WESTERN ELECTRIC 6l67 ELECTRON TUBE

DESCRIPTION

The 6167 is a ten-stage cold-cathode gas-discharge stepping tube designed for
continuous counting or registration of pulses at rates up to 1000 pulses per
second. Each stage consists of a stepping cathode (En) followed by an output
cathode (Kn). Connections to each output cathode permit obtaining an output
signal from each or any stage. A normal (zero) cathode is provided outside the
counting ring and operates into the first stepping cathode (Bl). The auxiliary
anode can be operated to supply an additional output signal when current is
carried from K10 cathode. The direction of forward transfer of discharge is

in a clockwise direction and the position of the cathode slow may be observed
through the top of the envelope.

All data are based on operation of the tube within average current
ratings at the time of stepping or transfer of the discharge. -

Voltage, with respect to an operating cathode, at which conduction
occurs from the auxiliary anode to cathode indicated.

Measured with maximum K10 voltage of +50 volts with respect to the
operating cathode.

Voltage, with reapect to an operating cathode, applied to the adjacent
forward cathode to transfer the discharge to that cathode.

Measured under static conditions. This is an absolute limit on output
voltage but as frequency of operation is increased, the available output
voltage is decreased because of residual ionization in the preceding
cathodes.
