Abstract
As we move to an era where next generation ultra-low
background particle physics experiments begin to be designed and
constructed, the ability to assay materials with high sensitivity
and at speed with a variety of techniques will be key.
This paper describes the Mirion Technologies (Canberra) specialty
ultra-low background detectors installed and commissioned at the
Boulby Underground Laboratory between 2017 and 2021. The low
background levels of the detectors combine with low background
shielding and a radon-reduced dry nitrogen purge system to give
sensitivity approaching the best in the world without the need for
intricate shielding solutions.
For an optimised sample geometry, run for 100 d, it would be
possible to reach close to 10 μBq kg-1
(10-12 g/g) for background radionuclides of interest in
neutrinoless double-beta decay.
