NSRL experimental neutron yields from GCR-like ions incident on dual thick targets
Description
This repository contains all experimental neutron results from the dual-thick-target experiments conducted at NSRL in 2016 and 2017. These text files are from the final official data repository for this experiment. The experiment is described here: https://trace.tennessee.edu/utk_nuclpubs/7/ The full analysis procedures for characterizing the neutrons are comprehensively discussed in the dissertation by Hunter N. Ratliff linked below. https://trace.tennessee.edu/utk_graddiss/5323/ Two additional papers in preparation (and hopefully published as of your reading this) provide a higher-level overview of the analyses and are entitled: 1) "Double-differential primary target neutron yields from dual-thick-target proton and heavy ion accelerator experiments" 2) "Development of scalable deconvolution methods for determining secondary target neutron yields from dual-thick-target cosmic-ray ion accelerator experiments" and are authored by: H.N. Ratliff, N.A. McGirl, M.R. Beach, L.A. Castellanos, M.S. Clowdsley, L.H. Heilbronn, C. La Tessa, J.W. Norbury, A. Rusek, M. Sivertz, A.P. Srikrishna, H. Wang, and C. Zeitlin Data for neutrons from the primary target characterized with time-of-flight techniques are in the folder called "primary-target-neutrons" while the data for neutrons from the secondary target characterized with a detector response-based deconvolution methodology are in the "secondary-target-neutrons" folder. The "supplemental_information" folder contains a visual aid showing the design of the experiment, a table stating the stopping location of each beam, and a table containing the experimental schedule for when each beam+target combination was tested. In the data folder, each filename is composed of 7 components separated by underscores: 1) experiment date (see experiment_schedule_table.pdf) 2) beam (species and energy divided by 100) 3) primary target (material and mass thickness) 4) detector type (all OLS in this repository) 5) detector angle 6) particle type (N=primary target neutron, NDC=secondary target neutron) 7) repository internal version number The header in the top portion of each file fully details all of this information too. For the secondary target results, the "Additional Notes:" line was not properly updated and incorrectly indicates that the results are preliminary. This is false. The results included in this repository are final. The statement about the midpoints being arbitrarily assigned and being log-spaced midpoints is correct though. The Google Drive document mentioned was an internal document which is not made available as its explanations are superseded by official publications explaining the analyses and data.
