Description
The LZ collaboration has concluded one of the most comprehensive and wide-ranging assay and cleanliness programmes to date for an experiment of its type. This included assays for fixed contaminants through gamma-ray and mass- spectrometry, assays for mobile contaminants through radon emanation and assays for surface contamination through a variety of (radio-metric and optical) techniques. The cleanliness programme has ensured the minimisation of any additional sources of contaminants other than those intrinsic to detector materials in the fabrication and assembly of the detector. This talk will review the overall assay and cleanliness efforts of the LZ collaboration which began back in 2013 and has included measurements of over well over 1000 individual items. We will present assays of raw materials and finalized components that highlights the success of commercial and collaboration manufacturing efforts.
