Mass spectrometric analyses of high performance polymers to assess radiopurity as ultra low background materials for rare event physics detectors
Jay W. Grate, Isaac J. Arnquist, Eric W. Hoppe +4
The mass concentrations of Th-232 and U-238 in several strong, unfilled, high performance polymers are reported as measures of their radiopurity. Highly radiopure polymers are requ…
Direct method for the quantitative analysis of surface contamination on ultra-low background materials from exposure to dust
M. L. di Vacri, I. J. Arnquist, S. Scorza +2
In this work we present a method for the direct determination of contaminant fallout rates on material surfaces from exposure to dust. Naturally occurring radionuclides K-40, Th-23…
Evaluation and mitigation of trace Pb contamination on copper surfaces
Raymond Bunker, Tsuguo Aramaki, Isaac Arnquist +5
Clean materials are required to construct and operate many low-background physics experiments. High-purity copper has found broad use because of its physical properties and availab…
