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 ...

... general group of people - especially a school. While certainly an appropriate and exciting area of science application in action, there are severe safety issues that must be carefully addressed. One must approach this device as a serious safety hazard - an operational fusor use's very high voltages ...

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. ...

Re: X radiation exposition

X radiation exposition

Hello, I’ve been doing some tests with my fusor earlier and I’m now worried about my own safety, I run this fusor on about 50 KV 10 miliamps in a vacuum about 1000 microns for about one minute at aproximatelly one meter of it, is there any formula I can use to determine ...

FAQ - X-rays, X-rays, X-rays....A tutorial

... it is true, no shielding is needed in most all situations regarding fusor operation. Use the inverse-square law as your first line of defense and safety regarding any source of radiation. It is worth 3,000 lbs of lead shielding any day. Now to the nitty-gritty of the x-ray tutorial Demo fusor ...

A nice Surplus item to make a Neutron Detector Power Supply

... but again, will save it. I will, this weekend, test the HV x-former system (after I add a bleed resistor to that cap! Always try and think about safety - another important point for people new to HV systems; one careless lapse in judgement can be fatal so try and think ahead and do the extra ...
