61. Effects of high intensity neutron flux on in-situ spin-exchange optical pumping of He-3
Thomas R Gentile, E Babcock, Stephen Boag, C. Becham, T E. Chupp, G L. Jones, A K. Petukhov, T G Walker
Prior studies revealed neutron beam-induced alkali-metal spin relaxation in 3He
cells polarized in-situ by spin-exchange optical pumping. These effects are minor for neutron
beams of low to moderate intensity, but become important at the highest ne ...
62. Making Kilopixel X-Ray Microcalorimeter Arrays a Reality
William Bertrand Doriese, Megan E. Eckart
To enable unprecedented imaging X-ray spectroscopy, scientists at NASA's Goddard Space Flight Center and the National Institute of Standards and Technology are developing arrays of high-resolution microcalorimeters and their readout.
