A "delay line" has been proposed to be installed in the Blue ring of the Relativistic Heavy Ion Collider (RHIC) to accommodate collisions between asymmetric nuclei. The function of the "delay line" is to provide an additional path length of ∼ 15 cm to the circulating bunches in the Blue ring to synchronize collision with the lower speed beam bunches of the Yellow ring at the interaction points (IP's). The delay line can also be used in the proposed e-RHIC accelerator for the electron hadron collisions at various energies. This paper serves as a feasibility study to identify any problems whose solution may improve the function of the delay line. Since few solutions may be possible, in this paper we present the layout and the optics of the delay line for on one of these possible solutions and we will discuss the energy range that asymmetric collisions can be performed in the RHIC collider.
