The science · equations and limitations
Actual physical principles: ionization electrons drift under an applied electric field, a graded ring system helps shape the field, and segmented readout can encode charge arrival.
Textbook relationships: E = V / L; vd = μeffE; t = L/vd; σT = √(2DTt); Q = NeeG. The effective mobility and diffusion coefficient are held constant for demonstration and must not be used to predict a real gas detector.
Independent check: the displayed drift time is also recalculated directly as L/(μeff × E), independently of the velocity-based engine computation. Differences are displayed above.
Engineering-inspired: the vessel, shielding layers, mechanical supports, DAQ and calibration arrangements are reconstructions, not specifications.
Simplified: no field solver, gas transport database, particle energy deposition, electronics noise, pressure model, or backgrounds are simulated. Moving points visualize conceptual electron drift and are not measured trajectories.
Speculative: assembly architecture, dimensions and device identity are fictional. Geometry dimensions are scaled for clarity.
Illustrative design, not affiliated with any real institution or manufacturer.
