It is often useful to generate synthetic data based on these diagnostics to validate and tune models. However, current methods of doing so using Monte Carlo particle tracing are time-consuming. In this paper, an ultra-fast method is presented for generating synthetic neutron images, RTNAD data, and spectrometry data using line integrals and 3D convolutions. While it does not contain as much physics as particle tracing codes, it is thousands of times faster and produces nearly identical data. This enables analysis techniques that depend on generating large amounts of synthetic data, which will prove very useful for the study of asymmetries going forward.<\/jats:p>","DOI":"10.1063\/5.0309367","type":"journal-article","created":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T13:58:37Z","timestamp":1777643917000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["An ultra-fast method for generating synthetic down-scattered neutron data for inertial confinement fusion implosions"],"prefix":"10.1063","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7076-5891","authenticated-orcid":false,"given":"J.
