Webb1 sep. 2016 · An indirectly heated oxide coated cathode plasma source has been constructed on a linear magnetized plasma device. The electron emission current density can reach 2 A/cm 2 to 6 A/cm 2 in pulsed mode within pulse length 5–20 ms. WebbIt is believed that there are two primary theories which explain how an ALD coating layer protects the cathode materials. The first theory is that the coated materials replace the active substances which react with HF (such as Al 2 O 3, TiO 2 ), but do not provide protection when the coated material is heavily eroded by HF.
