Abstract:
A collimation system for the Main Injector is described. It employs a primary-secondary collimation concept to localize the radiation induced by beam which fails to be captured and accelerated on Main Injector cycles which employ slip stacking. A primary collimator on the radial inside at MI230 imposes a momentum aperture which scatters beam which has not been sufficiently accelerated. A series of secondary collimators and masks localizes the beam loss and resulting radiation in order to reduce the activation of and radiation damage to accelerator components and minimize residual radiation. The hardware system is described and references are provided to the design calculations.
