200-GeV ISA with room temperature magnets

Abstract

A conceptual design study of 200-GeV proton intersecting storage accelerators with room temperature magnets is presented. The key to this study was the desire to keep the electric power consumption to an acceptable level (40 MW). The design has been optimized by choosing small"gap {4 cm) aluminum coil dipolee operating at about 15 kG. The luminosity of this machine is 32 -2 -1 limited to about 10 cm sec by transverse space-charge effects. An order of magnitude higher luminosities can be obtained by adding a booster of modest cost. A novel vacuum system using distributed Ti-sublimation pumps results in considerable savings. A cost comparison with a high-luminosity superconducting machine is given.

Proposal for construction of a proton--proton storage accelerator facility (Isabelle)

“…This high value can be obtained * by exploiting low-beta insertions, head-on (or small angle), collisions of the protons and, especially, the small emittance and high phase-space density of the AGS at Brookhaven. An informative expression for the optimum luminosity of proton storage rings has been derived by Keil,1 which is obtained by adjusting the amplitude function at the crossing point to the value i p i…”
