TOWARDS THE TWINS CHAMBERS SWITCHING

May 18th, 2010

Last weekend, at the Aachen RWTH I. Physikalisches Institute in Germany, the permanent magnet has been mounted inside the “flight spare” vacuum chamber. This Neodymium-Iron-Boron alloy cylinder, one meter high per one meter of diameter, has a magnetic field 3,000 times more intense than the magnetic field of Earth and is a veteran of space, since it has been flown in 1998 on the STS91 mission. Weighting 1.9 tons that become 2.9 tons once the vacuum chamber and the interface

WARMING UP

May 12th, 2010

After coming back home in the integration room building 867 at CERN, AMS will undergo magnets replacement. The vacuum chamber which contains the cryostat which maintains the magnet near the absolute zero is now warming up. Initially about 1,000 litres of superfluid Helium had to be removed. Very carefully, the SF Helium was warmed to 4 K and then pumped out while evaporating. During this step it is important to check that cryostat’s different parts have a temperature difference not exceeding

AMS LAUNCH POSTPONED

April 27th, 2010

It’s official. Following the decision to switch the AMS magnets, NASA has determined to move the STS-134 mission launch to mid November from the previous date of July 29th. The STS-133 flight, which was the last one to be manifested, will keep its September 16th launch date. The STS134 will then be the last shuttle mission, unless a new mission, STS-135, will be added to the manifest in 2011. Stay tuned!

AMS BACK TO CERN

April 26th, 2010

The first four trucks transporting the AMS-02 payload and its supporting hardware left ESTEC on April 22nd and arrived at CERN on April 26th. The fifth one, carrying the supporting gondola, is following. The detector is now back in the integration room, in building 867 on the CERN Prévessin side, where it will undergo a system test before starting the integration activities to replace the superconducting magnet with the permanent magnet.
