Magnetic field extraction of positive ions

Click For Summary

Discussion Overview

The discussion centers on the extraction of positive ions produced from nuclear fission using a magnetic mirror. Participants explore the necessary magnetic field strength required to guide these ions without interaction with surrounding materials, considering various parameters such as particle velocity, mass, and charge.

Discussion Character

  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant inquires about the magnetic field strength needed for the extraction of fast-moving positive ions from a fission process.
  • Another participant notes that the required field strength depends on the velocity and mass of the ions, as well as their charge to mass ratio.
  • A specific average charge of +22 is mentioned, along with average masses of 140 amu and 95 amu for the particles.
  • One participant expresses a lack of expertise in the mathematical details and suggests seeking assistance in a specialized forum.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specific magnetic field strength required, and the discussion remains unresolved regarding the calculations and methodologies involved.

Contextual Notes

The discussion lacks detailed mathematical formulations and assumptions regarding particle velocities and the specific conditions of the magnetic mirror setup.

A gas composed of nuclear fuel is undergoing fission, producing fast moving positive ions that I wish to remove from the system by use of a magnetic mirror. What field strength is needed to ensure the fragments follow the trajectory I need, and not interact with the surrounding material?

That all depends on the velocity and mass of the particles. Along with the charge to mass ratio.
 
The average charge of the particles is +22, and the average masses are 140amu and 95amu.
 
Wish I could help you, but I don't know the math and details behind this. Try posting in the Nuclear Engineering forum and see if you get any help.
