Small Public-API Consumers

User question	Current source	What to study
proton range and depth deposition	benchmarks/proton_csda_range/proton_csda_range.cc	grid geometry, PSTAR data, source, scalar and binned observables
alpha range	benchmarks/alpha_csda_range/alpha_csda_range.cc	ASTAR data and alpha package configuration
coupled gamma shielding	benchmarks/radioisotope_gamma_shielding/radioisotope_gamma_shielding.cc	decay source, coupled EM data, detector dose and response bins
positron annihilation	benchmarks/positron_annihilation/positron_annihilation.cc	positron transport, annihilation photons and mixed observables
electron depth dose	benchmarks/electron_range_dose/electron_range_dose.cc	charged EM stepping and depth-resolved deposition
decay source rates	benchmarks/decay_source_term/decay_source_term.cc	imported decay data without a transport application
inventory evolution	benchmarks/decay_inventory_chain/decay_inventory_chain.cc	decay-chain source preparation

Experiment And Evidence Consumers

Programs under tools/ exercise newer or narrower capabilities. Experiment results run through SimulationModel, while some files also contain explicitly private diagnostic calculations:

Topic	Source
microscopic light-water angular response	tools/light_water_thermal_angular_scattering.cc
positron returned-current experiment	tools/positron_aluminum_backscatter.cc
O-16 photonuclear competition and mixed handoff	tools/o16_photoneutron_production.cc
electron K-shell ionization response	tools/cu_electron_k_shell_ionization.cc
activation, cooling and decay transport	tools/fng_iter_activation_dose.cc
fission eigenvalue and source convergence	tools/fast_metal_critical_mass.cc and tools/fission_eigenvalue_observable_audit.cc

These are not generic application templates. Reuse their public resolver and model-building patterns, not their experiment-specific constants, detector corrections, comparisons or private diagnostic sections.

Choose An Example

Prefer the consumer that matches all four parts of your question:

1. source particle and energy;
2. material and geometry class;
3. physical processes and data representation;
4. final observable.

A program that shares only the particle type can still require a different physics package configuration or estimator.
