Projection Imaging with Ultracold Neutrons

Kuk, K., Cude-Woods, C., Chavez, C. R., Choi, J. H., Estrada, J., Hoffbauer, M., Holland, S. E., Makela, M., Morris, C. L., Ramberg, E., Adamek, E. R., Bailey, T., Blatnik, M., Broussard, L. J., Brown, M. A.P., Callahan, N. B., Clayton, S. M., Currie, S. 01 July 2021 (has links)
Ultracold neutron (UCN) projection imaging is demonstrated using a boron-coated back-illuminated CCD camera and the Los Alamos UCN source. Each neutron is recorded through the capture reactions with10B. By direct detection at least one of the byproducts α, 7Li and γ (electron recoils) derived from the neutron capture and reduction of thermal noise of the scientific CCD camera, a signal-to-noise improvement on the order of 104 over the indirect detection has been achieved. Sub-pixel position resolution of a few microns is confirmed for individual UCN events. Projection imaging of test objects shows a spatial resolution less than 100μm by an integrated UCN flux one the order of 106 cm−2. The bCCD can be used to build UCN detectors with an area on the order of 1 m2. The combination of micrometer scale spatial resolution, low readout noise of a few electrons, and large area makes bCCD suitable for quantum science of UCN.
