GS10C
Dekatron counting tube
Bi-directional double-pulse decimal counting tube.
Neon
filled.
The following pictures show the tube spinning.
Of course, only one of the cathodes is glowing, but the opening time of the
camera leads to that different pictures:
a middle opening time of the camera:
a short opening time of the camera:
a long opening time of the camera:
by night, with long opening time of the camera:
