This rare counting tube is a 10 kHz polyatron or “inverse dekatron”. While traditional dekatrons have a central anode surrounded by a ring of cathodes, polyatrons have a central cathode surrounded by a ring of anodes and a screen electrode. This structure prevents cathode poisoning, but it also prevents direct viewing of the count through the top of the tube. Polyatrons can directly drive Nixie tubes.
