Vacuum tube DY86 emits X-ray

DY86 in a regulated high-voltage power supply. Glows really nice, does it?
(note: the radiation is actually too weak to capture pictures)

Very nice!

Would you be so kind and tell me which pins are you used for anode and katode?

[TheReal1inflater]

@crnazvijezda Anode is the upper cap, cathode bottom pins 1,4,6 or 9, they're all interconnected so it doesn't depend on which will you use. It won't hurt if you'd just short them all with a wire for this setup.

why was it making blue light? was this just the electrons bombarding the spattered material on the tube walls? I hit this spare old lamp I had with 60kv and it made a greenish yellow glow reminded me of crooks tube I think this was the krypton gas or maybe phosphorescent material, I was trying to make a small plasma ball but I guess it was the wrong bulb type or maybe I was doing something wrong, have no idea how they make those light bulbs glow blue n purple like a miniature plasma ball?

@ARCSTREAMS Depends on the tube and the vacuum level. To say the least, these tubes are small and this particular piece was NOS, so at this forward-mode configuration it emits lesser amounts of radiation and also it glows like a neon lamp, except with a blue glow, might be corona on the walls.

I should have an another video of the DY86 tube here; be sure to check it, did a real measurement there, also did a reverse-polarity setup (sparks were crawling along the tube)

[ARCSTREAMS]

sound like your radioactive detector in the background was really clicking away

[TheReal1inflater]

@ARCSTREAMS Haha, that's nothing. Check my x-ray tube or 6VS-1 video, in there it chirps like an AM radio.

[ARCSTREAMS]

already saw it that was the first video i saw love the glow, but perhaps if there was less glow it would indicate that more xray was being produced maybe the real good ones dont glow as much ( wasted energy)

[ARCSTREAMS]

I was googling x ray tubes and its very interesting stuff they show similar rec tubes like you got, seems they work on materials such as cooper, tungsten,molybdenum, palladium and rhodium witch I think is radioactive, what bombardment material does your tube have? it say only about 1% of the energy is converted to x rays but still your tube can be hazardous and may even be able to take pics if ran at 60kv, just a matter of hitting the right wavelength.

I am too afraid to look at it

[sjoerdbeukers]

well every tube does that a little bit.
