Peter Kalmus and John Dowell, from the UK groups working on the project, were jointly awarded the 1988 Rutherford Medal and Prize from the Institute of Physics for their outstanding roles in the discovery of the W and Z particles.
In June 1984, Carlo Rubbia at the UA1 experiment expressed to the New York Times that evidence of the top quark "looks really good".
[3] The top quark was ultimately discovered in 1994–1995 by physicists at Fermilab with a mass near 175 GeV.
[4] The detector was a 6-chamber cylindrical assembly 5.8 m long and 2.3 m in diameter, the largest imaging drift chamber of its day.
Atoms in the argon-ethane gas mixture filling the chambers were ionised by the passage of charged particles.
