what did we miss?

many measurements are absent from the work, mostly because it was difficult with technology of that period, and because the budget was very limited.  measurements they could make required instruments which were slow to operate, so short slices of time went unseen.  these experiments were not long in duration, dynamic in nature, and the ability to quantify events which were dynamic and short in nature, was missing.  these short events would have been the only beacon to guide the progress of the research.    
events which were secondary, but very significant do not show up in anything I have read, anywhere.

we have ions entering the cathode space traveling only a fraction of the velocity of particles which result from a fusion, what happens when a neutron traveling at velocity about 14 times that of incoming ions, hits an ion, or an atom of He3 or He4?

i suppose it is only the bottom line matters, no matter how the fusion is caused, as long as they happen.
