Development of estimation function of systematic uncertainty in PHITS

Hashimoto, Shintaro  

PHITS based on the Monte Carlo method has been used for many purposes such as radiation shielding in accelerator facilities. In order to confirm reliability of PHITS results, not only statistical errors related to the number of trials but also systematic uncertainties attributed to errors of input such as material densities are required. We implemented an estimation function of statistical errors and systematic uncertainties based on analysis of variance (ANOVA) in PHITS. In this presentation, we will introduce the estimation method using ANOVA, and explain how to use a sub-program autorun which can be used to easily obtain the error and uncertainty.
