They plan to use 2D + 3He -> 4He + 1H, so no neutrons https://en.wikipedia.org/wiki/Aneutronic_fusion#Candidate_re...

(I'm still not convinced of their explanations, but a fast proton may be easy to catch by the magnetic field and create the effect they want.)

Nitpick: You’re always going to get some parasitic D+D reactions because it’s reaction cross section is appreciably higher than D + 3He below 50 keV, and non-negligible even after the crossover point.

Doesn't D+D just yield 4He (and no neutrons) though?

It yields 3He plus a 2.45 MeV neutron at least part of the time.
