2D21 Thyratron: From GE Datasheet Curves to a Level-1 Compact Model

Written by giux | Published on Sep 16, 2026 | No comments

Starting from the characteristic curves published by General Electric, I digitized and analyzed the 2D21 thyratron grid current to build a reproducible compact mathematical model. In this article I describe the full process, from replicated digitizations and uncertainty estimation to family normalization, identification of common functions, and quantitative validation of the 2D21 Level-1 v0.1 model.
