追踪了好幾編文章. 似乎此人的EXPERIEMENTAL REACTOR 該是用
DEUTERIUM TYPE ( 也叫 2-H ) 重氫聚變型, D ...
而有關安全性問題, 看他的訪問:
I then proceeded to collect parts, design and build a demonstration fusor: essentially a fusor lacking a system to create a deuterium (hydrogen-2) atmosphere. This does everything a "fusing" fusor does, however in an atmosphere consisting of a gas other than deuterium.
Q. What types of radiation do you need to be concerned about?
A. When operating a fusor, you need to be aware of two types of radiation: fast neutron radiation caused by the fusion reaction, and bremsstrahlung x-ray radiation caused by the slowing down of electrons. The primary cause for concern is the x-ray hazard, X-rays will begin to shine through viewports and other glass surfaces at around 12,000 volts of input voltage (this is why cameras and mirrors are used to look through viewports), and they will begin to penetrate stainless steel at around 40,000 volts. At the point that they begin to shine through anything, it is wise to shield that area with lead. Generally for most fusors, neutrons are not typically a worry unless you run your reactor to the point where it emits multiple hundreds of thousands of neutrons per second. At that point, it is usually wise to shield the fusor with a shield made of parrafin wax or boron dissolved in water.
Radiation is not a dangerous aspect of operating a fusor is ordinary circumstances for a number of reasons. First is that the radiation is emitted isotropically, in other words, in all directions. This means that as you get farther from the fusor, the radiation strength drops with the square of the distance from it. This means that you only have to be a few feet from the fusor to minimize your radiation dose.
Another factor contributing to the safety of the fusor is that they are typically run for only a short period of time, as they are rather "finicky" to operate. Most people do less than an hour high power fusion every month. Thus minimizing radiation exposure.
Q. Have you taken radiation measurements and confirmed that the fusion reaction occurred during operation?
A. My fusor is currently only a demonstration fusor, and as I explained above, no detectable fusion reactions are occurring. HOWEVER, My current project is the rebuild of my demonstration fusor into a fusing fusor complete with DC magnetron Ion source, 50,000 volt power supply, deuterium system, and ultra-high vacuum system |
