This Small Business Innovation Research Phase I project will develop the Inductive Plasma Centrifuge (IPC) concept, a novel, high throughput approach for separating elements of different atomic weights. Mass based separation, ranging from the separation of heavy metal contaminated wastes to medical isotopes, is an important problem encountered in environmental remediation activities and in industry. A cost effective, high mass throughput separation method is needed. Vacuum arc centrifuges, studied for medical isotope separation, are limited by low mass throughput and high energy consumption, while gas centrifuges have limited rotation velocities and small separative powers. The objective of the proposed effort is to determine the feasibility of the IPC concept to overcome these limitations. This objective will be addressed in Phase I by performing three tasks: (1) design and assemble a small-scale IPC experiment; (2) perform preliminary feasibility experiments at pressures of up to 1 torr in order to demonstrate rotation frequencies of at least 105 radians/sec, and (3) develop the conceptual design for a Phase II IPC laboratory prototype device. If successful, this work will form a firm basis for comprehensive feasibility demonstrations of the IPC concept in Phase II. This project is responsive to the 1994 Solicitation emphasis on National Critical Technologies in the areas of Materials Synthesis and Processing, and Pollution Minimization and Remediation.

这个小型企业创新研究第一阶段项目将开发感应等离子离心机(IPC)的概念，这是一种用于分离不同原子量的元素的新型高通量方法。从重金属污染废物的分离到医用同位素的分离，基于质量的分离是环境修复活动和工业中遇到的重要问题。需要一种具有成本效益、高质量吞吐量的分离方法。用于医用同位素分离的真空弧形离心机存在质量通量低、能耗高等缺点，而气体离心机转速有限、分离功率小。拟议工作的目标是确定IPC概念的可行性，以克服这些限制。这一目标将在第一阶段通过执行三项任务来实现：(1)设计和组装一个小规模的IPC实验；(2)在高达1托的压力下进行初步的可行性实验，以演示至少105弧度/秒的旋转频率；以及(3)为第二阶段的IPC实验室原型装置制定概念设计。如果成功，这项工作将为IPC概念在第二阶段的全面可行性论证奠定坚实的基础。该项目响应了1994年对材料合成和加工领域国家关键技术以及最大限度减少污染和补救的国家关键技术的征求意见。
