Idly wondering why electrostatic CRTs were comparatively rare outside of electrical test equipment. Why did they always use electromagnetic ones that are harder to drive? Or are they easier to drive and we're just wrong?

@Felthry I think the larger you scale them up the less effective electrostatic controls were.
It's also entirely possible that electromagnets were just cheaper too.
@Felthry Ah here we go
"Electrostatic deflection is very useful for small deflection angles but is well known to be inferior to magnetic deflection for deflecting a charged particle beam into large angles - say over 10 degrees"

@DarkOverord oh that makes sense! it's just easier in general to control a current than a voltage.
