Low radioactivity techniques for Large TPCs in rare event searches

Abstract

The investigation of rare phenomena requires an effective suppression of all the background components entangling the expected signal. This has compelled the development of a wide range of low radioactivity techniques and background mitigation strategies. Some examples of those applied to Large Time Projection Chambers (TPCs) will be discussed here, including the operation of experiments deep underground, the exhaustive control of material radiopurity and the implementation of discrimination techniques.
