Crate lindhard 

lindhard — clean-room Monte Carlo transport of ions and electrons in matter.

Roadmap, milestone status and the module plan are in docs/architecture.md. Each module’s own documentation is the maintained description of what it provides:

• constants: physical constants in SI units, each with its source.
• contour: iso-dose contours of a gridded field, with area and centroid.
• electron: electron transport, from validated data to tallies.
• elements: the per-element data table, Z = 1..=92.
• exposure: dose of a multi-shot exposure from a fitted Gaussian-sum PSF.
• geometry: the Geometry trait and the layered, voxel and mesh targets.
• input: the TOML run description (beam, target, physics, run size).
• ion: ion transport, screening, stopping, damage and crystal targets.
• material: elements combined into materials with their energies.
• rng: deterministic per-particle random streams and the parallel driver.
• tally: histograms, moments, distributions and other result statistics.
• units: unit conventions and conversions.

Modules

constants

Physical constants, SI units.

contour

Iso-dose contours of a gridded scalar field, with the area and centroid of each closed contour.

electron

Electron transport (milestone M1, docs/architecture.md).

elements

Element table, Z = 1..=92.

exposure

Multi-shot exposure: the energy density deposited by a list of shots, from a fitted Gaussian-sum point-spread function (GaussianPsf).

geometry

Target geometry: the engine-facing Geometry trait, the 1D layered Stack, the 3D VoxelGrid, the triangle-mesh MeshGeometry and the constructive-solid-geometry CsgGeometry.

input

The run description: one TOML document describing the beam, the layered target and its materials, the physics choices and the run size.

ion

Ion transport: screened potentials, scattering, stopping, the BCA engine, and the crystal-target data model (crystal).

material

Materials: elements combined by atom or mass fraction, with a mass density, a derived atom number density, and per-element displacement (E_d), lattice binding (E_b) and surface binding (E_s) energies.

rng

Deterministic per-particle random streams and a parallel driver.

tally

Tallies: turning particle histories into results.

units

Unit conventions.
