About this detector

This is the full detector planned at the ESS in the future. It was not the subject of this project but we can look at it in comparison to the prototype. They are of similar sizes - the TPCs would both be able to fit on a desk, and made of similar materials (argon gas mixture). The key difference is all of the extra material around the TPC. We can see the rounded cube TPC in the centre, with a larger cube around it. This material around the TPC is called a "cosmic veto", and will massively reduce the cosmic muon radiation mentioned in the previous section (the most persisent background effect in this experiment that reduces the quality of our data). The detector will be detecting neutrons that have collided witha rotating tungsten target. This neutron beam is difficult to work with as neutrons have no charge so we cannot guide them with magnets like protons
