Titles differ between systems:

IPC: Tubes with amplification of output effected by electron-multiplier arrangements within the vacuum space

CPC: Tubes with amplification of output effected by electron multiplier arrangements within the vacuum space

Full Title

Full titles differ between systems:

IPC:

Cathode-ray tubes; Electron-beam tubes > having a screen on or from which an image or pattern is formed, picked-up, converted, or stored > Image pick-up tubes having an input of visible light and electric output > Tubes with amplification of output effected by electron-multiplier arrangements within the vacuum space

CPC:

Cathode ray tubes; Electron beam tubes (H01J25/00, H01J33/00, H01J35/00, H01J37/00 take precedence; details of cathode ray tubes or of electron beam tubes H01J29/00) > having a screen on or from which an image or pattern is formed, picked up, converted, or stored > Image pick-up tubes having an input of visible light and electric output (tubes without defined electron beams and having a light ray scanning photo-emissive screen H01J40/20) > Tubes with amplification of output effected by electron multiplier arrangements within the vacuum space
