The HEB at flat top: Arranging for the HEB to collider beam transfer
The flat top for the High Energy Booster (HEB) is planned to last for only 6.5 seconds, yet during this time the beam must be made to: (1) have the correct central momentum; (2) have the correct bunch-to-bunch spacing; (3) have the correct central phase; and (4) have the correct momentum spread and longitudinal length. All of these attributes must match what the Collider expects or unwanted emittance growth will occur. This paper outlines the techniques necessary to achieve a proper HEB-to-Collider beam transfer within the 6.5 s time constraint. A novel means for cogging is proposed and evaluated. The hardware necessary to implement the beam manipulation and to achieve the four goals is specified, and tolerances on the hardware are evaluated.
