CONCLUSIONS

The MHD stability modelling for the experimental high amperage 500 kA cells
indicates that the selective collector bar rodding can be useful for reducing the cell noise and
increasing the stability. The effect may be particularly useful for the end of line cells where
the stability is often compromised.
