I was recently underground on a tour of the LHCb detector. It was the last one of the four main LHC detectors I hadn’t seen in person. I also got to see the old DELPHI detector which is still down there. I will post some pictures soon.
On my way down, I took a picture of one of the infamous iris scanners mentioned in Angels and Demons. In the book, someone at CERN is murdered and their eye taken in order to get through this security feature. In reality, a dead eye cannot be used with this technology.
Everyone who visits the underground areas at CERN is fascinated by this technology. I think CERN should put one of these scanners in the visitor’s center just for tourists.
