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 team. I plan on im...

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 a headache (knowing that my reacto...

Buying an He3 detector from an official supplier

I'm in the process of transferring my reactor to a lab space at my university to start a plasma physics research group. The professor helping me has tasked me with finding a neutron detector capable of high accuracy readings from an official manufacturer (not eBay). Costs will be covered by my unive...

Re: George Ressinger Fusion Club

The good thing is that you are operating your reactor within the fusion realm. If your numbers are correct, you should be doing fusion. However, I must change my verdict and agree with the others who posted here. Bubbles due to heat would explain the localized bubble formation as well as the surpris...

Re: George Ressinger Fusion Club

Amazing job! If my calculations are correct, your fusor was producing 500,000 neutrons per second (or 1,000,000 fusions per second). Congratulations from a fellow high school fusioneer! It is a little strange that there are few bubbles near the top of your dosimeter, but this is likely due to an une...

Re: Daniel Klasing- Plasma Club Application

You have a plasma in your device, but your pressure is nowhere near 10^-4.5 Torr. By looking at your plasma, I would guess your real pressure is above 1 Torr. This wouldn't be too concerning except for the fact that you said your diffusion pump was operating. Operating your diffusion pump above 0.3 ...

Re: Spellman DXM70N600X3547 power supplies on ebay -70kV 8.5

I have also not been able to verify that my router identifies the power supply via direct ethernet connection. The IP address does not work. I logged into my Xfinity account at 10.0.0.1 and looked at all connected devices. The power supply was not listed anywhere. My supply does not indicate any sig...

Can you verify the HV connector type? I know these units sometimes have specialized connectors and it is difficult to tell by the picture.

Ionizing radiation as a function of time

I recently finished editing the 5+ hours of raw video I had recorded constructing and operating the fusor into a 15-minute video . When I was editing, I decided to graph the Geiger counter data that was picked up by the camera. Here is the data: https://s12.postimg.org/5s5sxxs7x/Rate_of_change_of_io...

Re: Neutron Club Application- Zan Chaudhry

The anomalous pressure reading is due to inaccuracies in your equipment. Like you, I used a CPS VG200 vacuum gauge for my fusor. After pumping with only the mechanical pump, the gauge read 0 microns. My mech pump is rated at an ultimate pressure of 12 microns. When that gauge reads 0 microns, the re...
