Abstract: A pulsed high-voltage cylindrical anode layer Hall plasma accelerator is described. The magnetic field is analyzed. The preliminary experiment is performed for the performance test of large scale cylindrical anode layer Hall plasma accelerator working at high power. The results, including the I-V characteristics, anode efficiency, and the feature of the ion beam, etc, are analyzed. It is shown that this device works stably. Additionally, this plasma accelerator can be operated at high power (more than 3kW). Also it has features as such high current utilization efficiency (more than 90%), wide discharge voltage range, small ion-beam divergence. 
