USB Geiger Counter
Got the sparkfun USB geiger counter working today. The replacement PCB is a newer iteration. It bleeds the high voltage automatically. Nice upgrade. You can read the data from the virtual com port with...

Last night I controlled the fusor from LabView. I put together a simplified version of Andrew Seltzman’s Marc III controller. So far I can: graph the chamber pressure in realtime enable/disable fuel...

Spent some time in the lab. Really loving my new photo blogging capabilities. Shoot first, answer questions later. Friday’s photo stream. Saturday’s photo stream. Received a bunch of parts from mouser....
View ArticleDeepest Potential Well Yet: 43 Volts
All photos. I’ve been running shots on the Polywell yesterday and today. Just got my deepest potential well yet: 43 Volts. 10KV, 10mA on electron gun. 420V through coils. 8.5 millitorr air: Be sure to...

I asked Joe Khachan this question: Did you go to great lengths to reduce the resistance of the coil path? He responded: Yes we try and use a thick enough wire so that the resistance is small but it...
View ArticleNew High Voltage Probe
Just got this Tektronix P6015 high voltage probe. It goes up to 40 kV! Well actually it only goes to 27 kV without the fluorocarbon 114 dielectric. It’s huge! Shown next to a normal probe: Just in time...

All Photos Today, we tested the electron gun in tandem with the Polywell core. Right now, our goal is to simply understand effect the e-gun has on the potential well, if it has any effect at all. We...

All photos(1/2) All Photos(2/2) We weren’t satisfied with the layout of the inside of the chamber last time. The alignment between the center of the polywell core, the electron gun and the lagmuir...

All photos This project is moving into a new phase. Now that we have a working electron gun/polywell setup, it’s time to begin studying the way they interact. To do this, we need a more comprehensive...

It’s clear from the inconclusive results of the symmetry test that our experimental apparatus isn’t durable enough. It needs to for a long period of time over the course of many trials, without...
