Doubling the PEP-II Luminosity in Simulation

PDF Version Also Available for Download.

Description

Simulations show that luminosity of the PEP-II B-factory can be doubled from its present peak value of 1 x 10{sup 34}cm{sup -2}s{sup -1}. The particle simulation code BBI developed for studying beam-beam interaction was used to perform the simulations. It was first found that the parasitic collisions significantly degrade the simulated luminosity as the beam currents are increased from 3A and 1.7A to 4A and 2.2A in the low and high energy rings, respectively. The effect of changes in various accelerator parameters on luminosity was then studied in detail from a rough starting point based on analytic estimates and in ... continued below

The effect of changes in various accelerator parameters on luminosity was then studied in detail from a rough starting point based on analytic estimates and in the process we systematically optimized the luminosity and showed that a luminosity of over 2 x 10{sup 34}cm{sup -2}s{sup -1} is achievable within feasible limits.
