And a glowing neon lamp contains a plasma, but this is a world away from fusion capable plasma conditions.
Ignoring for a minute the impossibility of having a spherically symmetric pressure on the walls – your diagram shows the outer shell containing water at ~250bar. To contain this the wall would have to be many inches of steel, or similar. You then propose heating the core using microwaves. How are the microwaves supposed to travel through the containing wall and water?? In order to couple and heat a plasma an RF antenna must be within a few ion skin depths of the plasma, otherwise it is just reflected back.
