The B0 low-beta insertion design for the tevatron
The low design of the low-beta insertion installed at the B0 straight section of the Tevatron is presented. This design replaces two of the regular lattice quadrupoles with stronger, separately powered quadrupoles and adds an additional triplet in the free space on either side of the interaction point. By varying the four separate quadrupole circuits, and two trim quadrupole tuning circuits, it is possible to go smoothly from the normal, fixed-target configuration with US * = 75 m in each plane to the colliding-beam mode of operation with US * = 1 m in each plane, while maintaining a constant tune for the Tevatron. A detailed study of the low beta insertion for the B0 experimental area has been carried out and is described. The purpose of the study was to see if it is possible to turn on the insertion in a smooth and continuous manner and tune the insertion to a value of US * of less than one meter while maintaining the overall tune of the Tevatron at a constant value. This was found to be possible. An examination of chromaticity corrections for the Tevatron with the low beta insertion on in various configuration was also undertaken.
