The ATF Program Advisory Committee


The Accelerator Test Faility (ATF) Program Advisry Committee (APAC) is responsible for evaluating research proposals from ATF users and the scientific utilization of the ATF. It also provides advice and feedback on the developments and upgrades required to achieve and maintain the highest possible scientific and technological productivity at the facility. In keeping with this mandate, APAC will provide advice on the following topics:

  • User Experiement proposals approval based on scientific and/or technical merit, as appropriate.
  • Progress and performance of ongoing user experiments.
  • Scientific output and utilization of ATF as a DOE Office of Science User Facility.
  • Planning, development, and operation of ATF to meet long-term scientific and technology objects of the DOE Accelerator Stewardship mission.
  • Policies and precedures relevant to user access and utilization of ATF.

APAC members and a Chair are appointed by the ATF Director for five-year terms, with approximately one third of the members rotating off and being replaced every two years. APAC is composed of no more than ten scientists knowledgeable in the areas of research relevant to the ATF scientific programs. The APAC Chair may engage ad hoc consultants as needed to handle specific proposals falling outside the committee’s expertise. Such consultants may be engaged through either mail-in or in-person participation. Alternatively, the APAC Chair may designate a subpanel charged specifically with reviewing technical and/or commercial-use proposals.

APAC meets annually in conjunction with the ATF User Meeting. The ATF Director, in consultation with the APAC Chair, may call additional meetings as necessary. Before each meeting, the ATF Director provides a charge to the APAC and describes specific advice required from APAC.

APAC deliberations are confidential. The APAC Chair provides a confidential report of APAC’s findings and recommendations to the ATF Director shortly after each APAC meeting. Based on the APAC report, and in consultation with the APAC Chair, the ATF Director approves and implements each year’s user experimental program, updated facility policies, and facility recommendations. The report along with the facility implementation plan will be made available to Brookhaven’s senior laboratory management. In consultation with the APAC Chair, comments and recommendations that are relevant to the overall program will be forwarded to the Accelerator Stewardship Program Manager at DOE.
