Barbara Warmbein | 19 July 2012Tracks show the paths of particles passing through the time projection chamber, the tracker prototype for the ILD detector, in a DESY test beam last week. Six brand-new readout modules of the Micromegas type - one possible module type for the final detector - were mounted to the TPC endplate and produced beautiful tracks both from cosmic and beam particles.

21 July 2011The PCMAG – the magnet of the large prototype time projection chamber – will travel from DESY in Germany all the way to KEK in Japan. Before the magnet can begin its journey it must be properly wrapped and lifted out of the DESY test beam facility. Have a save trip PCMAG!

17 February 2011The test beam season is about to start and the prototype of the ILD time projection chamber is being prepared for a round of new tests in the DESY testbeam facility - captured here by a professional photographer.

Barbara Warmbein | 13 November 2008The time projection chamber is part of the tracker system of a future ILD detector at the ILC and will one day reproduce highly precise tracks of the particles that passed through its gas. A plot of all the tracks leading to a workshop called ‘the tent’ on the DESY campus would make for an interesting event display: in the course of the last weeks many parts for the detector prototype arrived from destinations around the world, together with their experts. While field cage, cathode and module dummies came from Germany, the anode endplate travelled all the way from Cornell University in the States. France brought a Micromegas readout module, Belgium contributed the trigger logic and the Netherlands the beam trigger equipment for the coming test with cosmic rays or test beam.

Barbara Warmbein | 28 August 2008The international time projection chamber (TPC) team that works on R&D for future ILC detectors used to have a bit of a running gag. Somebody would proclaim that “the field cage will arrive next week” and everybody else would chuckle because week after week it didn’t arrive. Chuckling days are over now: after several years of planning the cage for the large TPC prototype, ordering it from industry, checking the quality, rejecting parts of the product and reordering, the nearly one-metre-long barrel with an inner diameter of 72 centimetres has finally arrived at DESY in Hamburg. First tests indicate that it will finally meet the team's high requirements.

Rika Takahashi | 24 January 2008From 7 to 11 January, the first school on the Time Projection Chamber (TPC) technology was held at the China Center for Advanced Science and Technology (CCAST) in Beijing. Over 50 students, young scientists and senior researchers from Asia and the rest of the world gathered to learn and discuss about TPC Technology for the International Linear Collider.

Perrine Royole-Degieux | 1 November 2007Digitisation - a key word that could lead to smaller and simpler detectors. Two weeks ago, at Saclay, France, the CEA Time Projection Chamber group of Paul Colas proved it could build a digital TPC for the ILC. A truly collaborative effort, this breakthrough could significantly reduce the cost and simplify the implementation of this sub-detector.

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.
