Very nice!
I see you noted the magnet current at 280A. Just purely out
of curiosity, because I love numbers like this, do you happen
to know the inductance?
Our little 400 MHz NMR is 38 henrys, a figure that sort of
gobsmacks me given that it's achieved without the help of
a ferromagnetic core (yeah, I know - lots and lots of turns,
but still...) At 95A, that works out to a bit over 170 kJ of
field energy. I'd be interested to know by what large factor
a behemoth such as yours dwarfs this.
