“If someone asks me, “Is that the accelerator there?” I don’t simply say yes and leave it at that. I throw in some extras, for example, I say, ‘Well, that it just a part of it. The actual beam is roughly 25 feet underground. But to power the beam we use 240 klystrons. See those machines over there with the red cylinders? They are located above the beam in this shed which 2 miles long and actually the longest building in the world. In fact it is around 10 feet longer than the Hong Kong airport terminal! Any fascinating fact is great to share and gives visitors that wow factor, which guides enjoy as well.”
