What is this and what is it used for

Now you have me asking wht we don't call it Jigahertz...

Since I do not know what it is I should offer more info.

When originally found it was in an aluminum tube about 1/4 inch thick. The dumpster I found it in was behind the physics labs at the Univ. of Pittsburgh.

It looks like a gigantic triode, kinda, but I can't find one that looks like that.

I would guess it has something to do with radio transmission.

There are too many pins on the bottom for a triode but I can not rule out a pentode.

Inside the gold mesh there MAY be dynodes.

I should also add that whenfound it was thickly wrapped in balck electrical tape that I cleaned off to see what was inside. Between the aluminum tube it was in, and the electrical tape, perhaps they wanted to keep light out of it.

Maybe I should offer something else that I know what it is ? Why not!?

These are three genreations of the same thing. We all use them and if you ever see them it is really bad.

Magnetic media read heads?

Methinks that could be a photomultiplier vacuum tube.

Remarkably, That is a Phantastron from the AFC section of a SPS-10 Radar.  <Sea-Story> While busy actually troubleshooting that dratted section a very Jr. Ensign asked how I was progressing.  I replied, "I have it isolated to either  the phantastron or the reflex klystron"  The ensign wrote me up for being flippant!  The XO dropped the charges when I pointed out that those components actually did exist.

I am going to call both of the previous corect as far as I can tell.

I will stop there for today to let others play.

Take care,

Ben

We sent a rookie off to supply to get a fallopian tube in one my sea stories.

Ben, do you know which device that large R/W head came from? My first guess would be one of the drum drives from the 70's.

A CDC 9762 see here page 4 about 1974.
