| > the intensity of neutron radiation at the first wall is far too low for a viable commercial reactor Source? Proofs? Sorry, for me this looking as just Your opinion. > Second, ITER cannot operate for more than a few weeks This is just not important at all now. That what I mean, said You don't understand physics. - NOWHERE at Earth possible to recreate exact radiation environment of Jupiter orbit for YEARS, need to test radiation capable computer environment for space probes. What really doing? After first probes measured parameters of environment, at Earth built test benches, consisting of few throttle-able sources, so they give approximate spectrum, very like near Jupiter, but could do year dose in few hours and could easy be switched off, to make manipulations with tested samples. So now, I even know guys, who touched exposed chips and running real world software on them, and real computers in Jupiter/Mars missions, working much longer than need for mission (BTW, first samples tested at Earth, where not reliable). |
