I am currently reading Beamtimes and Lifetimes, Sharon Traweek’s excellent anthropological study of the culture at particle physics laboratories in the 1970s when I stumbled upon a remarkable fact. The event rate of particle colliders has increased by a factor of 10 million between the 70s and 2016.
According to this 1976 SLAC report , the Large Aperture Solenoid Spectrometer (LASS) could record 100 events every second. That certainly sounds like a lot, but by contrast, by 2016 the LHC was producing 1 billion proton collisions per second . That is 10 million times the rate as ~40 years ago (and at much higher energy) . That is remarkable!

 The caveat here is that these rates probably shouldn’t be compared apples-to-apples like this, since the LHC doesn’t record 1 billion events per second, and there are other complicated factors.
