Alpha Magnetic Spectrometer

• Description– The AMS-02 employs a unique, superconducting electromagnet (SFHe @

2deg K) to produce a strong, uniform magnetic field ( ~0.8 Tesla ) combined with a state-of-the-art precision spectrometer to search for anti-matter (anti-helium and anti-carbon), dark matter, dark energy and to understand Cosmic Ray propagation.

• Investigators:– The AMS team, led by Nobel laureate Prof. Samuel Ting/MIT, has

approximately 200 physicists from multiple countries participating.– USA sponsorship by the U.S. Department of Energy.– Flown under a NASA / DOE interagency agreement (9/95) for two flights:

Engineering Test on Shuttle (STS-91) and 3 yr Science Mission on ISS.– NASA/JSC Engineering Directorate is assigned Project Management and

Payload Integration.
