ITER operation

I am told (see, for example, Hollow current profile scenarios for advanced ITER operation, P. Gourdain and J. Leboeuf, researchgate.net, 19 Mar 2014) that the international thermonuclear experimental reactor (ITER) is to use hollow current profile (R. Jones, Nuovo Cimento, 40B, pg 303, 1977  and R. Jones, Can. J. Physics, vol 57, pg 635, 1979) to achieve high performance.
