The Fermilab Collider Run I (1994–1996) experienced limitations in the Tevatron halo removal system that motivated upgrades for the halo removal system for the Collider Run II. The upgrade provided a new 2 stage collimator design, new designs for collimators and collimator motion control incorporating loss monitor and beam intensity feedback. A central process is used to coordinate the 12 collimator microprocessors that utilize local feedback to produce an automated halo removal system. The halo removal system and experiences for the Tevatron Collider Run II will be described. © 2003 American Institute of Physics
