Abstract
A Hall effect plasma accelerator comprises an annular accelerating channel (1) having closed and open ends. A source of magnetic field (11), in a hollow annular magnetic body (6), is positioned behind the closed end of the channel and has an axis extending in the same direction as the axis of the channel. This makes it possible to provide a Hall effect accelerator with an optimum distribution of magnetic field inside the acceleration channel by means of a simpler and less heavy arrangement using a single source of magnetic field, such as a single coil or permanent magnet. In addition it makes possible a reduction in heating of the source of magnetic field.
Claims
1. A closed electron drift Hall effect plasma accelerator comprising: a substantially annular accelerating channel having closed and open ends where the channel encircles a central vertical axis of the accelerator; an anode within the channel and located at the closed end of the channel; a first magnetic body spaced apart from the channel and enclosing the outside of the closed end of the channel to form a cavity between the bottom of the closed end of the channel and the first magnetic body and extending upwards on both sides of the channel towards the open end of the channel for defining magnetic poles of opposite polarity on opposite sides of the channel; and a source of magnetic field located within the cavity for creating a first magnetic circuit with the first magnetic body to form a magnetic field extending radially across the channel.
2. A closed electron drift Hall effect plasma accelerator comprising: a substantially annular accelerating channel having closed and open ends where the channel encircles a central vertical axis of the accelerator; an anode within the channel and located at the closed end of the channel; a first magnetic body spaced apart from the channel and enclosing the outside of the closed end of the channel to form a cavity between the bottom of the closed end of the channel and the first magnetic body and extending upwards on both sides of the channel towards the open end of the channel for defining magnetic poles of opposite polarity on opposite sides of the channel; a source of magnetic field located within the cavity for creating a first magnetic circuit with the first magnetic body to form a magnetic field extending radially across the channel; and a second magnetic body physically separated from and located between the channel and the first magnetic body and enclosing the outside of the closed end of the channel and extending upwards on both sides of the channel towards the open end of the channel to a point past the location of the anode within the channel for shielding the anode from the magnetic field generated by the source of magnetic field.
3. The accelerator of Claims 41 or 42 wherein the source of magnetic field has a magnetic axis extending in the same direction as the central vertical axis of the accelerator.
4. The accelerator of Claims 41 or 42 wherein the source of magnetic field has a magnetic axis extending around the central vertical axis of the accelerator.
5. The accelerator of Claims 41 and 42 wherein the source of magnetic field comprises a single electromagnet.
6. The accelerator of Claims 41 and 42 wherein the source of magnetic field comprises a single permanent magnet.
7. The accelerator of Claims 41 and 42 wherein the first magnetic body comprises two cylindrical walls coaxial with the channel and arranged either side of the channel and a linking member linking the two cylindrical walls behind the closed end of the channel for forming the cavity behind the closed end of the channel for receiving the source of magnetic field.
