Design status report on the Collider utility straight insertions

The lattice for the rings of the Superconducting Super Collider is divided into arcs, a FODO array of superconducting quadrupoles and dipoles; interaction regions, places where the beams are focused and brought into collision within physics detectors; and utility sections, places where injection, acceleration, abort, halo-scraping, and other control and diagnostic functions are performed. Recent modifications to the utility region design are reported here. Briefly these include lowering injection β-maxima by 40%; reducing the lengths and varieties of superconducting quadrupoles; improving conditions for injection matching; increasing abort admittance; mitigating component interferences; and identifying places for dampers and other beam instrumentation
