In the case of DPF, I see the 400keV electron temperature as a bad thing since it leads to excessive bremsstrahlung radiation losses. The key will be if the proportion of energy going to raise the electron temperature can be limited enough with the switch to p-B11 fuel.

actually, seeing these 400 keV electrons represents a good opportunity to test and quantify the magnetic field effect. gigagauss fields should suppress them. so just how powerful is the effect?
