🔬 Neutron Time-of-Flight Powder Diffraction: Bragg Peaks and Resolution (2D instrument view)

2D view of a pulsed-source neutron powder diffractometer. Choose a lattice, the flight path, the detector bank angle and the resolution terms, and watch a Poisson-noisy time-of-flight histogram build up with one peak per allowed reflection, converted to d-spacing, with the resolution curve and the lambda = h t / (m L) relation. Same physics as the 3D explorer, with five in-page numerical checks.
