US - Sweden Cooperative Science: Atomic Physics Experimentswith Ion Storage Rings

该奖项将支持北卡罗来纳州立大学罗利分校的J. R. Mowat博士和瑞典斯德哥尔摩物理研究所的Reinhold Schuch博士在原子物理学方面的合作研究。Mowat博士将对离子存储环中电子冷却的模拟进行一系列实验，这是一项全新的原子物理研究技术。莫瓦特博士的研究是针对未来在美国进行的离子储存环的实验，但目前有必要与已经在建设中的欧洲项目保持密切联系。要充分发挥这些储存环的潜力，就需要电子冷却——一种提高储存束质量的技术——对离子也有效。离子存储环设计者需要对电子冷却进行真实的模拟，并且在模拟中必须仔细考虑某些原子物理效应。罗利的工作将集中在改进计算机模拟，模拟存储离子的电子冷却和电子-离子碰撞实验。在瑞典的第一个夏天（1989年）将用于测试实际的电子冷却装置，而第二个夏天（1990年）将用于用新完成的存储环进行原子物理实验。

This award will support collaborative research in atomic physics between Dr. J. R. Mowat, North Carolina State University at Raleigh and Dr. Reinhold Schuch, Research Institute of Physics, Stockholm, Sweden. Dr. Mowat will carry out a series of experiments on the simulation of electron cooling in the ion storage ring, which is a completely new technology for atomic physics research. Dr. Mowat's research is directed at experiments to be carried out on future ion storage rings in the US, but, for the time being, it is necessary to keep in close contact with the European projects which are already under construction. Full realization of the potential of these storage rings requires that electron cooling, a technique for enhancing the quality of stored beams, works for ions. Realistic simulations of electron cooling are needed by ion storage ring designers, and certain atomic physics effects must be carefully included in the simulations. The work in Raleigh will concentrate on the improvement of computer simulations which model electron cooling of stored ions and electron-ion collisions experiments. The first summer in Sweden (1989) will be spent testing the actual electron cooling device, while the second summer (1990) will be spent carrying out atomic physics experiments with the newly completed storage ring.
