An integrated tool for ion linac design

Abstract

Abstract The initial design phase of an ion linac's front end often requires the use of several software programs, each dedicated to a specific component. These components typically include the ion source, a low-energy beam transmission line (LEBT) equipped with electromagnets, a measurement station, and finally the Radio Frequency Quadrupole (RFQ). Unfortunately, many of the legacy and proven software tools in this field lack user-friendly GUIs and have significant learning curves. In this paper, we present a novel approach: a unified software solution that offers a cohesive GUI and integrates with existing legacy software. This single-software approach not only simplifies the design process but also significantly reduces the time required for design and optimization. Our method has been successfully applied to various design configurations, demonstrating its efficiency in both the learning and design phases, compared to the traditional multi-software approach. In addition, we present DemirciPRO as an illustrative implementation of our unified software approach. This software tool showcases real-world scenarios and comparisons drawn from an ongoing proton linac project. DemirciPRO offers a cohesive user interface for designing an ion source, a Low-Energy Beam Transport (LEBT) line, and, ultimately, a Radio-Frequency Quadrupole (RFQ). Each module is capable of utilizing the output from the preceding one along the beamline. Furthermore, it possesses the capability to trace the trajectories of beam particles through the LEBT line using relevant transport matrices and through the RFQ using the leap-frog method.
