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 we have some more work to do, but our detector is operational again!

Here you can enjoy a full slide show of events (thanks to Loic Quertenmont)
