Software for Optimizing Filter Stack Spectrometer Design and Unfolding Spectra

In this poster, we present a software suite for 1) characterizing FSS designs and 2) unfolding spectra from raw FSS data. Unfolding spectra from filter-stack spectrometers requires a detailed response matrix---the average energy deposited in each image plate per incident photon at a certain energy. In principle, the same unfolding algorithms can work for other detectors such as scintillators. We provide scripts and analysis tools that automate the creation of a response matrix using the particle transport code MCNP. We additionally provide software that, given a response matrix and raw FSS data, performs the unfold using a new perturbative minimization algorithm and produces a spectrum. This software is planned for open source release.
