    • Co-Chairs of the SSRL Proposal Review Panel (PRP)
    • Chair of the Structural Molecular Biology Advisory Committee (SMBAC)
    • Chair and Past Chair of the SSRL Users' Executive Committee (SSRL UEC)
  • SAC members are appointed by the SSRL Director for 3-year terms, with one third of the members rotating off and being replaced every year
