Abstract
A method for manufacturing a tubular part for travelling-wave tubes, which includes firmly placing a magnetically soft tube on a cylindrical body, cutting the magnetically soft tube into individual annular pole pieces having planar lateral surfaces throughout, inserting a ring of non-magnetic material between each two respective annular pole pieces, soldering the non-magnetic rings to the annular pole pieces, removing the cylindrical body after the soldering step, and inserting a magnet between each two respective annular pole pieces.

Method for manufacturing a tubular component for a travelling wave tube, the component which consists of alternating soft-magnetic and non-magnetic rings, having axially magnetized ring-magnets, that are alternatingly magnetized in opposite directions, the method which comprises the steps of:
- firmly placing a magnetically soft tube on a cylindrical body,
- cutting the magnetically soft tube into individual ring-shaped, annular pole pieces having planar, lateral, parallel, radially oriented surfaces throughout,
- inserting a ring of non-magnetic material between each two consecutive annular pole pieces,
- soldering the non-magnetic rings to the annular pole pieces,
- removing the cylindrical body after completing the soldering step, and
- inserting a magnet between each two consecutive annular pole pieces.
