14 June 2007The calorimeters for the ILC detectors have to show excellent performance if researchers want to fully exploit the physics potential of the ILC. Many processes that are unique for the physics programme of the ILC are characterised by multiple-jet production that can be reconstructed by new calorimetry techniques to very high energies with unprecedented precision. The goal is to improve the jet energy resolution already achieved by a factor of two to fulfil the physics requirements the best possible way. Hence we need to develop these novel technologies and show that they work by ‘proof of principle’.

Barbara Warmbein | 19 April 2007Not 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.

Barbara Warmbein | 29 March 2007When 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.

Perrine Royole-Degieux | 1 February 2007At the heart of the massive ILC detector system, the vertex detector, a compact tracking device about the size of a wine bottle, surrounds the interaction region. This high-tech piece of equipment hosts about a billion pixels in total - equivalent to hundreds of the finest cameras. It works just like a 3-D camera because it measures the tracks of outgoing particles with micron precision. "Building and designing a vertex detector for the ILC is a real challenge," said Marc Winter, a physicist leading a micro-electronics group in IPHC, an IN2P3 Laboratory in Strasbourg, France. "This detector will reach fantastic performances, well beyond what was ever achieved so far."

Barry Barish | 2 November 2006Reaching the science goals for the ILC will require that both the collider performance and the capabilities of the detectors be consistent with the parameters set out by the ILCSC parameters group. For the ILC detectors, this will require improvements in both spatial and energy resolution.

9 March 2006If built, the International Linear Collider will hurl tiny electrons and positrons down 26 miles of accelerator, colliding the particles at the center in a microscopic explosion. But what good is it all if you can't see it happen?

Perrine Royole-Degieux | 26 January 2006The 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.
