into a grin that made him look grandfatherly, a kindly elder statesman. "I would like, therefore, to have
him explain how this . . . ah, weapon, can be an exhibit in the matter before our committee."
Wallace glanced at Custer, saw the hard set to the man"s jaw, realized the cattleman had gotten to Plowers somehow. This was a set piece.
Tiborough was glancing at the other senators, weighing the advisability of high-handed dismissal . . . perhaps a star chamber session. No . . . they were all too curious about Custer"s device, his purpose here.
The thoughts were plain on the Senator"s face.
"Very well," Tiborough said. He nodded to Custer. "You may proceed, Mr. Custer."
"During last winter"s slack season," Custer said, "two of my men and I worked on a project we"ve had in the works for three years-to develop a sustained-emission laser device."
Custer opened his briefcase, slid out a fat aluminum tube mounted on a pistol grip with a conventional
appearing trigger.
"This is quite harmless," he said. "I didn"t bring the power pack."
"That is . . . this is your weapon?" Tiborough asked.
"Calling this a weapon is misleading," Custer said. "The term limits and oversimplifies. This is also a
brush-cutter, a subst.i.tute for a logger"s saw and axe, a diamond cutter, a milling machine . . . and a weapon. It is also a turning point in history."
"Come now, isn"t that a bit pretentious?" Tiborough asked.
"We tend to think of history as something old and slow," Custer said. "But history is, as a matter of fact, extremely rapid and immediate. A President is a.s.sa.s.sinated, a bomb explodes over a city, a dam breaks, a revolutionary device is announced."
"Lasers have been known for quite a few years," Tiborough said. He looked at the papers the Colonel
had given him. "The principle dates from 1956 or thereabouts."
"I don"t wish it to appear that I"m taking credit for inventing this device," Custer said. "Nor am I claiming sole credit for developing the sustained-emission laser. I was merely one of a team. But I do hold the device here in my hand, gentlemen."
"Exhibit, Mr. Custer," Plowers reminded him. "How is this an exhibit?"
"May I explain first how it works?" Custer asked. "That will make the rest of my statement much easier."
Tiborough looked at Plowers, back to Custer. "If you will tie this all together, Mr. Custer," Tiborough
said. "I want to . . . the bearing of this device on our-we are hearing a particular bill in this room."
"Certainly, Senator," Custer said. He looked at his device. "A ninety-volt radio battery drives this particular model. We have some that require less voltage, some that use more. We aimed for a construction with simple parts. Our crystals are common quartz. We shattered them by bringing them to
a boil in water and then plunging them into ice water . . . repeatedly. We chose twenty pieces of very close to the same size-about one gram, slightly more than fifteen grains each."
Custer unscrewed the back of the tube, slid out a round length of plastic trailing lengths of red, green,
brown, blue and yellow wire.
Wallace noted how the cameras of the TV men were centered on the object in Custer"s hands. Even the senators were leaning forward, staring.
We"re gadget-crazy people, Wallace thought.
"The crystals were dipped in thinned household cement and then into iron filings," Custer said. "We
made a little jig out of a fly-tying vise and opened a pa.s.sage in the filings at opposite ends of the crystals. We then made some common celluloid-nitrocellulose, acetic acid, gelatin, and alcohol-all very common products, and formed it in a length of garden hose just long enough to take the crystals end to end. The crystals were inserted in the hose, the celluloid poured over them and the whole thing was seated in a magnetic waveguide while the celluloid was cooling. This centered and aligned the crystals. The waveguide was constructed from wire salvaged from an old TV set and built following the directions in the Radio Amateur"s Handbook."
Custer re-inserted the length of plastic into the tube, adjusted the wires. There was an unearthly silence
in the room with only the cameras whirring. It was as though everyone were holding his breath.
"A laser requires a resonant cavity, but that"s complicated," Custer said. "Instead, we wound two layers of fine copper wire around our tube, immersed it in the celluloid solution to coat it and then filed one end flat. This end took a piece of mirror cut to fit. We then pressed a number eight embroidery needle at right angles into the mirror end of the tube until it touched the side of the number one crystal."
Custer cleared his throat.
Two of the senators leaned back. Plowers coughed. Tiborough glanced at the banks of TV cameras and there was a questioning look in his eyes.
"We then determined the master frequency of our crystal series," Custer said. "We used a test signal and
oscilloscope, but any radio amateur could do it without the oscilloscope. We constructed an oscillator of that master frequency, attached it at the needle and a bare spot sc.r.a.ped in the opposite edge of the waveguide."
"And this . . . ah . . . worked?" Tiborough asked.
"No." Custer shook his head. "When we fed power through a voltage multiplier into the system we
produced an estimated four hundred joules emission and melted half the tube. So we started all over again."
"You are going to tie this in?" Tiborough asked. He frowned at the papers in his hands, glanced toward
the door where the colonel had gone.
"I am, sir, believe me," Custer said.
"Very well, then," Tiborough said.
"So we started all over again," Custer said. "But for the second celluloid dip we added bis.m.u.th-a
saturate solution, actually. It stayed gummy and we had to paint over it with a sealing coat of the straight celluloid. We then coupled this bis.m.u.th layer through a pulse circuit so that it was bathed in a counter wave-180 degrees out of phase with the master frequency. We had, in effect, immersed the unit in a thermoelectric cooler that exactly countered the heat production. A thin beam issued from the unmirrored end when we powered it. We have yet to find something that thin beam cannot cut."
"Diamonds?" Tiborough asked.
"Powered by less than two hundred volts, this device could cut our planet in half like a ripe tomato,"
Custer said. "One man could destroy an aerial armada with it, knock down ICBMs before they touched
atmosphere, sink a fleet, pulverize a city. I"m afraid, sir, that I haven"t mentally catalogued all the violent implications of this device. The mind tends to boggle at the enormous power focused in. . . ."
"Shut down those TV cameras!"
It was Tiborough shouting, leaping to his feet and making a sweeping gesture to include the banks of
cameras. The abrupt violence of his voice and gesture fell on the room like an explosion. "Guards!" he called. "You there at the door. Cordon off that door and don"t let anyone out who heard this fool!" He whirled back to face Custer. "You irresponsible idiot!"
"I"m afraid, Senator," Custer said, "that you"re locking the barn door many weeks too late."
For a long minute of silence Tiborough glared at Custer. Then: "You did this deliberately, eh?"
"Senator, if I"d waited any longer, there might have been no hope for us at all."
Tiborough sat back in his chair, still keeping his attention fastened on Custer. Plowers and Johnstone on his right had their heads close together whispering fiercely. The other senators were dividing their
attention between Custer and Tiborough, their eyes wide and with no attempt to conceal their astonishment.
Wallace, growing conscious of the implications in what Custer had said, tried to wet his lips with his
tongue. Christ! he thought. This stupid cowpoke has sold us all down the river!
Tiborough signaled an aide, spoke briefly with him, beckoned the colonel from the door. There was a buzzing of excited conversation in the room. Several of the press and TV crew were huddled near the windows on Custer"s left, arguing. One of their number-a florid-faced man with gray hair and horn-
rimmed gla.s.ses-started across the room toward Tiborough, was stopped by a committee aide. They began a low-voiced argument with violent gestures.
A loud curse sounded from the door. Poxman, the syndicated columnist, was trying to push past the
guards there.
