This is the entry to the internal area within the particle accelerator which contains the beamline. You won't want to go in, the blue light indicates that the area is flooded with x-rays — dangerous radiation. The synchrotron has multiple safety systems, people entering the linear accelerator must display the key to the camera, and return it to the storage unit when leaving (the red box below the phone). Only when all the keys are in place can the system be fired up.
