- Title
Measurement of the <sup>235</sup>U(n,f) cross section using the Alpha-Gamma Flux Measurement Device.
- Authors
Adamek, Evan
- Abstract
The Alpha-Gamma device at the National Institute of Standards and Technology utilizes the interaction of neutrons with a totally absorbing l0B target to precisely measure the flux of a monochromatic neutron beam. This apparatus has been used to calibrate the 6Li(n,a)3H based flux monitor which the NIST neutron beam lifetime experiment BL2 used in its measurement of the most precise neutron beta decay lifetime to date. The unique geometry and measurement technique of Alpha-Gamma allows for a competitive measurement of neutron interaction cross sections, such as the uranium-235 fission cross section (n,f). A description of Alpha-Gamma design and preliminary results pertaining to this application will be discussed.
