Summary
We have examined the differences between a 2-D model and a 3-D model for designing the beam-line shield for the HIPPO instrument at the Lujan Center at the Los Alamos National Laboratory. We have calculated the total (neutron and gamma ray) dose equivalent rate coming out of the personal access ports from the HIPPO instrument experiment cave. In order to answer this question, we have investigated two possible worst-case scenarios: (a) failure of the T₀-chopper and no sample at the sample position; and (b) failure of the T₀-chopper with a thick sample (a piece of Inconel-718, 10 cm diam by 30 cm long) at the sample position.
