ok....let me simplify this...1 the neutron generator , is a pipe tube, with heavy hydrogen (you can't find it, it looked like we have to prepare it ...) that has deuterium isotope (meaning the deuterium, will double the hydrogen energy blast) ...2. this heavy hydrogen, is inside the pipe, called ions source...3 the tritium is a solid target, between aluminium layers , where 4. a magnet will be high voltage discharge, to blast the (tritium) target...5 getting heavy hydrogen, in HDX (deuteraded hydrogen...the same thing) mass spectrometry device ...(or else has to be prepared...because the liquid hydrogen must be distillated until deuterium is enriched ) ...let see the images
