CK6910 (Raytheon)
Dekatron counting tube
Bi-directional double-pulse decimal counting tube.
Argon
filled.
The following pictures show the tube spinning.
Of course, only one of the cathodes is glowing, but the opening time of the
camera generates different pictures:
a long opening time of the camera:
a short opening time of the camera:
by night, with long opening time of the camera:
An animation of a spinning dekatron (neon filled, colour not
like the GS10D!):
