| Description | Journal: Plasma Sources Science and Technology Ignition and optimization of the pulsed micro-cathode triggerless vacuum arc thruster model is analyzed. To this end a simplified model of the thruster consisting of two rectangular electrodes on alumina ceramic plate with variable inter-electrode gap covered by conductive film of carbon paint is considered. It is shown that after optimizing the inter-electrode gap, electrical power and the value of magnetic field parallel to film surface, such "idealized" thruster model can provide up to 1.2-1.3 million pulses with the high degree of stability of ignition and amplitude of arc current. These findings may be used in designing of long-living and durable low-power micro-cathode thrusters with the rigidly fixed, unmovable electrodes. We also propose a concept of modular thruster consisting of separate elementary consumable thrusters, which increase the modular thruster lifetime by the number of the elementary thrusters. |
