Conservation and restoration of a particle accelerator Cockcroft-Walton*, located outside the cloister of the National Museum of Natural History and Science, in Lisbon, composed of various elements and materials, including different metal alloys, ceramics and paint coatings.
* Accelerator developed by the physicists John D. Cockcroft and Ernest T. S. Walton [1927], from the University of Cambridge (United Kingdom), awarded with the Nobel Prize in Physics [1951], because they have managed to accomplish, with this device, the first artificially induced nuclear reaction.
