’s Telescope

| 28 June 2007 Those scientists who develop detectors know a few magic words. Test beam is one, chip is one, DAQ is one. Telescope is another – and a prototype of one of these detector R&D ‘wands’ has just been tested in DESY’s 6-GeV electron beam as part of EUDET’s ‘Joint Research Activity 1’. EUDET is a Europe-funded and Europe-wide project for detector R&D, and one of its core activities is to test beam infrastructures – which include the telescope. It was also the first real test beam since the start of this EUDET activity. Category: Feature | Tagged: ,

German Research Minister launches XFEL

| 7 June 2007 On Tuesday 5 June, the German Federal Minister of Education and Research Annette Schavan officially launched the European X-ray laser facility XFEL. Using essentially the same uperconducting accelerator technology that is planned for the ILC, the 3.4-kilometre XFEL (for X-ray free-electron laser) will produce high-intensity ultra-short X-ray flashes with the properties of laser light. This will open up a whole range of new perspectives for fundamental research and for industrial users. Category: Around the World | 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.

Sports car treatment for cavities

| 24 May 2007 Challenges are all around for cavities that want to perform well. The material they are made of, the way they have been cleaned, they way they are shaped and they way their cells are welded together all influence the way the electrons fly through them. A process called hydroforming might be a means to tackle the last two threats, and a small team from DESY has just created the first all-niobium hydroformed nine-cell cavity.

Germany goes Tera

| 17 May 2007 All German universities and research institutes involved in the LHC and ILC have just pocketed 25 million Euros – and the prospect of a bright future at the Terascale. A DESY-driven funding proposal for the project ‘Helmholtz Alliance: Physics at the Terascale’ was approved by the senate of the Helmholtz Association on Tuesday this week. It bundles resources and expertise in German particle physics to allow scientists to play leading roles in particular in the LHC– and of course also the ILC. Category: Around the World | Tagged: , ,
