ATLAS to install neutrino calorimeters
The ATLAS detector is currently the largest experiment on the CERN site, weighing over 7,000 tonnes, spanning 50 m across and almost 50 m long. It can detect nearly all particles produced in the record breaking high energy collisions provided by the LHC. These particles have strange names like the electron, proton, pion, Ξ(1530)3/2+, photon, friton, demi-semi-lepton and Boris. But there is a big problem, which becomes more pressing as we reach higher and higher energies, and that is the neutrino. This is a tiny, neutral, almost massless particle that was predicted in 1930, and it comes in different flavours (the most popular being mint.) The ATLAS Collaboration has an ambitious plan to extend the capabilities of its detector by being the first such general purpose detector to install neutrino calorimeters. At the moment a neutrino is seen as “missing transverse energy”, and that makes it really hard to find new particles.
