Updating a turnkey cloud chamber for outreach and education activities

Since 2013, students at Siena College have worked to modify designs, found online, for what we refer to as "turnkey cloud chambers". These cloud chambers do not need dry ice, instead relying on Peltier thermocoolers to create the necessary temperature gradient. The cost of parts is around $150 and the group has run multiple workshops for local high school teachers showing them how to build their own. Siena uses these for outreach activities and as demos in the classroom. However, some components from the original design are no longer available. In this poster, we present our efforts to upgrade the design to use currently available components and modify the 3D printed support mechanisms, while improving the overall performance of the device.
