Instead of the previously used single post-deflection acceleration electrode, high-performance CRTs in the 1940s/1950 began using a series of separate accelerator electrode bands applied to a cylindrical bulb. These bands were separated by insulating bands, and supplied with progressively higher voltages through individual HV connectors.

A disadvantage of this scheme is the additional distortion and compression it causes.

The 5XP CRT is an example of a tube using multi-band acceleration.

Multi-band accelerators were replaced by spiral accelerators in the course of the 1950s.
