Fundamental Neutron Physics: a White Paper on Progress and Prospects in the US
R. Alarcon, A. Aleksandrova, S. Baeßler +88
Fundamental neutron physics, combining precision measurements and theory, probes particle physics at short range with reach well beyond the highest energies probed by the LHC. Sign…
Demonstration of Sub-micron UCN Position Resolution using Room-temperature CMOS Sensor
S. Lin, J. K. Baldwin, M. Blatnik +25
High spatial resolution of ultracold neutron (UCN) measurement is of growing interest to UCN experiments such as UCN spectrometers, UCN polarimeters, quantum physics of UCNs, and q…
Fill and dump measurement of the neutron lifetime using an asymmetric magneto-gravitational trap
C. Cude-Woods, F. M. Gonzalez, E. M. Fries +39
The past two decades have yielded several new measurements and reanalyses of older measurements of the neutron lifetime. These have led to a 4.4 standard deviation discrepancy betw…
Improved neutron lifetime measurement with UCN
F. M. Gonzalez, E. M. Fries, C. Cude-Woods +41
We report an improved measurement of the free neutron lifetime using the UCN apparatus at the Los Alamos Neutron Science Center. We counted a total of approximately $38\…
Improved limits on Fierz Interference using asymmetry measurements from the UCNA experiment
Xuan Sun, E. Adamek, B. Allgeier +56
The Ultracold Neutron Asymmetry (UCNA) experiment was designed to measure the -decay asymmetry parameter, , for free neutron decay. In the experiment, polarized ultracold n…
A New Cryogenic Apparatus to Search for the Neutron Electric Dipole Moment
M. W. Ahmed, R. Alarcon, A. Aleksandrova +91
A cryogenic apparatus is described that enables a new experiment, nEDM@SNS, with a major improvement in sensitivity compared to the existing limit in the search for a neutron Elect…
Final results for the neutron -asymmetry parameter from the UCNA experiment
B. Plaster, E. Adamek, B. Allgeier +91
The UCNA experiment was designed to measure the neutron -asymmetry parameter using polarized ultracold neutrons (UCN). UCN produced via downscattering in solid deuterium w…
A boron-coated CCD camera for direct detection of Ultracold Neutrons (UCN)
K. Kuk, C. Cude-Woods, C. R. Chavez +48
A new boron-coated CCD camera is described for direct detection of ultracold neutrons (UCN) through the capture reactions B (n,0)Li (6%) and B(n,1)$^7…
Cavallo's Multiplier for in situ Generation of High Voltage
Steven M. Clayton, Takeyasu M. Ito, John C. Ramsey +4
A classic electrostatic induction machine, Cavallo's multiplier, is suggested for in situ production of very high voltage in cryogenic environments. The device is suitable for gene…
Search for dark matter decay of the free neutron from the UCNA experiment: n
X. Sun, E. Adamek, B. Allgeier +57
It has been proposed recently that a previously unobserved neutron decay branch to a dark matter particle () could account for the discrepancy in the neutron lifetime observed i…
Detection System for Neutron Decay Correlations in the UCNB and Nab experiments
L. J. Broussard, B. A. Zeck, E. R. Adamek +51
We describe a detection system designed for precise measurements of angular correlations in neutron decay. The system is based on thick, large area, highly segmented silicon de…
A multilayer surface detector for ultracold neutrons
Zhehui Wang, M. A. Hoffbauer, C. L. Morris +33
A multilayer surface detector for ultracold neutrons (UCNs) is described. The top B layer is exposed to the vacuum chamber and directly captures UCNs. The ZnS:Ag layer benea…
