... so it can be easily explained to a layperson. To meet the safety requirements the HV power must be restricted in voltage and current. There is of course only low vacuum rotary vane pump, and the fusor will ...

... a BBQ tank so old it still has a POL valve. Glad to be with Dennis on a safety thing! Am reminded of one classic HV high bandwidth scope probe: the ... it needed to be refilled. https://www.eevblog.com/forum/testgear/high-voltage-oscilloscope-probes-make-or-buy/ Amateurs have used butane as a replacement ...

... build a ~30Kv transformer with 0.03-0.04mA use a variac for control, a voltage divider to measure the voltage and string some cheap 20Kv diodes ... through issues/revisions so I waited. For anyone concerned with my safety, I DO OF COURSE plan on using NMN laminate paper for the insulation ...

... 2. 3D, 2D, and 1D Cathodes and the advantages in pressure, Neutrons, voltage and current based on geometry. Today I will share a Neutron generating ... welding put a brass brush on a dremel and brush the welds shiny. Wear safety goggles or you will lose an eye. Brass dremel brushes release brass ...

... try another “push to the limits test”, but this time with the original voltage control pot. As indicated by others, the added capacitance of the 8’ extension lead could’ve been the culprit. For safety, it’ll be a simple task to add an acrylic extension to the control. Mark ...

... post results once I get around to testing it. What I do agree on is the voltage regulation issue. Voltage output under load and no-load conditions ... can withstand the full potential of this type of supply PLUS a healthy safety margin. Although they are comparatively tough, I'm skeptical if they ...

... and 5mA on the main grid. Unsurprisingly the potential rises with grid voltage. It's nothing particularly interesting, but perhaps it will serve ... to 20kV and then 30kV as I got the hang of it. As mentioned before the safety features of the Spellman supply can be tricky to handle, and the plasma ...

... with a shunt resistor in series) is to protect the thyratron from large voltage reversals. Should a major spike occur, the diode is actually designed ... HV supply through a high wattage, low ohm (maybe 1 ohm) resistor for safety. This probably needs to be only 20kV, 1A rated in your case. Finally ...
