Conductor from the Philips Million-Volt Accelerator, 1937.

This conductor is from the voltage doubler stack of the Philips Million-Volt Accelerator, installed at the Cavendish Laboratory, Cambridge, in 1937. Conductors like this one carry the electric current as it is increased by the stack. The stack generates the electric field used to accelerate particles such as protons and electrons during experiments using the accelerator.
