Brookhaven National Laboratory is proposing to add a Stretcher ring to increase the capacity and the quality of the experimental physics program at the AGS. At the present time a typical AGS cycle is about equally divided between the task of accelerating the beam to full energy and the task of distributing it on a 30 GeV flattop. The Stretcher, a 30 GeV dc storage ring, will take over from the AGS the distribution of the high energy beam with a continuous slow spill, and the AGS can then provide beam for the program at more than twice the present repetition rate. In this manner the average current delivered to the experimenters will be more than doubled, and the duty cycle of the spill will increase from the present optimum of about 40% to nearly 100%. The Stretcher proposal continues the gradual evolution of the AGS toward a high intensity hadron factory. At the present time the AGS provides about 1 ..mu..A average proton current. With the booster alone, now under construction, this is expected to increase to above 4 ..mu..A, and with the Stretcher to about 8-10 ..mu..A, an order of magnitude higher than now. 5 refs., 9 figs.
