New CALICE calorimeter sees beam

| 31 May 2018 Particle physics will always need calorimeters, so particle physicists are always trying to optimise, tweak and update their calorimeter systems for the best possible measurements. The CALICE collaboration plays a leading role in this, and their most recent prototype for a hadronic calorimeter has just been completed and is now at CERN for a round of tests in the test beam.

Gearing up to final form

| 14 December 2017 Sometimes a neat line of dots on a computer screen can stand for that moment when it all comes together. A reward for years of hard work, many meetings, lots of travel and nights spent in test beam huts. At least that’s the case for a team of physicists and engineers who have spent the last years designing and testing detector components for a future linear-collider detector, the Silicon-Tungsten electromagnetic calorimeter or SiW-ECAL. During a recent test campaign at the German research lab DESY the developers came together to probe their latest detector design together with the latest sensors and all components that have been developed over the last years.

From metal sheet to particle accelerator (part 3 of 3)

| 12 May 2016 If you're an electron, a ride in a cavity is pretty much the coolest thing that can happen to you. If you're an accelerator and you need huge numbers of cavities you better make sure they're all of outstanding quality – which is what the X-ray free-electron laser European XFEL under construction in Hamburg has just finished. In a series first published in DESY inForm, we look at how a niobium sheet turns into a curvy beauty. Part three describes how they make their way from test benches into the cryomodules and, finally, into the tunnel. Category: Around the World | Tagged: , , , , , , ,

The European XFEL – helping pave the way for the ILC

| 11 June 2015 The European XFEL at DESY, Germany, will be a brilliant light source for a broad range of fundamental research in all areas of science – but it is also the first great mass production of the so-called TESLA technology. The ILC community is thus watching the construction of the European XFEL very closely. Category: Around the World | Tagged: , , , , , , , ,

Light as a feather

| 8 December 2011 A group of European physicists, the PLUME collaboration, aims to prototype an ultra-light device intended to equip one of the thinnest and lightest elements at the inner heart of the ILC detectors: the vertex detector. At CERN one month ago, a full-scale prototype equipped with CMOS pixel sensors was successfully tested in beam. Category: Feature | 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: , , , , , , , , , ,

LAL inaugurates calorimeter assembly hall

24 March 2011 Members of French teams who work on the SiW electromagnetic calorimeter prototype inaugurated the brand new LAL assembly hall on 14 March. Also shown are various members of laboratory directorates. Category: Image of the week | Tagged: , , ,

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.
