American
Crystallographic
Association
2
history

• The ACA was founded in 1950 through a merger of
  the American Society for X-Ray and Electron
  Diffraction (ASXRED) and Crystallographic Society
  of America (CSA).
• ACA is an affiliate member of the IUCr and
  adheres to the IUCr Scientific Freedom Policy and
  is a member of the American Institute of Physics.
• 1Martin Buerger, Crystallography in North America
  (1983) 154.

perhaps most important is that the interests of
the root societies in a journal devoted to
crystallography was the stimulus which eventually
launched the IUCr and Acta Crystallographica. 1

objective

• The objective of the ACA is to
• promote interactions among scientists who study
  the structure of matter
• advance experimental and computational aspects of
  crystallography and diffraction
• promote the study of the arrangements of atoms
  and molecules in matter and the nature of the
  forces that both control and result from them

5
organization

• The affairs of the organization are managed by
  members who volunteer their time in various
  groups
• The elected Council, consisting of President,
  Vice President, Past President, Treasurer,
  Secretary National Div. Representative
• Twelve Special Interest Groups that organize and
  run sessions at the Annual Meeting
• Four Standing Committees that act as liaisons to
  the community and the Council

6

  interested in the purposes of the association
• Total membership of the ACA is about 2,200
  scientists representing over 60 countries
• Five categories of membership Regular, Retired,
  Post-doc, Student, Corporate

  Crystallographic Association or Group will be
  invited to attend the annual meeting and the
  associated Council Meeting with partial financial
  support from ACA. The designated representative
  will also receive complimentary, individual
  membership in ACA and subscriptions to Acta E and
  Acta F. Each year, two graduate students and one
  first-year postdoctoral student will each be
  given a one-year complimentary membership and a
  waiver of registration fee at the annual meeting.
  A subscription to all electronic IUCr journals
  will be granted to one laboratory in the country,
  identified by the National Association or Group,
  for one year only.
• The complimentary memberships and waivers of
  registration fees are unrelated to the travel
  award program and will not be taken into
  consideration when applications for travel
  support are reviewed.

11
country membership

• Student Travel Support for Annual ACA Meeting
• A Student Travel Support Committee, composed of
  one representative of each Latin American Member
  Country, will be established annually. One duty
  of the committee will be to select three students
  from any Latin American Country to receive travel
  awards to attend the annual ACA Meeting. The
  review of applications and selection of awardees
  will be coordinated with the Student Travel Award
  program of the ACA.
• The three choices made by the Latin American
  Student Travel Support Committee will be
  guaranteed up to 2000/each in support.
  Additional awards to Latin American applicants
  will depend upon the ranking of applications made
  by the ACA Committee for Continuing Education.
  The ACA Council will make the final determination
  of who will receive these additional awards.
