Tevatron sets new initial luminosity record

The Tevatron broke Fermilab’s initial luminosity record on Thursday, April 28, when store number 8700 achieved an average initial luminosity of 405.25 µb-1/s.

Then on Friday, April 29, an even higher average initial luminosity value of 416.61 µb-1/s was achieved by store number 8701.

These stores broke our previous record of 402.4 µb-1/s, which was set about a year ago, on April 16, 2010.

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