Maltese Cross Tube D – 1000649
High-vacuum electron tube with divergent electron gun aimed at afluorescent screen partially obscured by a Maltese cross. Fordemonstrating the linear propagation of electrons in the absence ofapplied electromagnetic fields by projecting the shadow of a Maltesecross onto the fluorescent screen. Application of a magnetic field usingthe Helmholtz Coils S allows for students to study the fundamental science of electron optics, such as beam focusing.
