The ATLAS User Group shall be formed from the members of the nuclear physics, nuclear chemistry and atomic physics community who are past, present, or potential users of the ATLAS facility. Its purpose is to provide a mechanism whereby the ATLAS users may advise and exchange information with the ANL Physics Division Director on matters relating to the development and operation of the facility.

An Executive Committee will be chosen from the membership. Four non-ANL members will be elected to three-year terms by the membership at large, and one non-voting ANL liaison member will be appointed by the Physics Division Director. The Committee will choose its own Chairperson from among the voting members. To provide continuity, the Chairperson will serve an additional term, but not as Chairperson, if the Chairperson served the full term of office.

At least six months before the expiration of their term, the Committee shall appoint a Nominating Committee whose charge will be to propose a slate of at least 4 candidates for the 3 elected positions on the Executive Committee. Written nominations signed by at least 6 members of the User Group shall also be accepted. An election must be held before December 1 of the third year of the term of office. The term of the Executive Committee shall begin on February 1 following its election from the membership.

If a vacancy arises on the Executive Committee, the Chairperson shall appoint a member of the User Group to serve out the unexpired term. In the event that the Chairperson’s position becomes vacant, the members of the Committee shall appoint a new Chairperson, who will proceed as above.
