### Description

The SuperNEMO experiment aims to search for neutrinoless double beta decay. If observed, this would show that the neutrino is its own antiparticle and be the first evidence for total lepton number violation. With 100 kg of source, a half-life sensitivity of order $10^{26}$ years (effective neutrino mass sensitivity down to 50 meV) can be achieved. The experimental techniques are similar to the predecessor NEMO-3 experiment, with a tracker-calorimeter setup. Decay electrons from a source foil pass through a magnetised tracker, aiding in particle identification, and the calorimeter measures their energy. The setup is able to measure the angular distribution of the decay products, which can aid in determining the underlying physical process behind the lepton number violation if observed. The unique design with separation of source and detector also allows the study of different isotopes concurrently. To prove the challenging radiopurity requirements of the experiment are achievable, a Demonstrator module is currently under construction and will start taking data next year. The current status of the Demonstrator production will be presented.
