17. These ion energies are below the threshold for sputtering, ionization or secondary emission from the apposing electrode, lattice dislocation, or implantation. They are sufficient, however, to excite translational, rotational, vibrational modes, and, in principle, chemical reactions.
18. Ions tend to be trapped in the spool by gap fields, while neutrals can traverse the gap unimpeded.
19. This can be increased with dendritic surface finishing.
20. For instance, it might be the case that M1 produces intermediates that facilitate reactions on M2, irrespective of the gap electric field. Such processes would complicate verification of the IBEC effect.
21. Often the gas and surface temperatures will not equilibrate on the time scale of the experiment.
22. -3 have been demonstrated.
23. Important concerns surrounding the catalyst's structural integrity, lifetime, and poisoning are beyond the scope of this discussion.
24. One can view the gas ions in the J-II gap as performing a substitute role for the charge carriers in the J-I depletion region of the SSD. The gas J-II ions act to balance chemical and electrostatic potentials so as to establish a static, low-energy equilibrium state.
25. A buffer gas (e.g., He, Ar) might accelerate this purging process.
26. A catalyst cannot alter the chemical equilibrium of a reaction; it can only speed both forward and reverse reactions so as to achieve equilibrium more rapidly.
27. It is remarkable to consider that, in principle, one could casually handle a room temperature catalyst, belying its 10 000 K interior gas temperature.
