Measurement of the Free Neutron Lifetime in a Magneto-Gravitational Trap with In Situ Detection
R. Musedinovic, L. S. Blokland, C. B. Cude-Woods +32
Here we publish three years of data for the UCNtau experiment performed at the Los Alamos Ultra Cold Neutron Facility at the Los Alamos Neutron Science Center. These data are in ad…
An experimental search for an explanation of the difference between beam and bottle neutron lifetime measurements
M. F. Blatnik, L. S. Blokland, N. Callahan +32
The past two decades have yielded several new measurements and reanalysis of older measurements of the neutron lifetime. These have led to a 4.4 standard deviation discrepancy betw…
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 $38\…
A boron-coated CCD camera for direct detection of Ultracold Neutrons (UCN)
K. Kuk, C. Cude-Woods, C. R. Chavez +48
A new boron-coated CCD camera is described for direct detection of ultracold neutrons (UCN) through the capture reactions B (n,0)Li (6%) and B(n,1)$^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…
Measurement of the neutron lifetime using a magneto-gravitational trap
Nathan Callahan
Precision measurements of the free neutron lifetime , when combined with measurements of the axial vector form factor, can be used to test unitarity of the CKM matrix. Non-uni…
Measurement of the neutron lifetime using an asymmetric magneto- gravitational trap and in situ detection
R. W. Pattie, N. B. Callahan, C. Cude-Woods +35
The precise value of the mean neutron lifetime, , plays an important role in nuclear and particle physics and cosmology. It is a key input for predicting the ratio of protons…
A new method for measuring the neutron lifetime using an in situ neutron detector
C. L. Morris, E. R. Adamek, L. J. Broussard +28
The neutron lifetime is important in understanding the production of light nuclei in the first minutes after the big bang and it provides basic information on the charged weak curr…
Foil Diffuser Investigation with GEANT4
Joseph M. Fabritius, Konstantin Borozdin, Peter Walstrom
An investigation into the appropriate materials for use as a diffuser foil in electron radiography was undertaken in GEANT4. Simulations were run using various refractory materials…
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…
