15 October 2009What do you visualise when you are asked about a sensor? There are many sensors around us. For example, CCDs (Charge Coupled Device), which is the basis of today’s digital camera, and the technology for this year's Nobel Prize in Physics are also sensors. Thus, sensors are absolutely necessary devices for our daily life and also important technologies for the International Liner Collider. In the last years, many new sensors have been developed for the ILC, one of them being pixel sensors using Silicon-On-Insulator (SOI) technology for particle detectors, under development at KEK’s Detector Technology Project Office. This sensor is expected to serve as one of the alternatives for particle sensors used in such parts as the silicon vertex detector.

Barbara Warmbein | 20 March 2008Have you ever used a map to find an electron? Not possible, you say? Think again. Spell it slightly differently – MAPS – put it into an electromagnetic calorimeter, and you may well be able to track an electron in a calorimeter and see the single electrons in a particle shower. With a spatial granularity of 50 microns square– that's 50 thousandths of a millimetre – a potential sensor, called MAPS or monolithic active pixel sensor, for an ILC detector's digital electromagnetic calorimeter could be an efficient alternative to existing silicon technology. A UK-based group is currently evaluating how suitable this technology is for a calorimeter optimised for particle flow, with a view to seeing how efficient, reliable and cost-effective it is.

31 January 2008The sixth meeting of the Silicon tracking for the Linear Collider R&D Collaboration (SiLC) took place at the University degli Studi in Turin from 18 to 20 December 2007. The three-day meeting was attended by about 50 people and covered all the main topics of interest for this R&D.

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."

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.
