The copper foil at the end of the deflection tunnel and the silver one at the end of the focusing electrodes were in fact ultra fine mesh (~200 micron). The principle behind them is to reduce reflected and secondary emissions from adding noise to the signal by using a 'shotgun' collminator. The fibre channel device has a reddish tinge to it,most likely some tellurium salt, suggesting it was most likely a near UV selective filter, considering polycrystalline silicon is most sensitive to UV light.

To some degree yeah, but most development it's simply parts get smaller or integrated but the principles remain. Items like this require a huge investment of processes to manufacture which would be impossible to repair or replace. CRTs are heading the same direction

I have found that the easiest, quickest, and safest way to release a vacuum from a tube like this is to grab the seal stem with a pair of pliers and crush it. Love the vids - keep up the good work.

I had one of these years ago and was able to free the intensifier from it by very carefully heating the front glass plate. It was bonded to the IIT subassembly fiber optic array with what appeared to be epoxy. The IIT unit lived in a home made X ray imager for a long time ❤

That's the sad thing about old technology like this, all those man hours and experiments and research to produce and now obsolete. It's easy enough to understand the basic principles of how they work but I would like to hear the designer explain the function of each component, the thin metallic films etc. (I've never had luck with the heat glass cutting method but I've seen it done with success, it's as much about cooling it down quickly to create stress).

So for the 3 thinkers here Be is thought dangerous in its metal form. On the other hand the Be metal would be used for applications that need soft X-rays to pass through.

you could have used yarn and soak it in a flammable liquid tie it on the tube and light the yarn on fire and twirl it around and the heat will concentrate and cut off the tube

i had to look it up in my book but i heard something about copper foils in xray microscope last year in a course on university: the foil is placed in front of the object you want to look at. The foil (or target foil) is there to be hit by a electron beam and will emit the xray on the other side. so maybe same principle here: You get electrons from the lense and convert them into a scanning x-ray beam.

Whenever you upload something, it's about stuff I've never seen before (and I'm quite inquisitive in tearing down things). The way I've seen glass broken by heat, is wrapping an alcohol soaked string around it, lighting it and then drench it with cold water.

To break glass with the hot wire method you need to score it first, to provide a weak point where you want the glass to separate. See 4:20 onwards in this video for a demonstration: watch?v=gl-QMuUQhVM

My God man! Why on Earth would you destroy such a rare vacuum tube when you can simply find very detailed drawings of them in literature? I have a book published by Magraw-Hill in the late 1980s that tells far more than one can learn by destroying the device itself. Why didn't you power up the tube and demonstrate how sensitive it is and how good its' images are? Any fool can wreck things. Maybe the joke's on me and you were wrecking the tube to try to appear ignorant on purpose. That came through.
