Happy birthday to us! Today is #Fermilabs50th!
We’ve come a long way! Tomorrow Fermilab celebrates its 50th birthday. We’re looking forward to the next 50 years of discovery and innovation.

Born at @infn_insights in Italy and refurbished at @cern, the enormous ICARUS neutrino hunter will make its way to Fermilab this summer! ICARUS is the largest detector of its kind, and it will become an integral part of neutrino research in the US. You can follow its journey with #IcarusTrip and at IcarusTrip.fnal.gov.

Today from 5-7 pm we are hosting a free reception for all. Come see the new art exhibit featuring the brilliant work of the lab's artist from 1967 to 1998, Angela Gonzales.
Technicians from @cern and @infn_insights recently converged at Fermilab to help prepare the ICARUS detector's future home.

#ThrowbackThursday to May 11, 1974, when Fermilab was named Fermilab! This photo shows the dedication ceremony, which took place in the horseshoe in front of Wilson Hall.

We’re turning 50 on June 15. Between now and then, we’re sharing 50 Fermilab discoveries and innovations! Today is our first milestone: when Fermilab's DONUT experiment discovered the tau neutrino.

On July 21, 2000, Fermilab announced the first direct evidence for a particle called the tau neutrino, the third kind of neutrino known to physicists. It had been hypothesized but never directly observed until the 2000 discovery, which was made by the DONUT (Direct Observation of the Nu Tau) experiment at Fermilab. The other two types, the electron neutrino and the muon neutrino, had been discovered in 1956 and 1962, respectively.

See all 50 milestones as they are released at the link in our profile - and let us know your favorite Fermilab discoveries and innovations!

#TBT to the Cockcroft Walton preaccelerator that used to be at the start of Fermilab's accelerator chain. We use different technology now: radio-frequency quadrupoles.
