title: Evaluation and utilization of beam simulation codes for the SNS ion source and low energy beam transport development.
abstract: Beam simulation codes PBGUNS, SIMION, and LORENTZ-3D were evaluated by modeling the well-diagnosed SNS base line ion source and low energy beam transport (LEBT) system. Then, an investigation was conducted using these codes to assist our ion source and LEBT development effort which is directed at meeting the SNS operational and also the power-upgrade project goals. A high-efficiency H(-) extraction system as well as magnetic and electrostatic LEBT configurations capable of transporting up to 100 mA is studied using these simulation tools.
