The BNL Booster is a fast cycling accelerator designed to inject high intensity beams of protons and heavy ions into the AGS. In order to minimize the losses of these high intensity beams due to space charge effects, it is important to maximize the percentage of particles captured inside the rf bucket. Numerical simulation is the most reliable way to study this process. To this end, the computer code ESME from FERMILAB was adapted and modified over the past several months to be used at BNL as a design tool. In particular, it was used to study the physics of the capture process in the BNL Booster and its dependence on machine parameters. In this note, we give a brief description of the main equations governing particle motion used in ESME and a brief account of the major revisions that were made to improve the FERMILAB version of ESME. We then present preliminary results of our simulation studies for the proton rf capture in the BNL Booster and, finally, conclude by mentioning some of the additional revisions we plan to incorporate in the next series of studies.
