PERC

 

In order to achieve even better sensitivity with experiments using cold neutrons the statistics has to be increased, i.e. the amount of available neutrons or decay products. This is the purpose of the PERC project. PERC will collect both the protons and electrons from neutron decay along an extended stretch of a beam of cold neutrons and will make them available for precision experiments. In the case of aSPECT this will improve the sensitivity from Δa/a=0.3% in standalone mode to Δa/a=0.05% using PERC
