In the image of the discharge you can clearly see that the device has no cladding. That means a discharge would be limited to a duration of a few seconds, otherwise the material ablated from the wall would lead to extreme heat losses of the plasma. Did they include a future vessel cladding to the plasma volume calculation in the article?

Good points and questions. First wall interaction is going to be an interesting problem for this team to work around.
