Re: High Voltage Supply for PMT

Tons of CCFL transformers are now FREE!!! CCFL lighting of all sorts is going the way of the dodo bird. Actually, it effectively, died a few years back. Too many would-be electronics builders follow a rigid part numbered scenario rather than build the circuit and shove in a fairly common seeming equ...

Re: New pulsotron production line

Fabulous! Amazing! I can hardly wait to get one of these kits!
This will definitely change the world as we have come to know it.
Beyond this I can only say.......Wow!

Fake news has made its way to fusor.net

Re: Neutron temperature

If it is real and moves someone can clam it has an equivalent temperature. All of this ridiculous temperature bit has been dealt with in the FAQs here There are several related to this issue. Read the FAQs and learn! Oddly, the critical FAQ and subsequent discussions are in this very forum......... ...

Re: A Bunch of Failures

I feel that a general comment is due here. You have had more problems than one might imagine related to just arriving at even a very crude and worthless vacuum level. This is virtually unheard of in these forums. Can you trust your gauge? We do not know. Do you have a good pump, at last? We do not k...

Re: Serial communication

I would go to the Arduino home page and there is a very adroit crowd there in the troubleshooting forum, just itchin' to help if you define your problem well. I have never tried to send-receive out of the serial port on the arduino I tend to go for I2C communication (two wire interface). I do use th...

Re: Hello from Richmond, VA!

Welcome James, I am glad to hear that you are starting to be able to have a workshop/lab of sorts. Working with the hands to make experiment is a good thing for any scientific minded person.

Re: Question About Design Trade-offs for Backing Pumps

The 5 CFM Yellow jacket that I had was 15 years old and was 100% U.S. made. In spite of it having been used in HVAC work for God knows how long, it still pulled to 10 microns in the bell jar of fusor II. I can't speak for current product. The gauge is worthless and is in inches of vacuum. Only a goo...

Re: Alternative Reactor Design

Thanks for recognizing that I was talking about absolute, 100% continuous neutron flux systems that are start'em up then walk away for months, years with a good stable flux. Only one exists....Fission reactors. Waste heat makes electricity. Fission reactor neutrons can make more fission and fusion f...

Re: Question About Design Trade-offs for Backing Pumps

if you can reach 35 microns, fine. However the rule is go as low as you can go on the foreline pump. A diff pump goes lower if you can go below 10 microns on the foreline at the inlet. As we have in the FAQs Find out what your pump can do with a known good TC gauge at the inlet. That is what the dif...

Re: A Bunch of Failures

It will pump or it will not pump regardless of oil. This is not a new pump. Remember it was bought from a guy who shipped it with oil in it. Not a real vacuum head who owned it last. No good vacuum head ships a pump full of oil.
