Physics-accurate virtual water tank. Build your setup, deliver a beam, work through the protocol. Every reading comes from a real model of the geometry you configure — no fudge toward the right answer.

BetaSimulator in active development. Treat numbers as pedagogical, not clinical — protocol values, kQ tables, and workflows are still being tuned. Report issues through the in-app feedback so we can iterate quickly.

Locks the setup, sweeps the chamber from from to toin step-cm increments, and logs a reading at each. Small step + wide range gives a dense PDD curve. Auto-jumps to the PDD plot tab when done.

Printed from Get-Boarded TG-51 simulator. Values are training values, not measured on a real machine.
Work through the protocol yourself. Nothing here is auto-filled from the machine: every value must come from your own readings and arithmetic. The final entry is checked against the machine's true output at dmax for a 10×10 field at SSD 100, tolerance ±1%.
