THE FIRST EVENT

July 21st, 2010

The permanent magnet catched the first particle. A muon passed through its magnetic field and crossed all AMS-02 tracker planes. Cosmic-rays data collection has started! The re-integration of the AMS-02 spectrometer is going ahead and is nearly complete. Meanwhile all the subsystems are again operational and the first cosmic rays are detected and recorded by the data acquisition. The reconfigured Silicon Tracker with its nine planes works well: in this computer reconstructed image you can see one of the first

SAVE THE DATE

July 4th, 2010

26 February 2011, 4:19 p.m. EST, the AMS02 launch target date. NASA has just announced the new shuttle’s flights manifest: the STS-133 mission will fly the first of November over the Space Shuttle Discovery; then it’s STS-134 turn with AMS02 on board of the Space Shuttle Endeavour. Both missions will  fly to the International Space Station. Then the shuttles’ career will come to an end after  thirty years of service. Follow the STS-134 launch countdown on our homepage!

IT’S TRACKER TIME

June 30th, 2010

The magnets swap has been completed and integration of the payloads on the Permanent Magnet is progressing regularly. After the installation of the ACC and the Tracker inner core, the integration team is perfectly on time. We are now working at the relocation of the Silicon Tracker planes, to match the Permanent Magnet configuration. The new Tracker support structures and all the elements needed for this operation are already at CERN. After the fit-check of new Tracker planes, the integration

SEQUENCE MATTERS

June 14th, 2010

The reintegration of each subdetector on the AMS  experiment – now in the permanent magnet configuration – must follow a precise sequence. First come the TTCS tubing, then the ACC, the Tracker, the  TAS, the Star Tracker, the  TRD with the  UTOF … and the sequence  goes on with the  TRDGAS, the  LUSS and  the TCS main radiators. In the meantime the Multy Layer Insulation (MLI), that will cover the entire experiment,  is being integrated separately. There are various reasons
