Magnetron unit with a magnetic field compensating means |
摘要 |
A magnetron unit has a magnetic flux path for magnetic flux supplied from a permanent magnet to the interaction space. A magnetic member is disposed outside the anode cylinder for providing a by-path for the magnetic flux supplied from the permanent magnet. This magnetic member is made of a magnetic compensating alloy whose magnetic permeability decreases with an increase in temperature.
