摘要

介绍了一种简单、紧凑、廉价的云室的设计，并展示了来自宇宙射线和放射性样品的粒子轨迹示例。通过在顶部使用一个简单的加热器和在底部使用珀尔帖模块，在云室中建立了温度梯度，从而无需使用干冰。云室使用几毫升异丙醇，开机几分钟后就开始显示粒子轨迹，无需任何干预即可运行两个多小时。云室是用现成的部件建造的，总成本约为 40 英镑。

Cloud chamber using Peltier cooling

The design of a simple, compact, inexpensive cloud chamber is described and examples of particle tracks from cosmic rays and a radioactive sample are shown. A temperature gradient is established in the chamber through the use of a simple heater at the top and Peltier modules at the base, eliminating the need for dry ice. Using a few millilitres of isopropyl alcohol it starts to show particle tracks a few minutes after being switched on and operates for over two hours without any intervention. The cloud chamber is constructed using components that can be readily obtained at a total cost of about £40.

期刊介绍： Physics Education seeks to serve the physics teaching community and we welcome contributions from teachers. We seek to support the teaching of physics to students aged 11 up to introductory undergraduate level. We aim to provide professional development and support for teachers of physics around the world by providing: a forum for practising teachers to make an active contribution to the physics teaching community; knowledge updates in physics, educational research and relevant wider curriculum developments; and strategies for teaching and classroom management that will engage and motivate students.
