Crate nereids_pipeline 

nereids-pipeline

End-to-end orchestration for neutron resonance imaging analysis.

This crate ties together all NEREIDS components into a complete pipeline: data loading → normalization → forward model → fitting → spatial mapping.

Modules

• beam — The beam before the sample, per µs of flight time
• calibration — Energy calibration for TOF neutron instruments (t0 + flight-path scale)
• counts_fit — Densities, temperature, normalization and background fitted to the open-beam and sample counts (fit_counts)
• detectability — Trace-detectability analysis (pre-experiment SNR check)
• error — Pipeline error types
• open_beam — The beam fitted to the open-beam counts (fit_open_beam)
• pipeline — Single-spectrum analysis pipeline (fit_spectrum_typed)
• spatial — Per-pixel parallel mapping with rayon (spatial_map_typed)

Modules

beam

The beam before the sample: neutrons per µs of flight time.

calibration

Energy calibration for TOF neutron instruments.

counts_fit

The areal densities of a sample’s isotopes, its temperature, and the sample run’s normalization and background, fitted to the counts of an open-beam run and a sample run recorded in the same time bins.

detectability

Trace-detectability analysis for neutron resonance imaging.

error

Error types for the nereids-pipeline crate.

joint_fit

Fit a sample together with the calibrant that measured its resolution.

open_beam

The beam, in neutrons per µs of flight time, fitted to the open-beam counts it produces through the instrument pulse.

pipeline

Single-spectrum analysis pipeline.

spatial

Spatial mapping: per-pixel fitting with rayon parallelization.
