Magnesium ion source for high intensity mass spectrograph

[摘要] Magnesium ions were produced by bombarding magnesiumvapor by electrons emitted tram oxide coated cathodes. The ionswere then focussed into a thin sheet by means of an electrostaticlens. This ion sheet was sent into the magnetic lens whichfocussed the sheet into a small spot where they were collected.The ion current obtained at the collector was 120 microamperes.
