About the Collider-Accelerator Department

The mission of the Collider-Accelerator Department is to develop, improve and operate the suite of particle / heavy ion accelerators used to carry out the program of accelerator-based experiments at BNL; to support the experimental program including design, construction and operation of the beam transports to the experiments plus support of detector and research needs of the experiments; to design and construct new accelerator facilities in support of the BNL and national missions. The C-A Department supports an international user community of over 1500 scientists. The department performs all these functions in an environmentally responsible and safe manner under a rigorous conduct of operations approach.


Relativistic Heavy Ion Collider (RHIC)
An accelerator in which two beams of ions or polarized protons are accelerated and then collide in two locations, in order to study the state of matter formed in the first microseconds of the universe and the spin structure of the proton.

Alternating Gradient Synchrotron (AGS)
The AGS is the final stage of the injector chain which accepts beam from the Booster and accelerates it to the minimum RHIC energy. The AGS then injects the beam into the two accelerator rings that comprise RHIC

Booster Accelerator
The Booster accepts ions from EBIS and protons from the LINAC, and accelerates the beam to the minimum AGS energy before injecting it into the AGS. The Booster also supplies beam to the NASA Space Radiation Laboratory (NSRL).

Fed by either a polarized or a high-intensity proton source, the linear accelerator (Linac) supplies proton beams to the Booster for RHIC and NSRL, and to the production of medical isotopes at the Brookhaven Linac Isotope Producer (BLIP) facility.

Electron Beam Ion Source (EBIS)
EBIS creates ion beams from the lightest to the heaviest elements and, after acceleration in a small ion Linac, sends them into the Booster. The ions from EBIS are used either in RHIC or NSRL.

Tandem Van de Graaff
The Tandem Van de Graaff electrostatic accelerators supply a wide range of ion beams for radiation testing of electronic components and for manufacturing of industrial items.

Accelerator Test Facility (ATF)
The ATF provides a very high brightness electron beam to four beam lines, synchronized with high-power lasers, for the advancement of accelerator technologies and with a view to develop smaller machines and more cost-effective methods of particle acceleration.

For Users and Visitors

Visitors, please note:

All visitors who are not U.S. citizens must complete a Guest Registration prior to arrival at Brookhaven National Laboratory (in some cases 90 days in advance).

DOE, Office of Science One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
