Session 6: Questions for the discussion

[mariomerinomartinez]

As chairmen of session 6, Justin and I want to know what you think of the questions we have highlighted for the discussion (i.e. second part of the session), and whether you would have anything to add. You can check the slides here. The questions so far are:

• What is the trapped electrons population in a magnetized/unmagnetized plume?
• How sensitive this population is to collisionality, initial transient, etc?
• What experiments can be designed to study electrons kinetically, in particular the trapped population?
• What is the degree of freedom of electrons and ions in magnetic nozzle device
• Proper closures at pressure level and heat flux level: simplified electron cooling models
• How can kinetic studies help obtain proper closures?
• How can experiments be designed for obtaining proper closures?
• Oscillations in the magnetic nozzle and their relation to perpendicular transport?
• Ranges of frequencies, mechanisms involved.
• What models/simulations to carry out?
• What experiments to design?
• Electron detachment. What mechanisms are at play? How to characterize it numerically and experimentally?
• What is the effect of charged obstacles on the performance of magnetic nozzles?
• What boundary conditions for the electron fluid downstream? Local vs global conditions, which ones enable the
  smallest simulation domain?
