Klystrons/Gyrotrons

Klystrons and gyrotrons are devices that are used to amplify microwave and radio frequencies.

At Dexter, we do not make klystrons and gyrotrons. We do make the magnetic assemblies that enable these devices to operate effectively.

Our permanent magnet structures allow more compact gyrotron shapes.  We have produced 1.4 Tesla in a permanent magnet tube.

DESIGN HELP

Important note: We do not make klystrons and gyrotrons. We make the magnetic assemblies that enable these devices to operate effectively. In order to design a magnet assembly, we would need to know:

  1. Size of gyrotron
  2. Magnetic field strength
  3. Distances between key regions (Collector/Cavity/Gun)

Neodymium Iron Boron and Samarium Cobalt are often used when large magnetic fields are required.  Ceramic (hard ferrite) is used if cost is more important than large magnetic fields.

FAQS

What is the largest possible magnetic field? We have achieved 1.4 Tesla (axial).

PROTOTYPING/TURNAROUND

The design of a magnet assembly for klystrons and gyrotrons is iterative.  It is usually a back-and-forth process because compromises between magnetic field strength and position need to be made.  A relatively straightforward design can be completed within one week, but more complicated designs can take longer.
