The Buccaneer Strike Sight (Head Up Display) was supplied in two pressurized containers; the Head Up Display Unit and the Waveform Generator. The Rank Cintel precision Cathode Ray Tube had a two inch screen and had a broadband green P1 phosphor (described as zinc orthosilicate or willemite). Electro-magnetic deflection and permanent magnet focusing were used.
The tube operated with a 20kV EHT, a beam current of 20-100microamps and gave sufficient luminance for the symbology to be visible against background illumination of 10,000ft Lamberts thereby achieving a contrast ratio of 1.2:1. The spot size was 0.007 inch and resolution was approximately 280 lines. The CRT was warranted for about 50 hours. The Mark I display had a valve EHT Unit which took ages to power up. Later versions had a solid state EHT. The CRT is also identified as CV6050, G0602-J2.
The CRT housing is an interesting assembly with a moulded plastic insulator for the tube body and EHT stem with an outer of machined Bakelite.
This is just the CRT without the Bakelite housing.
The cone of the CRT bulb is marked "TF49".
