HRIBF Users Group Charter


The Holifield Radioactive Ion Beam Facility (HRIBF) Users Group is an organization of scientists interested in the radioactive ion beam research and technical program at the HRIBF. The purposes of this group are as follows:

A) To provide a formal channel for the exchange of information between the HRIBF administration and the scientists who utilize this facility for research.

B) To provide a means for the inclusion of its members in specific projects connected with the development and operation of the facility and in the program of research.

Through a wide representation of scientists, the group will make known to the HRIBF administration the needs and desires of those scientists actively engaged in research projects. As one example of the relationship between the users community and the HRIBF administration, it is expected that some members of the Program Advisory Committee will be selected from candidates proposed by the Users Group.

1. Membership.

The membership of the Users Group is open to scientists interested in the HRIBF. Users will be practicing experimental and theoretical scientists working in any field of research for which the capabilities of the HRIBF are appropriate. Following the completion of an original membership list, new members will be added by action of the HRIBF Scientific Director upon receipt of a written request. Each member will need to renew, in writing or electronically, the membership every third year beginning with the year 1979.

2. Officers and Executive Committee.

The officers of the Users Group shall consist of a Chairperson, Chairperson-elect, Liaison Officer, and four other elected members. The Chairperson, Chairperson-elect, and four elected members will constitute the Executive Committee of the HRIBF Users Group. The Liaison Officer will be an ex-officio member of the Executive Committee.

A. Two new members of the Executive Committee shall be elected annually by members of the Users Group by written ballot, distributed prior to October 1 to the membership as of September 1, and shall take office on January 1 of the following year. A plurality of votes cast is sufficient for election. In case of a tie vote the elected member will be selected from the candidates of said tie vote, by vote of the Executive Committee. The term of office is three years. After the election, the then current members of the committee shall choose one of the current first-year or newly elected members to be Chairperson-elect.

B. The Chairperson-elect will succeed to the office of Chairperson at the end of one year.

C. The term of Chairperson of the Users Group is for a period of one year.

D. Current members of the Executive Committee may not be nominated for re-election. No more than two of the elected members of the Executive Committee may be from one institution.

E. A Liaison Officer of the Users Group is appointed by the HRIBF Scientific Director in consultation with the Chairperson and Chairperson-elect of the Users Group. It will be the duty of the Liaison Officer to act as secretary of the meetings, keep the minutes, maintain the membership list, request nominations, send and tally mail ballots, and generally serve as secretary to the Users Group. It is further the duty of the Liaison Officer to keep the Users Group informed of new developments at the HRIBF and other matters of interest to the Users by means of frequent newsletters. The Liaison Officer shall serve a period of two years and can be reappointed.

3. Meetings.

The HRIBF Users Group shall meet at least once each calendar year at a time and place designated by the Chairperson, upon advice of the Executive Committee. Notice of the meeting shall be sent to the members of the Users Group at least a month in advance and shall include the agenda for the meeting. The Secretary-Liaison Officer will prepare summaries of all meetings, which will be mailed to all members, arrange details of meetings, and perform other necessary work of the Committee.

4. Procedures

A. The Executive Committee may, on its own initiative, and shall, upon instruction of a majority of the members attending a general meeting, submit questions for consideration to the full membership. Results of the deliberations of the Users Group shall be communicated to the Scientific Director of the HRIBF.

B. The Executive Committee shall be responsible for forwarding to the HRIBF administration names of scientists recommended for selection as members of the Program Advisory Committee and other committees as requested.

C. The Executive Committee shall appoint a Nominating Committee consisting of five members of the Users Group, but not including any officers, who are charged with the duty of nominating a slate of candidates each year for two positions on the Executive Committee. The Nominating Committee may meet in person if it wishes or may transact its business by mail or by telephone. The Chairperson of the Nominating Committee will be designated by the Chairperson of the Users Group. Direct nominations from the membership can be made by a petition from at least ten members, sent to the Chairperson of the Executive Committee prior to September 15. It is desired that the membership of the Executive Committee will reflect the diverse areas of research conducted at the HRIBF.

D. In the event that a position on the Executive Committee be vacated prematurely, the Committee shall appoint a member of the Users Group to fill the unexpired term. If the vacated post should be that of Chairperson- elect, the Executive Committee shall appoint a new committee member; the newly completed Executive Committee will then elect a new Chairperson- elect from among the committee members serving in their first or second year.

5. Amendments.

This Charter may be amended by a written vote of the members. A proposed amendment shall be introduced at a general meeting. A two-thirds majority of the members voting are required for passage of the amendment. The vote must be taken within a month of the time the amendment was introduced.
