'He thinks we ought to bargain my work away. Why does the President keep him?'
'Ernie knows how to deal with the Russians, and he's a pro. He doesn't let personal opinions interfere with his job. I honestly don't know what he thinks about the issues. It's like with a doc. A surgeon doesn't have to like you personally. He just has to fix whatever's wrong. With Mr. Alien, well, he knows how to sit through all the crap that the negotiations entail. You've never learned anything about that, have you?' Jack shook his head and smiled at the traffic. 'Everybody thinks it's dramatic, but it's not. I've never seen anything more boring. Both sides say exactly the same thing for hours-they repeat themselves about every fifteen or twenty minutes, all day, every day. Then after a week or so, one side or the other makes a small change, and keeps repeating that for hours. The other side checks with its capital, and makes a small change of its own, and keeps repeating that. It goes on and on that way for weeks, months, sometimes years. But Uncle Ernie is good at it. He finds it exciting. Personally, after about a week, I'd be willing to start a war just to put an end to the negotiation process' — another laugh-'don't quote me on that. It's about as exciting as watching paint dry, tedious as hell, but it's important and it takes a special kind of mind to do it. Ernie's a dry, crusty old bastard, but he knows how to get the job done.'
'General Parks says that he wants to shut us down.'
'Hell, Major, you can ask the man. I wouldn't mind finding out myself.' Jack turned off Pennsylvania Avenue, following the CIA limousine. Five minutes later, he and Gregory were sitting in the west wing's reception room under a copy of the famous painting of Washington crossing the Delaware while the Judge was talking to the President's national security advisor, Jeffrey Pelt. The President was finishing up a session with the Secretary of Commerce. Finally, a Secret Service agent called to them and led the way through the corridors.
As with TV studio sets, the Oval Office is smaller than most people expect. Ryan and Gregory were directed to a small sofa along the north wall. Neither man sat down yet; the President was standing by his desk. Ryan noted that Gregory appeared a little pale now, and remembered his own first time here. Even White House insiders would occasionally admit to being intimidated by this room and the power it contained.
'Hello again, Jack!' The President strode over to take his hand. 'And you must be the famous Major Gregory.'
'Yes, sir.' Gregory nearly strangled on that, and had to clear his throat. 'I mean, yes, Mr. President.'
'Relax, sit down. You want some coffee?' He waved to a tray on the corner of his desk. Gregory's eyes nearly bugged out when the President got him a cup. Ryan did his best to suppress a smile. The man who'd made the presidency 'imperial' again-whatever that meant-was a genius for putting people at ease. Or appearing to, Jack corrected himself. The coffee routine often made them even more uneasy, and maybe that was no accident. 'Major, I've heard some great things about you and your work. The General says you're his brightest star.' Parks shifted in his chair at that. The President sat down next to Jeff Pelt. 'Okay, let's get started.'
Ryan opened his portfolio and set a photograph on the low table. Next came a diagram. 'Mr. President, this is a satellite shot of what we call sites Bach and Mozart. They're on a mountain southeast of the city of Dushanbe in the Tadzhik Soviet Socialist Republic, about seventy miles from the Afghan border. The mountain is about seventy- six hundred feet high. We've had it under surveillance for the past two years. This one'-another photo went down-'is Sary Shagan. The Russians have had ballistic-missile-defense work going on here for the past thirty years. This site right here is believed to be a laser test range. We believe that the Russians made a major breakthrough in laser power here two years ago. They then changed the activity at Bach to accommodate it. Last week they ran what was probably a full-power test. 'This array here at Bach is a laser transmitter.'
'And they blasted a satellite with it?' Jeff Pelt asked. 'Yes, sir,' Major Gregory answered. 'They 'slagged it down,' as we say at the lab. They pumped enough energy into it to, well, to melt some of the metal and destroy the solar power cells entirely.'
'We can't do that yet?' the President asked Gregory.
'No, sir. We can't put that much power out the front end.'
'How is it that they got ahead of us? We're putting a lot of money into lasers, aren't we, General?'
Parks was uncomfortable with the recent developments, but his voice was dispassionate. 'So are the Russians, Mr. President. They've made quite a few leaps because of their efforts in fusion. They've been investing in high-energy physics research for years as part of an effort to get fusion-power reactors. About fifteen years ago that effort was mated with their missile-defense program. If you put that much time and effort into basic research, you can expect a return, and they've gotten plenty. They invented the RFQ-the radio-frequency quadrapole-that we use in our neutral-particle beam experiments. They invented the Tokamak magnetic-containment device that we copied up at Princeton, and they invented the Gyrotron. Those are three major breakthroughs in high-energy physics that we know about. We've used some of them in our own SDI research, and it's for sure that they've figured out the same applications.'
'Okay, what do we know about this test they ran?' It was Gregory's turn again. 'Sir, we know that it came from Dushanbe because the only other high-energy laser sites, at Sary Shagan and Semipalatinsk, were under the visible horizon-I mean, they couldn't see the satellite from there. We know that it wasn't an infrared laser, because the beam would have been seen by the sensors on the Cobra Belle aircraft. If I had to guess, sir, I'd say that the system uses the free-electron laser-'
'It does,' Judge Moore noted. 'We just confirmed that.'
'That's the one we're working on at Tea Clipper. It seems to offer the best potential for weapons applications.'
'Can I ask why, Major?' the President asked.
'Power efficiency, sir. The actual lasing occurs in a stream of free electrons-that means they're not attached to atoms like they usually are, sir-in a vacuum. You use a linear accelerator to produce a stream of the electrons and shoot them into the cavity, which has a low-energy laser shining along its axis. The idea is that you can use electromagnets to oscillate the electrons crosswise to their path. What you get is a beam of light coincident with the oscillation frequency of the wiggler magnets-that means you can tune it, sir, like a radio. By altering the energy of the beam, you can select the exact light frequency you generate. Then you can recycle the electrons back into the linear accelerator and shoot them back into the lasing cavity again. Since the electrons are already in a high- energy state, you gain a lot of power efficiency right there. The bottom line, sir, is that you can theoretically pump out forty percent of the energy you pump in. If you can achieve that reliably, you can kill anything you can see-when we talk about high energy levels, sir, we're speaking in relative terms. Compared to the electrical power that this country uses to cook food, the amount needed for a laser defense system is negligible. The trick is making it really work. We haven't done that yet.'
'Why not?' The President was interested now, leaning forward slightly in his chair.
'We're still learning how to make the laser work, sir. The fundamental problem is in the lasing cavity-that's where the energy comes off the electrons and turns into a beam of light. We haven't been able yet to make a very wide one. If the cavity is too narrow, then you have such a high power density that you fry the optical coatings both in the cavity itself and on the mirrors that you use to aim the beam.'
'But they've beaten the problem. How do you think they i did it?'
'I know what we're trying to do. As you draw energy into the laser beam, the electrons become less energetic, okay? That means you have to taper the magnetic field that contains them-and remember that at the same time you have to continue the wiggling action of the field, too. We haven't figured that out yet. Probably they have, and that probably came from their research into fusion power. All the ideas for getting energy out of controlled fusion are concerned with using a magnetic field to contain a mass of high-energy plasma-in principle the same thing we're trying to do with the free electrons. Most of the basic research in that field comes from Russia, sir. They're ahead of us because they've spent more time and money in the most important place.'
'Okay, thank you, Major.' The President turned to Judge Moore. 'Arthur, what does CIA think?'
'Well, we're not going to disagree with Major Gregory-he just spent a day briefing our Science and Technology people. We have confirmed that the Soviets do have six free-electron lasers at this place. They have made a breakthrough in power output and we're trying to find out exactly what the breakthrough was.'
'Can you do that?' General Parks asked.
'I said we're trying, General. If we're very lucky, we'll have an answer by the end of the month.'
'Okay, we know they can build a very powerful laser,' the President said. 'Next question: is it a weapon?'
'Probably not, Mr. President,' General Parks said. 'At least not yet. They still have a problem with thermal blooming because they haven't learned how to copy our adaptive optics. They've gotten a lot of technology from the
