Before it started, the Tevatron collider at Fermilab (near Chicago in the USA) was the most powerful collider, I spent a substantial fraction of my career working at that machine.
Damned... Now I really feel old too... I started my career when the Tevatron was running....
PS: I hope you don't mind having me spamming the comments to your post :)
haha when I started my PhD, LEP was still running! (just. But still). But then I am old too :)
and please spam my posts, it is fun to see the different ways we explain. I am used to teach first year students more I think :)
The same holds for you. Feel free to spam my posts :)
