Nixie sighting

[Grahame]

CERN Proton Synchrotron Control Room 1966

Several nixie displays (right colour and size but fuzzy). What's the display technology in the top right corner?

[Adrian Godwin]

It could be etched edge-lit acrylic, or perhaps a back-projection display. Fran Blanche on youtube has detailed several such devices, eg https://www.youtube.com/watch?v=0TD_MhPpZKg

Her pieces on the Nimo displays (shaped masks in a CRT) are particularly interesting.

+1 for edge lit, I dont think it's projection since the font appear thinner and the background isnt as dark

Top right looks like a status display for the accelerator
