I do not think linear accelerators have ever been used in this way.
I talked with John Powell about the problem and he raised an obvious serious objection. If you heat the crystal high enough
so that ions can come off with a reasonable field, you will have melted the crystal. Also I would think that instead of C-
ions coming off, electrons would and leave either Cl or Cl2.
The meeting was certainly very profitable and I think one more should have us [ . . . ].
