Physics of AMS

• Search for Nuclear Antimatter with a 10-9
  sensitivity (anti-He,.,C)
• Search for supersymmetric Dark Matter (p-, e, g
  spectra )
• Astrophysics light isotopes, 2H, 3He, 9Be/10Be,
  B/C

AMS belts vs Van Allen belts

• Van Allen belts
• Low energy from 1 MeV to 100 MeV
• Contains e-, p
• High L-shells ? high altitude
• Life time O(years)
• Decays of neutrons produced in interactions of
  primary with the atmosphere (CRAND)
• Solar wind induced magnetic storms

11
AMS belts vs Van Allen belts

• AMS belts
• High energy from 1 GeV to 10 GeV
• Contains e, e-, p, 3He
• e over e- dominance
• Low L- shell ? low altitude
• Life time O(seconds)
• gt Secondary production from CR interaction
  with atmosphere
