"Nothing. But the cyc magnet is a double pole affair. We could break the frame at the D plates and set one winding sidewise to the other and use half on each direction." "Sure. Have one of Warren's gang fit the busted pole pieces up with a return-magnetic frame so that the field will be complete. He can weld some girders on and around in an hour. That gives us complete deflection properties left and right; up and down. We should be able to cover a ninety-degree cone from your turret." "That'll cover all of Murdoch's ships," said Walt. "Too bad we haven't got some U_{235} to use. I'd like to plate up one of his ships with some positive ions of U_{235} and then change the beam to slow neutrons. That might deter him from his life of crime." "Variations, he wants," said Arden. "You're going to impale one ship on a beam of electrons, one ship on a beam of U_{235} ions; and what will you have on the third?" "I'll think of something," said Channing. "A couple of pounds of U_{235} should make things hum, though." "More like making them disappear," said Franks. "_Swoosh!_ No ship. Just an incandescent mass falling into the Sun. I'm glad we haven't got U_{235} in any quantity out here. We catch a few slow neutrons now and then, and I wouldn't be able to sleep nights. The things just sort of wander right through the Station as though it weren't here at all; they stop just long enough to register on the counter upstairs and then they're gone." "Well, to work, people. We've got a job to do in the next three and a half days." * * * * *
