The Design of the NAL Booster

Many types of injection systems have been studied extensively both at CERN and LRL. These studies were revived and extended at NAL during the latter half of 1967. Many people drawn from almost all accelerator laboratories both in the USA and in Europe contributed to the conceptual design. Although the whole question of booster type was reexamined from the beginning, the conclusions reached by this study group were in complete agreement with those reached in the LRL and CERN studies. Namely, that within the framework of existing technology, the most desirable type of injector is a fast-cycling synchrotron having a radius of a fraction of that of the main ring.
