The EN10 strobe tube is a cold cathode triggered discharge divice thet Ferranti call a 'Neostron'. The operation of a triggered discharge is identical to the operation of a thyratron and that is the other function of the EN10. Ferranti also made the NSP1 'Strobotron' neon discharge tube.
Strobeoscopes used flashing light of variable frequency to observe moving machinery. A gear wheel observed at the correct flash rate would appear to be stationary.
The anode connection has an insulated support and connection so as not to trigger the discharge.
The wide glass tube envelope is 28 mm in diameter, and excluding the IO base pins is 86 mm tall.
Reference: Datasheet. Type EN10 was first introduced in 1961.
