NEST (Noble Element Simulation Technique) is an unprecedented comprehensive, accurate, and precise simulation of the excitation, ionization, and corresponding scintillation and electroluminescence processes in liquid noble elements, useful for direct dark matter detectors, double beta decay searches, PET scans, and general radiation detection technology. NEST has been verified as robust against a long list of past experimental results. Read more on the About NEST page.
