T5470
The Tektronix T5470 (P/N 154-0429-00, 154-0450-00, 154-0451-00, 154-0452-00, 154-0457-00, 154-0458-00, 154-0459-00, 154-0478-00, 154-0478-01, 154-0478-02, 154-0478-03, 154-0568-00, 154-0568-01, 154-0568-02, 154-0568-03) is a 5" electrostatic deflection CRT used in the 543B, 544, 545B, 546, and 547.
It was designed by Connie Wilson.
It has an aluminized round flat face with 6 cm of usable vertical scan, and a helical post-accelerator. The entire envelope of 154-0478-xx is made of glass. The newer T5471 (154-0568-xx) has a ceramic envelope.
The T5470 has a specified dot size of 0.004", quite a bit tighter than the dot on higher-bandwidth CRTs that use an expansion mesh.
The 519 has a very different CRT, but the same specified dot size as the 154-0478-00.
