Duoplasmatron
The duoplasmatron is a device for generating powerful ion currents. It was invented in 1948 by Manfred von Ardenne in the Soviet Union and developed further until 1956 to be patentable .
Structure and functionality
The ions are extracted from a gas discharge that is maintained in a magnetic field with an electron beam .
The principle applied here is also used in other plasmatron ion sources, such as the unoplasmatron (von Ardenne, 1948) and the duopigatron (Demirkanov, 1964).
commitment
The areas of application of the Duoplasmatrons range from nuclear and elementary particle research to industrial use. Duoplasmatrons are used, for example, as an ion source in various types of particle accelerators .
The Kaufman ion source is a further development of the Duoplasmatrons . She was u. a. First used in space travel as an ion drive in 1998 for the Deep Space 1 mission.
Duoplasmatrons are used as an ion source in secondary ion mass spectrometry .
