Referencing Dilution-Based Trace Humidity Generators to Primary Humidity Standards

June 1, 2001
Author(s)
Peter H. Huang, Gregory E. Scace, Joseph T. Hodges
We describe a technique for measuring the trace humidity level delivered by a permeationtube type moisture generator (PTMG). Amount fractions in the range 10 nmol/mol to 100 nmol/mol of H2O in N2 carrier gas were considered. The measurements are referenced

Experimental Upper Bound and Theoretical Expectations for Parity-Violating Neutron Spin Rotation in He-4

July 16, 2019
Author(s)
Jeffrey S. Nico, Hans P. Mumm, H E. Swanson, C. D. Bass, T. D. Bass, J M. Dawkins, J C. Horton, D Luo, William M. Snow, S. C. Walbridge, B. E. Crawford, K. F. Gan, A M. Micherdzinska, C. R. Huffer, D M. Markoff, Murad Sarsour, E I. Sharapov, V Zhumabekova, Blayne R. Heckel
Neutron spin rotation is expected from quark-quark weak interactions in the Standard Model, which induce weak interactions among nucleons that violate parity. We present the results from an experiment searching for the effect of parity violation via the
