The electrons execute tightly spiralled orbits around the wire and produce synchrotron radiation as their orbit radius decreases. These are an incredibly simple broadband microwave source consisting of a very thin wire, about 10 um diameter, that is held along the central axis of an evacuated cylinder.Ī high potential is applied between the wire and cylinder causing electrons to be emitted from the wall of the cylinder and then accelerate towards the wire. An accumulation of energy by resonance avoids this problem, up to a certain limit.īack in 2006 I did some research into creating a coherent terahertz source using a modified "Orbitron" for one of our customers. dV/dt which can be enormous at high dV/dt and hence high frequency). Note: it is extremely difficult (let's see almost impossible) to produce high voltage at high frequencies (lets's say >10 MHz) due to the parasitic capacity (the power P to load this capacity being in P=C. This device has no magnetic confinement so the efficiency would be probably similar to the Fusor one or a bit better. In another configuration, it can also be coated with boron to produce B11+ H+ fusions. The antenna tip is coated with Lithium to breed the reactor in T+ ions. The RF frequency is supposed to create a periodically oscillating plasma with ions increasing their speed by accumulation of energy (possible even if the electric field is low). In a bell jar under vacuum, it is injected a Deuterium gas.
they create a RF resonance with a magnetron (RF generator) and a wave guide (to limit RF losses), so that the secondary electrons multiplication be sufficient to lead to an exponential growing of electrons flow which is a sort of "avalanche" of electrons.Ībout their invention regarding the "Multipator fusor device, I abstract their interesting idea for the ones not having read the patent (and for what I understand, as it is not absolutly clear).Ī magnetron supplies with RF a central tuned antenna so as to create a RF oscillating electric field. For what I understand (but I'm not too sure), the term "avalanche" might refer to their invention regarding the "plasma generation system" where they use their system to use the "Multipactor effect", i.e.
