Tevatron sets new initial luminosity record

The Tevatron broke Fermilab’s initial luminosity record on Thursday, April 28. That afternoon, store number 8700 achieved an average initial luminosity of 405.25 µb^-1/s. This broke our previous record of 402.4 µb^-1/s, which was set on April 16, 2010.

The unit of measurement µb^-1/s is roughly equivalent to 70,000 proton-antiproton collisions per second.
