French Linear Collider community meets to reinforce links with world-wide partners

Marc Besancon (CEA/Irfu), Maxim Titov (CEA/Irfu), Marc Winter (CNRS/IN2P3, IPHC) | 9 January 2014 The French Linear collider community organised its second “Linear Collider days” last November. The highlights of the meetings, summarised here by three of the organisers, show the diversity of the fields addressed the community and its expertise. The days ended with a special session dedicated to country reports where accelerator and detector activities in different continents were reviewed in the context of their possible future cooperation with France. It served as one of the building blocks in constructing European ILC Community. Category: Around the World | Tagged: , , , , ,

November in Paris: ILC prepares for Horizon 2020

| 5 December 2013 At a meeting in France in November, ILC experts in both detector and accelerator technologies discussed project and funding opportunities for the upcoming EU Horizon2020 framework programme. LCC European Director Brian Foster also took the opportunity to visit the European-XFEL village at CEA in Saclay which has produced a cryomodule that exceeds ILC requirements.

Good signal, little noise

| 18 April 2013 A concept to save space and power for future particle detectors called power pulsing has recently been tested and proven to work on one of the possible calorimeter options for the future ILC detectors. The silicon-tungsten electromagnetic calorimeter prototype took data in test beam and magnet at the German lab DESY. The project is currently run by groups from France and Japan.

France, Japan and Korea cooperation in particle physics

Image: CNRS/Yannick Legré | 31 May 2012 For the first time, two internationally associated laboratories, the France-Korea Laboratory for Particle Physics and e-science and the France-Japan Particle Physics Laboratory (renamed Toshiko Yuasa Laboratory), jointly held their annual meeting, providing new opportunities for trilateral collaborations. More than 70 physicists gathered from 28-30 May at the Laboratoire de Physique Corpusculaire, in Clermont-Ferrand, France. Talks included overviews from the directors of KEK, KISTI, CEA/Irfu and CNRS/IN2P3 and a review of the latest results of the collaborative work on particle detector and accelerator R&D, astroparticle and neutrinos and grid computing.

Michel Davier receives 2010 André Lagarrigue Prize

28 April 2011 Michel Davier receives the 2010 André Lagarrigue Prize from Martial Ducloy, president of the French Physical Society, on 26 April at the Linear Accelerator Laboratory in Orsay, France. Category: Image of the week | Tagged: , ,

A laboratory without walls

and | 14 April 2011 The France-China Particle Physics Laboratory is a lab without walls, enabling Chinese and French particle and accelerator scientists to work together towards the new energy frontier with experiments such as the LHC and the ILC. Its fourth annual workshop took place in Shandong University, Jinan, China from 7 to 9 April 2011. Category: Around the World | Tagged: , , , , , , , , , ,

Particle night fever in Paris

| 5 August 2010 How do you gather 2,000 Parisians and tourists in the middle of summer to talk about particle physics during a whole night? Probably following this recipe: find a magic venue, invite fascinating speakers and well-known artists, explore the frontier between science and cinema and advertise, advertise, advertise. Well, at least this is how the "Nuit des particules" – Particle Night – organised on 27 July at the Grand Rex theatre in Paris by the International Conference on High Energy Physics (ICHEP2010) this year happened to be a success.

ECal: a piece of the jigsaw reaches a milestone

| 5 February 2009 Hundreds of millions of channels of electronics: this is about what the electromagnetic calorimeter (ECal) of the CALICE collaboration will have to design, process and analyse. The very high granularity of ILC detector’s future calorimeter will also be reflected in the ambitious first-stage electronics – or very-front-end electronics, which still needs to be designed. One part of the electronic jigsaw is the analogue-to-digital converter (ADC). At LPC, a CNRS/IN2P3 lab in Clermont-Ferrand, France, the latest ADC prototype fulfills the ILC requirements in terms of resolution, compactness, time of conversion and power consumption.

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.
