Power Supply using Car Amp, Transformer and 5X VM

[ INTRODUCTION I have replaced my Fusor's power supply. My goal was to use components that are easy to obtain, and at a reasonable cost. This new power supply did work in my Fusor, and produced 3000 CPM, as compared to 300 CPM from my previous power supply. SAFETY Extreme care is needed when working...

Re: Steven Haid's Fusor

I have a few ideas on what I might do next. 1) The setup has some mechanical issues with the table. Also the table being against the wall makes it difficult to access the rear of the chamber. I plan to fix these problems. 2) Before I found the dental X-Ray transformer I was studying how to make a po...

Re: Steven Haid's Fusor

Dennis, I just ran the test you suggested, running the fusor at power for 3 intervals. The first and third interval did not have a moderator, and the second interval did have the moderator. The base count rate without the moderator and with full power is about 24 CPM. Refer to the following screensh...

Steven Haid's Fusor

I am applying to the Neutron Club. I apologize for not posting the construction progression of my fusor. I have just read the requirements for claiming fusion, and see that I should have been doing that. Hopefully I can make up for that with this detailed report. I have made extensive use of this we...

Re: xray transformer questions

Thanks for clearing that up. I did some reading on how these x-ray machines work, I wish I had done that before. An X-ray machine has a main HV transformer, the output is converted to DC and applied to a cathode and anode target. The cathode needs to be heated so that it can release electrons, the f...

xray transformer questions

I am starting work on replacing the NST with an Xray transformer in my power supply. My xray transformer has 3 wires coming out of the secondary. I was expecting that one of the wires was a center tap, but when measuring the resistance I found that the wire labeled GND does not seem to be connected ...

Data acquisition software

While building a fusor I am developing software to capture data from the fusor and record, display, and graph the data. The goal is to display the image from the camera, HV voltage and current, chamber pressure, and neutron counts per minute. The software displays, graphs and records the data. The s...

Re: Adjusting Ludlum 2000 for Neutrons

Thanks for the advice on getting the C-BNC cable from Ludlum. It arrived yesterday and I connected my Ludlum 2929 to the HE3 tube and it gets counts. The Ludlum 2929 is a dual channel scaler that is generally used with an Alpha/Beta sample counter. The manual says it also works with Proportional det...

Re: Adjusting Ludlum 2000 for Neutrons

I purchased the same HE3 tube which has a BNC connector. The BNC connector has a maximum voltage rating of 500 volts. But the tube needs 1750 volts. The Ludlum 2000 has a Series C connector.

Did your tube have a BNC connector. Could you explain how you connected it to the Ludlum 2000?
