Re: Silicone tubing with hose barbs OK to pull low vacuum?

... you must be able to run negative polarity with high current (5-50 mA) and high voltage (25-100 kV) at the same time. Please keep in mind that safety precautions for these very high voltages are much more stringent than those for lower voltages to the tune of 5 to 15 kV. Voltage measurement ...

Re: tabletop neutron generator

... (in air) reached 50 kV. A good sign. So, I will next build a new oil tank and see what this monster will give me. With a massive resistor (for safety) I will use this new VM for my accelerator; that is, if it can really achieve the +100 kV or higher (maybe.) In any case, I am now moving on ...

... to dissolve the oil. Also, keep in mind that a fair amount of these solvents (xylene, toluene, benzene, etc.) are very toxic. Make sure to take safety precautions before working with them. It's the aromatic hydrocarbons that are most toxic. For volatile aliphatic hydrocarbons (e.g. hexane), ...

Re: Cleaning forepump oil out of a turbo

Hexane may work to dissolve the oil. Also, keep in mind that a fair amount of these solvents (xylene, toluene, benzene, etc.) are very toxic. Make sure to take safety precautions before working with them.

Re: Buying an He3 detector from an official supplier

I might have missed this in your post but have you directly discussed this with the safety person, yet? They may ask you for guidance on some aspects (like possible x-ray danger, as well) but they should be able to decide exactly what is required rather than us speculating ...

Re: Buying an He3 detector from an official supplier

Perhaps that would be for the best. If the detector shows that there is little to no neutron radiation, the safety team should have few reasons to disallow my reactor. I can continue using bubble dosimeters for my experiments while running the Ludlum in order to satisfy the safety ...

Re: Buying an He3 detector from an official supplier

The professor aiding me, Dr. George S. Brown, used to chair the Radiation Safety Committee. He stated that he understands my project is not particularly dangerous with respect to radiation. However, if a visitor were to wander by the physics department and contract ...

Buying an He3 detector from an official supplier

The Radiation Safety Committee has strict rules regarding neutron-generating devices, and I need to verify that my device is safe to operate when the correct procedures ...

... another for the metal stand (I feel any metal stand for a fusor should have its own ground - not necessary, of course but I feel that is a good safety practice.) Of course, the standard star system with the fusor is always the best approach. A minor point - consider using washers on your nuts ...
