Thanks for this. I wrote that from experience at CERN from the
perspective of the beginning of LEP development. Unfortunately I didn't
make it any farther in what I was doing. I found CERN an absolutely
fascinating place to work coming as I did from the U.S.
I retired over 10 years ago and can barely understand what's happening
today. Good to know that only the names have changed (and the speeds).
