After the refurbishment of the Cooling plants (see next article) and 5 weeks of intense re-commissioning work, last night the Tracker joined the MW Global Run at zero tesla. Here are 4 cosmic muon events. A few modules appear a bit noisy still, so…

A series of important milestones have been passed during the last 3 months. With the delivery of refurbished cooling systems, pixels and strip systems have been brought back into operation after long shutdowns. Pixels has been operating since…

In July of last year we successfully inserted the pixel detector inside CMS and successfully integrated and operated it with the rest of the CMS detector during the CRAFT run. Despite the excellent detector performance some problems arose after…

The last two weeks the Forward Pixels (FPIX) detectors were both reinstalled and successfully tested. This activity was very much interleaved with the re-alignment of the central beam pipe. Both activities took place in a fragile and confined…

Loic Quertenmont has produced a lot of very nice pictures of events in the 3.8T field. Enjoy the slideshow too...

March CERN Courier has a centre spread article on the Tracker with a cover picture.
