An eye on the pulse

| 6 December 2012 The technical prototype of the silicon-tungsten electromagnetic calorimeter, one of the calorimeter options for the ILC’s ILD detector, is about to spend its first weeks in a test beam at DESY. The team will test its performance under power-pulsed operation and take detector development one step further towards a real collider detector. Category: Around the World | Tagged: , , , , , , , ,

LAL inaugurates calorimeter assembly hall

XFEL coupler industrialisation at LAL

| 23 August 2007 During an XFEL (European X-ray laser facility) project meeting, on 2 July at DESY, the main European contributors discussed in-kind contributions for the project. The meeting attendees agreed that France would play a large role in the production of power couplers for the XFEL. The LAL coupler group, at Orsay, will therefore be responsible for following the coupler production, their commissioning and delivery to DESY. To accomplish these tasks, the lab is now pursuing a big effort focused on coupler industrialisation. “This effort will be an exemplary exercise for ILC couplers production,” said Alessandro Variola, head of the LAL group.

The power of X rays for the ILC

| 19 July 2007 Producing intense polarised positrons for the ILC is very challenging. Stability, energy, luminosity are the key words. Parallel to the baseline studies on a helical undulator-based source (see Newsline from 19 October 2006), other groups, like the laser group at LAL (IN2P3/CNRS), Orsay (France), pursue R&D on a Compton positron source. The Orsay team recently measured an unprecedented enhancement factor of the pulsed laser beam inside their Fabry-Perot cavity. They expect bigger factors in a few months.

Annual ILC software workshop reviews whole chain of data analysis

| 10 May 2007 Even the best detector will be useless without clever reconstruction algorithms and software. On 2-4 May 2007, the ILC Software Workshop was held at LAL, Orsay (France). The whole chain of data processing was reviewed there: software framework and tools, algorithms and physics results. At the end of the workshop, DESY physicist Ties Behnke summarised that significant progress has been achieved over the past year and important performance milestones are close to being reached, even though the community is still small. Cambridge physicist Mark Thomson, finished his contribution declaring he was now convinced that Particle Flow Algorithm (PFA) can meet the ILC performance goals at 500 GeV and 1 TeV.
