When I see a new accelerator in real life or on a picture, I always find it interesting to see how many thing I can recognize. In that way, I can also get a small first idea of how the accelerator is working. Here is a picture, I have taken of LEIR at CERNLEIR

Help me to be able to recognize even more stuff, than I can now(I will post a few answers myself)

  • One line description
