Magnetic field generating means for a magnetron tube, the magnetron and a method for the exchange of an old magnetron tube of a magnetron against a new magnetron tube

摘要

The invention relates to a magnetic field generating means (2) for a magnetron (1) with a permanent magnet assembly (4) and a magnetic field conductor means (6). The magnet field guide means (6) has a conduction element on. Which consists of a plurality of rectangular discharge line segments, conduction element is detachably in the case of maintenance work on the magnetic field generating means (2) is provided by the permanent magnet arrangement (4) generated magnetic field of further components of the magnetic field generating means (2) and components of the magnetron (1) to deflect. The present invention also relates to a magnetron (1) with a magnetron tube (3) and with a magnetic field generating means (2). The magnetic field generating means (2) is designed as described above. In addition, the invention relates to a method for exchanging an old magnetron tube (3) of a as described above, magnetron (1) against a new magnetron tube (3). In a first step, the conduction element on the magnetic field generating means (2) is arranged. In a subsequent step, the old magnetron tube (3) of the magnetron (1) is removed, and by means of the new magnetron tube (3) is replaced, in order subsequently to remove the conduction element.
