Joe's ex-lover Simon, an industrial designer, designs the case for the PC, which is named the "Cardiff Giant". Initially hesitant about the project, Bosworth comes around but is denied further funding by Cardiff. With Cameron's help, Bosworth embezzles money to sustain the project but is arrested as the company office is raided by the FBI. Having smuggled out the Giant prototype, Gordon convinces the others to proceed with their plan to present at the COMDEX trade show. In 1983, former IBM sales executive Joe MacMillan joins Cardiff Electric, a Dallas-based mainframe software company.
A 100 kW/kg reactor, 250 W/kg emitter-laser stack and 3.73 kW/kg radiators would mean an overall power density of 188 W/kg, after applying the penalty. Instead, researchers have come up with a way to recover the 99 to 99.9% of the blackbody spectrum that the lasing medium does not use. The most straightforward way of creating a nuclear reactor laser is to have fission products interact directly with a lasing medium.
Series synopsis
The agency is requesting $304 million to bring several missile defense technology projects to maturation, including lasers and NPB. Lasers are less efficient than particle beams due to the necessity of converting electrical energy into thermal/optical energy. After some point, the beam energy is reduced by such a degree that it will emit a different wavelength, but due to the beam also passing through our accelerator we can add the energy back each time. Tactics around using lasers and counter-lasers, something called ‘eyeball-frying contests’ can sometimes lead to a large and powerful warship being brought to a stalemate by a small counter-laser. Unlike a rocket engine, we cannot have a hydrogen propellant absorb waste heat and release it through a nozzle. The NASA reference was designed around reducing waste heat to remove the need for radiators, but we will need them.
This beam would cross a distance of 1,000 km in about fifty milliseconds and would remain focused within a spot just 8.1 cm wide. For example, a lithium atom would release a photon with an energy of 5.39 eV and a Cesium atom would release photons with an energy of 3.89 eV. Any division of these energies would correspond to visible wavelengths. This divergence is to be added to that of the beam before neutralization. In the real world, the neutralization disturbance will be greater than the theoretical minimum. The latest option being developed is neutralization by lasers, also called photo-neutralization.

When Joe supports the decision, a heartbroken Cameron leaves him. Joe and Gordon present the downgraded Giant at COMDEX and secure their first order, but it's a hollow victory for the team. After witnessing a demonstration of the Apple Macintosh at the conference, Joe becomes disillusioned with the Giant. Cameron quits Cardiff Electric and poaches most of the software engineers to form an online gaming startup company called Mutiny.
This technology may achieve high excitation rates with small laser volumes. A cylindrical package five centimeters long by five centimeters in radius would be packed with 20,000 lasing needles 25 µ diameter by 5 centimeters long (I assume that µ means micrometre or micron). The needles would be composed of Lithium-7 with 0.025% Tantalum-180. The needles would be aligned in parallel with 100 µ spacing between their axes, and arranges so that the centers of no three needles would be in a straight line. The x-rays are then self-amplified through spontaneous emission.

So the problem comes down to efficiently accelerating the electron beam. Since laser beams move at the speed of light, it is actually impossible to dodge a laser unless you are always dodging. This is because the speed of light is the speed at which information travels in the universe. Thus, you can never determine where a laser will be until it actually hits you. This would be impossibly overpowered in warfare were it not for diffraction. One might point out that the laser has to be focused by a mirror, and that the same mirror should be capable of being used as armor.
The beam power or energy requires could in principle be determined for a given engagement scenario — engagement time and distance; target size and armor. This will, of course, depend on the tech choices made elsewhere in the setting, so no single value can be quoted. Longer ranges, shorter engagement times, or more massive or more heavily armored ships all tilt you toward needing more beam power. It might also be possible to use the instantaneous response of the phased array to correct for some of the vibration inherent in a laserstar, above and beyond what is possible with conventional mirrors. First, each element can probably be isolated individually, making the system smaller and lighter, and quite possibly more effective. Second, the phased array can be used to compensate for vibration with greater accuracy then adaptive optics, due to the electronic pointing capabilities.

Now, what if the electron beam was a particle beam weapon and the metal target was the hull of the enemy spacecraft? A hypothetical observer on the far side of the ship could make a nifty x-ray photo revealing the skeletons of crew members dying in agony of radiation poisoning. While particles cannot travel at the speed of light, they can get close enough that it is hard to tell the difference. A fusion rocket that uses macron propulsion enjoys many of these advantages too. A kinetic impactor can concentrate the output of an ignition mechanism like an ion beam from a particle accelerator from several milliseconds to less than a nanosecond.
It is possible to neutralize the beam by adding electrons to accelerated nuclei, or subtracting electrons from negative ions. The particle beam weapons postulated for Star Wars missile defense were to disable missiles by damaging the sensitive electronics via radiation, not by carving the missiles into pieces. An APS directed-energy weapons study written for the Strategic Defense Initiative estimated that in order to disable an ICBM, a particle beam had power requirements between 100 and 1,000 megawatts, depending on range and retargeting rate. This is a weird idea I had a couple years ago, which is basically an unusual alternative to lasers for a long range beam. Normally, electron beams are not considered suitable for long range due to self repulsion. A beam that starts off narrow will bloom outward because the electrons repel each other.
The increased voltage gradient means that 100 MV only needs between 10 and 100 meters of length. The most powerful electrostatic accelerators are for nuclear research purposes. They operate at several megavolts and are used to accelerate electrons and ions. Smaller warships would have a bigger proportion of their mass dedicated to shielding, making them less effective on a ton per ton basis compared to larger warships. The smallest vehicles suffer the most, with cheap massed missile swarms becoming irrelevant due to the ability of a radiation beam to disable them in seconds. Deploying a more penetrating beam due to technological advances could suddenly render older warships with insufficient shielding obsolete.

Most surface-based lasers get their performance in a similar manner, as the horizon forces them to fight at close range. A spacecraft, however, does not normally have a horizon to hide behind and much use much larger mirrors and much higher power to deal damage at long range. This produces a fundamentally difference in character between laser engagements on the surface and in space. On the surface, laser battles are over almost instantly, as one side or the other gets the first shot in. In deep space, long lines of sight allow both sides to open fire as soon as they could begin doing damage, slowing the battle down. If the craft did close to point-blank range, their lasers would become incredibly lethal, but both sides would be aware of this and probably avoid tactical geometries that lead to such situations.
In other words, it is pointless for relativistic particle beam weapons to use antimatter, with all the added complexity due to antimatter manufacture and storage. If we keep the beam energy the same, but the spot height is inversely proportional to the amperage. In other words, if we keep the beam velocity the same but change the power, spot height is inversely proportional to power. If we increase the beam energy , but keep the power the same, amperage is reduced but fanning width is also reduced by the square root of the beam energy. The overall effect that spot height is inversely proportional to the square root of the beam energy . But using the ambient magnetic field, it's possible to do something completely different.

Self-produced by the network and mostly filmed in the Atlanta, Georgia area, the series is set in the Silicon Prairie for its first two seasons and Silicon Valley for its latter two. Halt and Catch Fire is an American period drama television series created by Christopher Cantwell and Christopher C. Rogers. It aired on the cable network AMC in the United States from June 1, 2014, to October 14, 2017, spanning four seasons and 40 episodes. It depicts a fictionalized insider's view of the personal computer revolution of the 1980s and the early days of the World Wide Web in the early 1990s.
The ions are forced to orbit within a small circle by magnetic fields so that they can be contained. However, the rotation within the magnetic fields adds a radial velocity to the ions. The result is an emittance dominated by the strength of the magnetic fields and the charge to mass ratio of the ions. In scientific literature, the divergence of a particle beam is rarely given or used. It is the result of multiplying the divergence of a beam by its radius to produce a measure in ‘meters-radians’.
