By making experiments ‘pre-calibrated’, consistency between HLSL production rates and experimental design is also preserved.However, initially this separation seems a little artificial, so we encourage new users to familiarize themselves with ACE by looking at the Quick Start Guide.Online Help For help and instructions regarding ACE, follow the Help links.By the time the cosmic ray cascade reaches the surface of Earth it is primarily composed of neutrons.When one of these particles strikes an atom it can dislodge one or more protons and/or neutrons from that atom, producing a different element or a different isotope of the original element.
