The third insulator passed on day 1093.
Tena Voss let it cool after the hot separation trial, examined it under the angled lamp and repeated the edge test. The mark she put on its cover was small. It did not look large enough for the days of firing, waiting and starting again that had made it possible.
On the morning of day 1094, the bank crew brought it through the guarded door.
Iven stood beside Rask at the open central bus. He had three hundred and ninety charges in reserve beneath his measured maximum of four hundred and six, five channels and twenty-five physical patterns. No part of the storage bank had entered that library while it stood broken. The sound isolated cell he had watched weeks earlier had demonstrated a function; watching it had not given him one.
Today they had a complete set of sound parts and a chance to restore the actual assembly.
Tena read the isolation sequence with the operator who would run the bank after the visitors left. Each cell group had its own present state on the board. The drive was stopped. The retained energy was discharged into its rated receivers or secured behind the appropriate separation. The accessible work did not rely on everybody remembering that a dark lamp might still have a live supply behind it.
