CALICE meeting in Korea

26 March 2009 This is the second report on the two detector meetings held in Korea in February, ILD and CALICE, this time focusing on the CALICE (Calorimeter for the linear collider experiment) collaboration spring meeting at Kyungpook National University in Daegu on 19 and 20 February. CALICE, launched in 2002, meets twice a year to discuss the R&D issues of calorimetry technologies and the large-scale test beam experiments, specifically in the recent meetings to prepare for the world’s first test on a digital hadron calorimeter.

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.

CALICE collaboration is connected

5 June 2008 Even if you don't want to step through new control room's swish sliding doors, you can have a look inside DESY's new feature because of its doors made of glass: it is a medium-sized room with some technical interior and an ILC colour scheme. There are two computer working stations, each with four monitors and a small conference table; on a big screen you see the pictures from three webcams; and three clocks hang on the wall, showing the local times of DESY/CERN in Hamburg/Geneva, Fermilab near Chicago and KEK near Tokyo.

From Fermilab Today: Fermilab welcomes CALICE to Test Beam facility

8 May 2008 One of Fermilab's most distinct buildings now has a new resident. Last month, members of the CALICE collaboration moved their calorimeters into the newly renovated Meson Test Beam Facility. They will test the calorimeters with low- and high-energy particle beams during the next two years. Category: Feature | Tagged: , ,

CALICE gathers forces to design the calorimeters of the future

| 27 September 2007 The CALICE (Calorimeter for Linear Collider Experiment) collaboration is growing and anticipating the future of ILC calorimeters. The members not only prepare test-beams for the current generation of calorimeter prototypes, but they also prepare the future design of ILC sub-detectors. A record number of 72 CALICE members reviewed and discussed all these aspects two weeks ago in Prague during a collaboration meeting. 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.

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.

Fermilab users conduct ILC detector beam test

| 29 March 2007 Peeling paint? Leaky roof? No problem. Say the words “test beam facility” to a physicist, and the opportunity to collect real physics data will wash away any aesthetic issues. Literally. Category: Feature | Tagged: , , , ,

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.

Review of the French ILC Detector R&D

| 26 January 2006 The French ILC community held a SOCLE meeting (Seminar Oriented towards a Contribution to an Electron Linear Collider) in Lyon on 12-13 January 2006. More than 70 participants attended a review of the ongoing ILC detector R&D effort in CNRS/IN2P3 and CEA/DAPNIA laboratories. Future prospects and organisation aspects were discussed. Software tools dedicated to physics analyses and detector optimisation were also debated, in preparation for the Detector Conceptual Report, which will be delivered to the GDE by the end of 2006.
