The accelerator hall on top of the tunnel runs its entire length, making it one of the longest and straightest buildings in the world. It’s called the klystron gallery, after the machines that help the electrons in LCLS move through the accelerator. Without this apparatus, the electrons wouldn’t be organized enough to generate the X-rays scientists need for their experiments.
