The magnetron carries the part number for itself. You can sight it by removing the cover. Parts are available from the maker or repairs agents. However, the cost of a new magnetron may exceed the cost to replace the Microwave Oven.
Before removing the cover of the oven in attempt to carry out any maintenance such as replacing the Oven cavity lamp, make sure the oven is disconnected from the power point ! The voltages in a microwave oven ARE LETHAL !

1) How is the cavity damaged? Is it just peeling paint, or is it rust? If it's rust then the microwave could be dangerous.
2) The antenna cap usually has a small hole in the centre, but if there are any other holes in it the magnetron itself could be damaged, and holes caused by the magnetrin arcing.

It appears to be from detecting an arc due to insulation fault such as a punctured sleeve or too close to a conductor with dust and humidity.
This may be difficult or easy depending on your hands on skills. With power unplugged at all times, the big cap inside will self-discharge.
