To maximize efficiency of energy transfer, the density difference between layers should be minimized. The tamper or reflector might be designed to work as the pusher too, although a low density material is best for the pusher but a high density one for the tamper. It works by reflecting some of the shock wave backwards which has the effect of lengthening it. A pusher shell made out of low density metal such as aluminium, beryllium, or an alloy of the two metals (aluminium being easier and safer to shape but beryllium reflecting neutrons back into the core) may be needed and is located between the explosive lens and the tamper. The explosion shock wave might be of such short duration that only a fraction of the pit is compressed at any instant as it passes through it. If you're an electronics wiz, you should be able to make it using a cellphone. These detonation caps can be found in the electrical supply section of your local supermarket. With a modicum of effort, a remote plunger can be made that will strike a detonator cap to effect a small explosion. To fabricate a detonator for the device, get a radio controlled (RC) servo mechanism, as found in RC model airplanes and cars. Semtex would be good too, but it's a bit hard to get, these days. Gelignite (an explosive material consisting of collodion-cotton (a type of nitrocellulose or gun cotton) dissolved in nitroglycerine and mixed with wood pulp and sodium or potassium nitrate) would be better. The explosive to start the nuclear chain reactionġ00 pounds (44 kg) of trinitrotoluene (TNT). North Korea is not ready yet, and unfortunately, Iraqi dealers retired from the business.ī. You could try buying it from a former Soviet Republic, or from Iran, since they're trying so hard to produce it. To be used as the fissile core of a nuclear weapon, the uranium has to be enriched to more than 90 per cent and be produced in large quantities. The process is repeated many times over through a cascade of centrifuges to create uranium of the desired level of enrichment. The rotation causes a centrifugal force that leaves the heavier U-238 isotopes at the outside of the cylinder, while the lighter U-235 isotopes are left at the center. The uranium hexafluoride gas is piped in a cylinder, which is then spun at high speed. You would need to refine it using a gas centrifuge. If you could find some Uranium235, that would be good, but not great. Around 25 pounds (10 kg) would be enough.
Despite this possible confusion, the term atom bomb has still been generally accepted to refer specifically to nuclear weapons and most commonly to pure fission devices.
These are historically called atomic bombs, atom bombs, or A-bombs, though this name is not precise due to the fact that chemical reactions release energy from atomic bonds (excluding bonds between nuclei) and fusion is no less atomic than fission.
These newly liberated neutrons then bombard other nuclei, which then split and bombard other nuclei, and so on, creating a nuclear chain reaction which releases large amounts of energy. If not, you need to know on a first name basis some evil leader with lots of cash, oil, diamonds and so on, of a small but ambitious country, with a need for revenge on the world.įission bombs derive their power from nuclear fission, where heavy nuclei (uranium or plutonium) are bombarded by neutrons and split into lighter elements, more neutrons and energy. You need some money, as it would really help if you were the prince, sultan or other royalty of a small, but rich state. We will look today at what you need in order to make a nuclear fission bomb.
