An AMS upgrade

The 200th spacewalk at the International Space Station (ISS) included a new installation on the Alpha Magnetic Spectrometer (AMS) – a particle-physics detector that was assembled at CERN.
On 12 May, Commander Peggy Whitson and Flight Engineer Jack Fischer of NASA conducted the four-hour spacewalk, while ESA astronaut Thomas Pesquet stayed inside the ISS to drive the station arm that positions the two astronauts.
One of their tasks involved replacing a cable with a bus terminator – a type of connector – to carry data between AMS and the space shuttle. During the spacewalk, the AMS team stationed at CERN in the experiment’s Payload and Operations Control Centre (POCC), were able to check that the bus terminator was properly functioning. This connection will be used from 2018, when a new thermal cooling system for the AMS silicon tracker is put into place. … (CERN)
