Description

When constructed, the LZ experiment will represent the most sensitive dark matter detector to date. In order to reach this sensitivity, the selection of materials used in construction is of paramount importance. The LZ collaboration has developed a wide ranging suite of materials screening instruments in both the US and the UK to characterise the intrinsic radioactivity of all components that will be used in the experiment. This assay programme includes screening for both fixed (U,Th,K) and mobile (Rn) contaminants in materials. It is through the variety of techniques used and the number of instruments available that we will be able to fully understand and minimise the radioactive backgrounds from materials in LZ. This talk will give an overview of the LZ screening facilities and will discuss recent assay results of some of the larger items (including the identification of the lowest background titanium assayed to date) that will be used in the construction of the LZ experiment.
