`arcback ‘The flow of a principal electron stream in the

`because of formation of a cathode spot on an anode. This
`results in failure of the rectifying action. Also called back-

`arccathode A cathade in which electron emissionis self-
`sustaining at a low voltage drop, approximately equal to
`the ionization potential of the gas.
`arc-discharge tube A discharge tube in which a high-
`current arc discharge passes through the gas between the
`electrodes, generally for the purpose of producing an
`latense flash of light.
