<p>PURPOSE: To obtain an ionization chamber for a plasma-generating device which is capable of pre-ionizing gas, without using constituent elements which may tend to possibly lower the reliability of a whole system. CONSTITUTION: An adequate ionization radiation source 47 is provided, so as to improve the capacity of this device, in an ionization chamber 21 for a plasma- generating device, used for utilization for ion propulsion or satellite discharge in a space field and on the ground. A radiation beam, emitted by the radiation source, creates constant ionization, having an advantage with respect to a preliminary ionization step, that is, both the starting time and operating step of the device, to standardize the capacity of a device by the continuation and regulation of the operation in particular.</p> |
