Key takeaway here is novel fast neutron generators [1] that are flat and electronically modulated, so they are potentially good for data transmission through metallic vessels (ship hulls for example) that doesn't require vessel penetration and isn't heavily regulated like californium isotopes.
The researchers wanted to demonstrate the data transmission in practice, but used a more conventional setup instead (a Cf-252 source mechanically modulated by a HDPE slab).

- irq 5y ago> electronically modulated Is it really electronic modulation when the modulation is handled by pneumatically moving a polyethylene block? I would call that mechanically modulated. Electronic modulation would be, say, a transistor switching the output on/off.
- orbital-decay 5y ago[1] in the post above links to a different paper (referenced in OP), which describes exactly that. The researchers in the OP used mechanical modulation instead (which is far less interesting)
- hasmanean 5y agoCould they have used a Farnsworth fusor as a neutron source and electrically modulated it at radio frequencies?
