This is the moment when the object starts to talk to you and tells you its story. In this post we are going to share some of the pretty amazing stories which these X-Ray tubes have told us.
We started with some preliminary research using the internet and academic literature to find out more about what kind of X-Ray tubes we were dealing with, and to try to understand their functioning and to date them. We realised that the tubes represented four stages in the history of the manufacture and design of X-Ray tubes, from earlier examples to more modern models.
