**Manufacturer:** 3B Scientific  
**MPN:** `U18553`

The 3B Scientific U18553 Teltron Maltese-Cross Electron Tube S is a high-vacuum electron tube designed for demonstrating the linear propagation of electrons in the absence of applied electromagnetic fields. It features a divergent electron gun aimed at a fluorescent screen partially obscured by a maltese cross, allowing for the projection of the shadow of a maltese cross onto the fluorescent screen. The tube operates at a maximum filament voltage of 6.3 VAC.
