Optimal placement of probes in magnetostatic reconstruction ‐ The case of plasma identification in Tokamaks

The applied research in the thermonuclear fusion area is directed towards the design of a commercial reactor. In such a reactor, the room required for the probes deputised to measure the magnetic field for the identification step of the control system must be kept to a minimum, and the number and position of probes must be optimised. A possible approach to the optimal choice of a set of magnetic probes for the reconstruction of a magnetostatic field, based on a statistical approach, is presented and discussed.
