\nThe HVEE Model 358 Duoplasmatron ion source is a modified Von Ardenne ion source and useful as a source of plasma for subsequent extraction of positive and negative ions. In its design care has been taken to utilize high vacuum techniques that will minimize contamination and contribute to efficient operation and pure ion
\nbeam outputs.
\nA low-pressure arc discharge in the gas to be ionized is electrostatically constricted by a funnel-shaped intermediate electrode placed between the electron-emitting cathode (hot filament) and the anode. A strong axial magnetic field between the intermediate electrode and the anode further constricts the discharge to a narrow plasma beam along the axis of the exit aperture.
\nTo increase the evacuation speed of the arc chamber during initial filament out gassing the HVEE Model 358 Duoplasmatron ion source is provided with a valve to bypass the extraction aperture.
\nAn important feature of the design is that wearable and serviceable components – such as intermediate electrode, anode aperture and filament – are easily replaceable. The filament design has been field-tested and has an expected life inexcess of 1000 hours in a hydrogen atmosphere and under normal operating conditions.<\/p>\nHigh Voltage Engineering<\/a>\nModel 358<\/a>\n\u53cc\u7b49\u79bb\u5b50\u4f53\u79bb\u5b50\u6e90<\/a>\n\u56fa\u76f8\u79bb\u5b50\u6e90<\/a>\n\u5c04\u9891\u79bb\u5b50\u6e90<\/a>\n\u6c14\u76f8\u79bb\u5b50\u6e90<\/a>\n\u6db2\u76f8\u79bb\u5b50\u6e90<\/a>\n\u771f\u7a7a\u6d4b\u8bd5<\/a>\n\u771f\u7a7a\u8154<\/a>\n\u79bb\u5b50\u6e90<\/a>\n\u94ef\u79bb\u5b50\u67aa<\/a><\/div>","protected":false},"excerpt":{"rendered":"
