Detection of ultracold neutrons with powdered scintillator screens
M. Krivos, N. C. Floyd, C. L. Morris +24
Zinc sulfide (ZnS:Ag) scintillators coated with a thin 10B layer are widely used for ultracold neutron (UCN) detection, but their application is limited by long decay times and sig…
YAP:Ce scintillator as an absolute ultracold neutron detector
M. Krivoš, Z. Tang, N. Floyd +14
The upcoming UCNProBe experiment at Los Alamos National Laboratory will measure the -decay rate of free neutrons with different systematic uncertainties than previous beam-based…
Scintillation characteristics of the EJ-299-02H scintillator
N. Floyd, Md. T. Hassan, Z. Tang +15
A study of the dead layer thickness and quenching factor of a plastic scintillator for use in ultracold neutron (UCN) experiments is described. Alpha spectroscopy was used to deter…
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…
Characterization of the new Ultracold Neutron beamline at the LANL UCN facility
D. K. -T. Wong, M. T. Hassan, J. F. Burdine +12
The neutron electric dipole moment (nEDM) experiment that is currently being developed at Los Alamos National Laboratory (LANL) will use ultracold neutrons (UCN) and Ramsey's metho…
Ultracold Neutron Properties of the Eljen-299-02D deuterated scintillator
Z. Tang, E. B. Watkins, S. M. Clayton +24
In this paper we report studies of the Fermi potential and loss per bounce of ultracold neutron (UCN) on a deuterated scintillator (Eljen-299-02D). These UCN properties of the scin…
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…
Monte Carlo Simulations of Trapped Ultracold Neutrons in the UCNτ Experiment
Nathan Callahan, Chen-Yu Liu, Francisco Gonzalez +37
In the UCNτ experiment, ultracold neutrons (UCN) are confined by magnetic fields and the Earth's gravitational field. Field-trapping mitigates the problem of UCN loss on material s…
Solid deuterium surface degradation at ultracold neutron sources
A. Anghel, T. L. Bailey, G. Bison +27
Solid deuterium (sD_2) is used as an efficient converter to produce ultracold neutrons (UCN). It is known that the sD_2 must be sufficiently cold, of high purity and mostly in its…
Evaluation of commercial nickel-phosphorus coating for ultracold neutron guides using a pinhole bottling method
R. W. Pattie, E. Adamek, T. Brenner +24
We report on the evaluation of commercial electroless nickel phosphorus (NiP) coatings for ultracold neutron (UCN) transport and storage. The material potential of 50~m thick Ni…
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…
Storage of ultracold neutrons in the UCN magneto-gravitational trap
D. J. Salvat, E. R. Adamek, D. Barlow +29
The UCN experiment is designed to measure the lifetime of the free neutron by trapping ultracold neutrons (UCN) in a magneto-gravitational trap. An asymmetric bowl-shape…
