November 2016 HERMES Outdoor Shot Series 10268-313: Courtyard Dosimetry and Parametric Fits

Cartwright, Keith C.; Yee, Benjamin T.; Pointon, Timothy D.; Gooding, Renee L.

A series of outdoor shots were conducted at the HERMES III facility in November 2016. There were several goals associated with these experiments, one of which is an improved understanding of the courtyard radiation environment. Previous work had developed parametric fits to the spatial and temporal dose rate in the area of interest. This work explores the inter-shot variation of the dose in the courtyard, updated fit parameters, and an improved dose rate model which better captures high frequency content. The parametric fit for the spatial profile is found to be adequate in the far-field, however near-field radiation dose is still not well-understood.
