cathodal

cathodically
cathodic
cold cathode
(electronics) A type of cathode that does not use a heating element to produce emission of cathode rays (electrons), beyond base thermionic emission (usually by field electron emission, secondary emission, photoelectric emission)
cold-cathode
hot cathode
The heated cathode of a thermionic valve
cathode ray
(electricity) A ray consisting of a stream of electrons in a vacuum tube, that are emitted by the cathode and accelerated towards the anode by an electric field.
