A heavy-ion tracking system is being developed by the University of North Florida to support nuclear astrophysics research at the Superconducting Accelerator Laboratory of the Florida State University (FSU). The tracking system consists of two identical ion detectors and is modeled after a focal plane detector system implemented at the Fragment Mass Analyzer of the Argonne National Laboratory. In each detector, a thin plastic foil emits delta electrons when a heavy ion passes through it. The delta electrons are accelerated away from the foil toward an electron "mirror" which reflects the electrons toward a stack of micro channel-plate electron multipliers. The detector system will provide position and direction information on heavy ions incident at rates up to approximately one million per second. The system will be used to track ion species generated by the exotic(radioactive) beam facility, RESOLUT, at FSU. The initial goal of the RESOLUT research program is to study nuclear reactions that are important inmodels of stellar nova explosions. Undergraduate students will participate in all aspects of this project.

北佛罗里达大学正在开发一个重离子跟踪系统，以支持佛罗里达州立大学超导加速器实验室的核天体物理学研究。 跟踪系统由两个相同的离子探测器，并仿照焦平面探测器系统实施的碎片质量分析仪的阿贡国家实验室。 在每一个探测器中，当重离子通过一个薄的塑料箔时，它会发射出δ电子，δ电子被加速离开箔，射向一个电子“镜”，后者将电子反射到一堆微通道板电子倍增器上。探测器系统将提供以每秒约一百万次的速度入射的重离子的位置和方向信息。 该系统将被用来跟踪离子物种所产生的外来（放射性）束设施，RESOLUT，在FSU。 RESOLUT研究计划的最初目标是研究在恒星新星爆炸模型中很重要的核反应。 本科生将参与这个项目的各个方面。
