Abstract
CERTAIN types of cathode-ray tubes in which the luminous spot on the fluorescent screen is moved by magnetic fields are liable to a peculiar defect, known as 'ion spot' or 'ion burn'. It is now thought that in most cases they are due to ions issuing from the thermionic cathode. This conclusion was mainly reached by inference from the composition of the ion stream which was analysed by mass-spectroscopic methods by several investigators1,2,3.
