Re: Viable design?

... you considered the the Paschen Curve and determining the necessary parameters relating breakdown voltage, pressure, and gas fill? Note also the safety considerations - arcing through deuterium can create explosive conditions if there is any air remaining in the chamber. Have you considered the ...

... as well. It is very easy to place a camera in front of the viewport and then shield the surrounding area. Can you elaborate on your shielding/safety precautions during fusion runs? Congrats on fusion and great effort so far. -Scott Moroch

Re: High Vacuum Engineering Design, Analysis, and Build of a Small-Scale Multipurpose System

... speed still, and as such, a backing pump has been selected with a displacement of 2.83 L/s, much more than is required for this system with a good safety margin. This should allow me to still attain 600 L/s at the pump inlet, while having additional overhead. Because the actual gas load will be ...

Re: Has anyone used the Spellman X3000 50V-30kV 400uA Rev E7 24Vdc

... current (with voltage) also determines the input power, is there a power rating that is best suited for "wall plug" use without compromising on safety?

Re: Double-Checking Diffusion Pump before Buying

... most probable to attain at the lowest prices. Even with all this planning, I am now on my fourth design iteration for my chamber, and my margin of safety for cost is slowly evaporating. It's another reason why I decided to spend my free time doing calculations and cad for my system, as well as ...

Re: Small Scale Multi-Purpose High Vacuum Chamber

... the pressure at the inlet. The recommended CFM for my diff pump is 4CFM, however I am going with an 8CFM 2 stage backing pump for an extra bit of safety factor. In regards to the calculations, so far I have completed the calculations for characterizing the pipeline conductance as well as effective ...

Re: Matsusada Power Supply Cable

... This avoids arcs inside the tightly packed electronics in the all metal rack mount box. Once voltages soar to above 20kv in a power supply, modern safety codes demand a fully contained metal, grounding enclosure. The higher the voltage, the larger the enclosure and the more bizarre and taxing become ...

Re: X radiation exposition

... regardless of the x-rays. Use only HV proper cables rated to at least 50 kV and be certain any fusor is properly grounded - read the FAQ's on the safety of high voltage for fusors (NEVER allow your transformer to float!) I use shielded/grounded high voltage cables to be certain my system is safe. ...
