Re: Hello from Virginia

... mentor; that is, do far too much. Learning is a skill one can best achieve by trying and (sometimes) failing. Realize that your primary job is safety (so you must understand the issues very well), but mostly providing direction not doing it for them. Learn to step in only if you feel they have ...

Re: Problem with Canberra Series 30

Ok, I solved the problem, I'm just stupid. To give the supply voltage in the safety, at the instrument under test, I use a 230/230 isolation transformer and a variac with which the straight edge voltage, starting from a hundred volts, and if there are no problems ...

Re: Plasmagun/railgun for Stelarate

... (and the trace oxygen levels are far lower still.) DO NOT ever expose H2/D2 at or anywhere near atm pressure with arcs! Have fun but do remember safety is paramount.

Re: First Colorado Design Sequence

... neutron radiation in any case and an Am source is just Alpha's - and as I mentioned, a Be/Am system will produce too few neutrons to be much of a safety hazard.

Re: Plasmagun/railgun for Stelarate

... accelerator (its voltage multiplier.) I never touch any part of these systems without first checking them with the ground stick. Another important safety issue - caps that are rapidly discharged can over heat and explode. Shielding and proper safety eye wear is essential, too. Those exposed rails ...

Re: Plasmagun/railgun for Stelarate

... pulse should get to 20000K increase the meanfreepath and at the same time lower the resistance. @Rex Allers and Richard Hall Being working on the safety and capacity, the picture below is abit better, plan to solder the connections just need a 100watt iron, and electrical tape it up.

Re: Low Tech Gas Feed Solution

... this to be an understatement compared to the reality! Also, when the star ground configuration is used (and always a good idea to use this for safety!), one is also "piping in" huge voltage surges into the ground system which all your electronics can easily "see". My poor ...

Re: Plasmagun/railgun for Stelarate

A difficult project but very interesting approach. Do post as you can. Also, be very careful - cap banks are very dangerous at even moderate voltages. Consider bleed resistors and always assume they are charged - so, use a safety shorting stick to check that they are discharged before servicing.

Re: Daniel Klasing- Plasma Club Application

... to my fusor; a real fusor supply (which you may have no interest in) is terribly lethal and having redundant grounds is both smart and a critical safety feature - especial with a metal support structure. Using just a ground through the power supply isn't the safest way to go; a master ground wire ...
