GuideSAED Indexing, g-Vectors & Real vs. Fake SpotsInteractive guide to indexing SAED patterns by hand: measure g-vectors from spot ratio and angle, see whether those two numbers name one zone axis or several at your measurement precision, and score a twin, double diffraction and a second phase against the same extra spots.GuideFrom Kikuchi Bands to an OrientationEBSD & TKD, part 1 of 8: From Kikuchi bands to an orientation. Interactive.GuideInstrument, Prep & ApplicationsVoltage-pulsed versus laser-pulsed atom probe, FIB lift-out and annular milling of a site-specific needle, grain-boundary segregation, and correlative APT + TEM. Interactive explainers.

GuideWhen Forbidden Reflections AppearInteractive guide to forbidden reflections and superlattices in TEM: why spots are systematically absent, the mechanisms that make them appear (double diffraction, relrods, stacking faults), and a field guide to superlattices in metals and alloys: chemical ordering, the omega phase, long-period structures and their look-alikes.GuideGrain Orientations & Reciprocal SpaceInteractive TEM guide to grain orientations in reciprocal space: zone-axis tilts with Laue circle and Kikuchi lines, misorientation (LAGB, HAGB, twins), polycrystalline rings and texture arcs, and orientation terminology.GuideWeak-Beam Dark FieldInteractive guide to weak-beam dark field: why strong-beam dislocation images are fat (Pendellösung and extinction distance), the g–3g tilt walkthrough on the Ewald sphere, a Howie–Whelan dislocation-image simulator, the g·b invisibility criterion, and measuring stacking-fault energy from partial separation in Cu.GuideHRTEM & FFTsInteractive guide to HRTEM and FFTs: a defocus/CTF lattice-image simulator with a true atom-column overlay, the Scherzer-defocus CTF explorer, measuring d-spacings from an FFT with a draggable ROI, how Fourier filtering can conjure fake lattices from noise, and FFT versus SAED.GuideReconstruction & ResolutionHow an atom probe turns detector hits into a 3-D map of atoms: trajectory aberrations and local magnification near a precipitate, and why APT resolves atomic planes in depth but blurs laterally. Interactive explainers.GuideData & AnalysisUntangling an atom probe mass spectrum: peak overlaps and isotopic deconvolution, iso-concentration surfaces and proximity histograms, and counting statistics in a tip of a few million atoms. Interactive explainers.
