A question about some crt's ( round bw picture tubes)

[ChuckA]

In case anyone is interested in trivial CRT phosphor info:

P1 - Yellowish-green fluorescence, medium persistance, general oscillograph applications.

P2 - Yellowish-green flurorescence & phosphorescence, medium persistance, long phosphorescence

P4 - White fluorescence, medium-short persistance, B&W television application

P5 - Blue fluorescence, medium-short persistance, photographic applications

P7 - Very long persistance two layer screen, purplish-blue fluorescence, yellowish-green phosphorescence, low-speed application.

P11 - Brilliant blue fluorescence, medium-short persistance, photographic applications

P12 - Yellowish-orange fluorescence & phosphorescence, long persistance, low & medium speed applications

P14 - Long persistance two layer screen, purplish-blue fluorescence, yellowish-orange phosphorescence, low & medium speed applications

P15 - Visible green & invisible near-ultraviolet, short persistance UV, medium persistance green, used in flying-spot scanner CRT

P16 - Violet & near-ultraviolet fluorescence and phosphorescence, very short persistance, flying-spot video signal generator applications

P20 - Medium-short persistance, yellow-green fluorescence, high efficiency

P22 - Medium persistance, three color phosphor, color TV application

P24 - Short persistance, green fluorescence and phosphorescence, used for generating color signals from color transparencies.
