I always wondered, whether a transformer would be a good idea.
So for example an 6-times step-down transformer as used in the paper would yield 4000-times increase of neutron yield with the same input power:
U_effective = U_input / 6
I_effective = 6 * I_input
P_input = U_input * I_input = U_effective * I_effective
N_n = const * I_effective ^ 4.7 = const * (6 * I_input) ^ 4.7 = const * 4542 * I_input ^ 4.7
But then I know that one of the goals is to reduce inductance (read it somewhere in Eric’s early papers on arXiv), to enable fast rise-time of the current, which seems to be crucial. I always thought a transformer will add inductance.
But as Bures et al. write, on the secondary side of the transformer, induction and resistance will be reduced 36-fold (with a 6-times step-down transformer). Someone with more electrical engineering background should take a look at that paper.
BTW: Dr. John Thompson (mentioned in the paper) also (co-)designed LPP’s DPF, see this Link.
