In electronic vacuum devices such as a cathode ray tube, the anode is the positively charged electron collector.
2.
The electron collector will be deployed once the primary mission, the attitude determination experiment, has been completed.
3.
Higher powered helix TWTs usually contain beryllium oxide ceramic as both a helix support rod and in some cases, as an electron collector for the TWT because of its special electrical, mechanical, and thermal properties.
4.
As an example, a Daniell cell consists of a zinc anode ( an electron collector ), is oxidized as it dissolves into a zinc sulfate solution, the dissolving zinc leaving behind its electrons in the electrode according to the oxidation reaction ( " s " = solid electrode; " aq " = aqueous solution ):
