Design study of PAL-stretcher ring

We completed the commissioning of the PLS 2-GeV electron linac, which is a full energy injector for the storage ring of the Pohang Light Source, in June 1994. The prime mission for providing beams to the storage ring requires a few minutes for each injection, and a few times per day when the PLS is under normal operation. Hence, we can utilize high energy electron beams for the electron scattering experiments. In order to produce high current and high duty factor beams, the design of a pulse stretcher ring is underway. This paper presents the result of the design study as well as the experimental plan.
