The UA1 experiment (an abbreviation of Underground Area 1) was a
It was named as the first experiment in a CERN "Underground Area" (UA), i.e. located underground, outside of the two main CERN sites, at an interaction point on the SPS accelerator, which had been modified to operate as a collider. The UA1 central detector was crucial to understanding the complex topology of proton-antiproton collisions. It played a most important role in identifying a handful of W and Z particles among billions of collisions.[1]
After the discovery of the W and Z boson, the UA1 collaboration went on to search for the
The UA1 was a huge and complex detector for its day. It was designed as a general-purpose detector.[4] The detector was a 6-chamber cylindrical assembly 5.8 m long and 2.3 m in diameter, the largest imaging
The UA1 detector was conceived and designed in 1978/9, with the proposal submitted in mid-1978.[6]
Since the end of running, the magnet used in the UA1 experiment has been used for other high energy physics experiments, notably the NOMAD and T2K neutrino experiments.
