Mark,
Great to see these caps finally getting some use. Nice work.

I grew up on a farm in northern Illinois during the 1940’s and 1950’s. By the time I was six I already had an intense interest (obsession) with electrical and mechanical things. Fortunately, my parents were supportive of this obsession, the result being a somewhat steady supply of mostly worn out ap...

One day it’s a fusor, the next a pumping station. On the pumps (Leybold D16A backing and Pfeiffer TPH-190 turbo) is my Ortec hpGe detector getting its annual bump and bake. Wrapped up in foil is an aluminum rod in contact with the detector’s cooling rod. Heat tape wrapped around the upper portion of...

Jim,

As to outgassing, was your titanium cathode pure Ti or an alloy? (The one I made was an alloy, 6Al-4V)

Only a 30-foot range? Guess I’ll need to buy two or three for the house plus another for my lab!

From my understanding the main purpose of the magnets was to help stability, I don't recall Joe saying anything (good or bad) about their effect on NPR. (Neutron Production Rate) My main interest is activation so maximum neutron flux at the sample is what I'm after. Stability was not an issue for me...

Frank, great idea that may help us get to the bottom of this conundrum, much appreciated. I’ve worked on this just enough to realize that the detector clamped in a lab stand is not going to cut it, takes too long to reposition the detector and is not very accurate. I’m in the process of upgrading my...

304 SS cathode images. Removed after about two weeks of runtime, the majority of that time at 400 W input power. (40 kV, 10 mA, 2.4E+06 n/s) There are two things I find interesting, the narrow ring around the cathode's internal circumference and the whiskers it grew. My guess is the ring is where t...
