At Brookhaven national laboratory we work mainly in the accumulator ring and transfer lines. Our group is part or the Collider Accelerator Division also in charge of RHIC and the AGS complex.  If you are looking for information in a particular topic you can contact the persons working on it. Here is a list of the accelerator physics group at BNL

The accumulator ring and transfer lines  are responsibility of Brookhaven National laboratory. Here is one of the older versions of the machine. Thanks to Jacques Negrin. The superconducting Linac would be at the left. The second target station is a future upgrade possibility but is not in currently in the baseline. Here you can also find all the released mechanical drawings and photo library
The ring, of 248m of perimeter has a 4-fold symetry. Every arc has four FODO cells and the straight sections are made up from doublet cells with three long ininterrupted straight sections. In the four straight sections we find (clockwise):  injection collimation extraction and the RF cavities. Diagnostics are provided all along the ring.
