Collider ring particle loss tracking with SSCTRK.

摘要

The SSCTRK numerical simulation tracking code has been used to study the benefit of increasing the SSC dipole magnet aperture from 4 to 5 cm. This study has been carried out for both hypothetical highly corrected and plausibly corrected machines, the former having no systematic multipole errors and chromaticity identically zero. The choice of tune values, phase advance per cell, random multipole errors, systematic multipole errors and chromaticity (for the plausibly corrected machines), closed orbit error, the criterion for particle loss, etc. are set forth in detail. Runs of 10(sup 5) turns and 3 (times) 10(sup 6) turns are presented together with the approximate dynamic apertures they yield from their particle loss patterns.
