Re: Neutron Club Application - Sarvesh Sadana

Sure, no problem. I'll try to do another run soon when I replace my drierite tube. Yup. The 300 CPM is the average noise floor generated by running the fusor at fusion conditions without any deuterium. I'm hoping that the ferrite will help absorb and limit the RF produced. The peak seen on the graph...

Re: Neutron Club Application - Sarvesh Sadana

I've been quite busy with schoolwork and haven't had much time to work on this. I have, however, installed the ferrite choke on the HV input line. What else can I do to reduce the noise?

Also, I'd appreciate it if Richard reviewed this.

Re: Neutron Club Application - Sarvesh Sadana

Very interesting. I definitely will look for a metal tube of the type you are describing -- that would be far easier than attempting to make a proper RF cage. After speaking to some of the folks at HEAS, I believe the problem lies in the power supply cable. The RF may be traveling along that wire, a...

Re: Cleaning forepump oil out of a turbo

Hexane may work to dissolve the oil. Also, keep in mind that a fair amount of these solvents (xylene, toluene, benzene, etc.) are very toxic. Make sure to take safety precautions before working with them.

Re: Neutron Club Application - Sarvesh Sadana

Yes, there are definitely a few problems with it. The issue with the faraday cage is the largest by far. Currently, the paraffin wax is actually screwed into the lead body, so I can't remove it without significant damage. I agree that the aluminum foil I used to cover the entrance of the cage is les...

Neutron Club Application - Sarvesh Sadana

Hi! I’m Sarvesh. I’m a senior (17) in high school. I’ve been working on building a fusor for about a year and a half. I apologize for not keeping a post detailing my fusion efforts in this forum. I have been too lazy to do so. I do, however, have pictures of my previous iterations if needed. A fair ...

Re: TMP Diagnosis

If you click on the pictures they will be oriented the correct way. It appears to be an issue with the forum software itself rather than the pictures (though I have noticed that some picture types work better than others -- PNG tends to work better than JPEG).

Re: Bonding Tungsten and/or Iridium?

It depends on the thickness of the tungsten. For thinner pieces (<.75 mm), continuous high current welding is fine. A simple hobby welder would do fine. Argon may be necessary, as it tends to oxidize. For thicker pieces, capacitive discharge welding is a must. In my experience, between 100-200 joule...

Re: [Theory] Electron-Degenerate Matter: High Power Density

It's worth mentioning that a physicist at a national laboratory told me that breakeven ICF fusion had been achieved by the military. Supposedly, it was classified so the public never heard about it.

Re: First Plasma (April 19, 2017) - Most Recent Plasma

Without more information, I would attribute the color change in the plasma to a combination of the grid melting (see: http://www.fusor.net/board/viewtopic.php?f=18&t=11341) and the pressure increasing. What is your grid made of? The pressure is far too high here. Based on the plasma, I would estimat...
