Re: Scroungers club deleted

The rub in all of this is time. Every day is Saturday for you Richard. Through all of my later fusion work, it has been to test other configurations and conditions. It is interesting to me to do that. To run the standard fusor for multiple days just to get it conditioned to get the neutron numbers u...

Posting in the Appropriate Forums

Behind the scenes, more and more post are having to be relocated to the appropriate forums namely the New User Chat area. Let me restate the criteria. Technical forums are for CONTRIBUTIONS and non-trivial discussions. New User Chat area is for simple questions and interactions. Asking about a scrou...

Re: Grounding - neutral wire or grounding pin

The neutral wire is really back to the center tap of the transformer. While it is grounded, it is a long path pack to the pole and the transformer. This path offers resistance and inductance that can cause local voltage build up during a voltage spike. Grounds are best when they are closest to the s...

Re: Low current, high voltage safety

You would not want to grab both leads. While there is probably not enough power to stop your heart, you will get a very big surprise. It will bite and bite you hard because at 5KV, that current will flow through your body and it will not be pleasant.

Re: LUDLUM 48-1614 MODEL 15 NEUTRON COUNTER DOSE SURVEY METER

They are two separate independent units so as such they will not be calibrated together. The meter is stupid. It does nothing more that count pulses above a threshold voltage. The calibration for the meter then is just to put in a standard number of pulsed above that threshhold and be sure that is t...

Re: Delta rays

Thanks for the history lesson Richard. I knew some but not all of that. Still, people are so freaking confused by radiation when you add the neutron that it seems that some better lay system should be in place. I know the sub and minor particles and rays are endless but the main four or five should ...

Re: LUDLUM 48-1614 MODEL 15 NEUTRON COUNTER DOSE SURVEY METER

The meter part of your setup is much like the rest of the Ludlum lineup. Calibration is best achieved with a pulser. That lines out the counting. The rest of the setup is done with the tube. He3 tubes have a very low output compared to others. Normally they are set to 2 mV to read the pulse. There i...

Delta rays

Consistent with alpha, beta, and gamma rays, why were neutrons not called delta rays? I know 35+ year elapsed in the naming but I am curious why the nomenclature changed. It seems like the Delta ray would have been easier for people that are not in the field to learn when grouped with the others.

Re: HEAS 2020 Photo Archives post your images here!

It is not fun wearing a mask all day for work or for socialization. No argument there. Yes, I am busted in the video and in some photos. Time is short in our lives and it is indeed a balance between risks and rewards. I did in fact did not wear a mask when we were outside and people respected the ro...
