This exhibit is a mystery and we would love to find out more about it and what it was designed to do. It has a nine contact base with long leads attached. The structure suggests an electron multiplier.![](../pics/abo0017a.jpg)
The Pinch with eight red-plat leads passing through it.![](../pics/abo0017b.jpg)
The electrodes are held in a glass rod - seen at the bottom of this image. The first electrode is L shaped. Subsequent electrodes are stepped. And this suggests a cathode at the base working to the next anode above.![](../pics/abo0017c.jpg)
The glass rod support and the dual supports for each plate arrangement.![](../pics/abo0017d.jpg)
The top of the envelope with evacuation pip and connection to the final plate. There is also a small glass rod support that appears to connect to the lower rod support.![](../pics/abo0017e.jpg)
A closer look at the plates.![](../pics/abo0017f.jpg)
The base with attached leads.The wide glass tube envelope is 37 mm in diameter, and including the base is 170 mm tall.Reference: Observation. |
