The detector concept integrates a segmented 3He ionization chamber with the position sensitive, charged particle collection methods of a MicroMegas detector. Neutron absorption on the helium produces protons and tritons that ionize the fill gas. The charge is amplified in the field region around a wire mesh and subsequently detected in current mode by wire strips mounted on a substrate. One module consisting of a high-voltage plate, a field-shaping high-voltage plate, a grid and wire strips defines a detection region. For 100 % efficiency, detector modules are consecutively placed along the beam axis. Analysis over several regions with alternating wire strip orientation provides a two-dimensional beam profile. By using 3He, a 1/v absorption gas, each axial region captures neutrons of a different energy range, providing an energy-sensitive detection scheme especially useful at continuous beam sources.}, number={4}, journal={JOURNAL OF RESEARCH OF THE NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY}, author={Markoff, DM and Cianciolo, V and Britton, CL and Cooper, RG and Greene, GL}, year={2005}, pages={449–452} } @article{araki_markoff_al._2005, title={Experimental investigation of geologically produced antineutrinos with KamLAND}, volume={436}, number={7050}, journal={Nature}, author={Araki, T.

The strengths of these amplitudes from theoretical calculations are not well known, and experimental measurements of parity-violating (PV) observables in different nuclear systems have not constrained their values. Transversely polarized cold neutrons traveling through liquid helium experience a PV spin rotation due to the weak interaction with an angle proportional to a linear combination of these weak meson exchange amplitudes. A measurement of the PV neutron spin rotation in helium (φPV (n,α)) would provide information about the relative strengths of the weak meson exchange amplitudes, and with the longitudinal analyzing power measurement in the p + α system, allow the first comparison between isospin mirror systems in weak NN interaction. An earlier experiment performed at NIST obtained a result consistent with zero: φPV (n,α) = (8.0 ±14(stat) ±2.2(syst)) ×10−7 rad / m[1]. We describe a modified apparatus using a superfluid helium target to increase statistics and reduce systematic effects in an effort to reach a sensitivity goal of 10−7 rad/m.}, number={3}, journal={JOURNAL OF RESEARCH OF THE NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY}, author={Bass, CD and Dawkins, JM and Luo, D and Micherdzinska, A and Sarsour, M and Snow, WM and Mumm, HP and Nico, JS and Huffman, PR and Markoff, DM and et al.}, year={2005}, pages={205–208} } @article{markoff_2005, title={Parity-violating neutron spin rotation in a liquid parahydrogen target}, volume={110}, ISSN={["1044-677X"]}, DOI={10.6028/jres.110.026}, abstractNote={Our understanding of hadronic parity violation is far from clear despite nearly 50 years of theoretical and experimental progress. Measurements of low-energy parity-violating observables in nuclear systems are the only accessible means to study the flavor-conserving weak hadronic interaction. To reduce the uncertainties from nuclear effects, experiments in the few and two-body system are essential. The parity-violating rotation of the transverse neutron polarization vector about the momentum axis as the neutrons traverse a target material has been measured in heavy nuclei and few nucleon systems using reactor cold neutron sources. We describe here an experiment to measure the neutron spin-rotation in a parahydrogen target (n-p system) using pulsed cold-neutrons from the fundamental symmetries beam line at the Spallation Neutron Source under construction at the Oak Ridge National Laboratory.}, number={3}, journal={JOURNAL OF RESEARCH OF THE NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY}, author={Markoff, DM}, year={2005}, pages={209–213} } @article{eguchi_gould_markoff_young_messimore_2004, title={High sensitivity search for (nu)over-bar(e)'s from the Sun and other sources at KamLAND}, volume={92}, number={7}, journal={Physical Review Letters}, author={Eguchi, K. and Gould, C.
