It has to be an oscilloscope! This is a machine that shows electrical signals as lines on a screen. It helps me quickly spot any problems with a circuit and makes it easy to understand what's happening inside the electronics I work on.
I’m an apprentice for the Science and Technology Facilities Council (STFC), based at the Rutherford Appleton Laboratory. I work with mechanical and electrical systems, as well as computers. I build and fix circuit boards and other electronics, to help scientists do research. At STFC we use big detectors, such as the ISIS Neutron and Muon Source, to help people study things at the level of atoms, from ancient artefacts to the ingredients in chocolate bars. It’s a bit like having a very powerful microscope!
