The final store is now circulating in the Tevatron. At breakfast, it was just below 100E30 luminosity units (per square centimeter per second

It varies, but generally only components in direct contact with the beam show measurable residual radioactivity, not tunnel walls or floor. For (at a guess) 99% of the components in the ring, the amount is mild

I've been hearing about the planned tours for a while. If there were a special tour that would have a bunch of my favorite people attending, I might be more interested in attending that than a generic one...
I bet the targets in fixed target experiments get a lot more activation.
Fun fact learned while browsing the FNAL web site: the LSND experiment at Los Alamos put nearly a gram of 800 MeV protons into its target during its run. I imagine the high intensity plans you all have will go even higher.
Well, not right NOW, because today that beam is shut off to change the polarity of the focusing horn. But when it turns on again, the Main Injector will be shooting neutrinos at the basement of the Soudan Mine.
Unless we were already shooting neutrinos at Soudan, before the polarity change. In which case, we will now be shooting antineutrinos at Soudan. I'm not keeping track.
Interesting that ~1,000 students received their PhDs for work done on the Tevatron. That's a lot of (ahem) inbreeding, isn't it? Or maybe the study options for particle physicists are somewhat limited...
The most important thing about all of this to me is simple: will you, and our other friends, continue to be employed at FermiLab? xoxo
I'm sure it's a sad day for you Bill. You've been part of something really amazing. I'm sure you have more amazing things ahead of you, but it's still sad to see something like this end.

I'm sorry, Star Trek is suing you for copyright infringement.
