Multi-bend cathode ray tube

Cathode ray tube apparatus comprising:

• an electron gun;
• a biaxially controllable deflector downstream of said electron gun;
• a display screen downstream of said controllable deflector;
• and
• a magnetic loop bender disposed downstream of said electron gun but upstream of said controllable deflector, said bender having a bender magnet structure which includes north and south poles disposed on opposite sides of a bending plane defined by central axes of said electron gun and said controllable deflector, both said north and south poles terminating in a pole termination plane which is perpendicular to said bending plane,
• wherein said bender magnet structure is sufficient to bend an electron beam from said electron gun through a bending angle that is between 225° and 315°, inclusive.

A method for controlling an electron beam in a cathode ray tube, comprising the steps of:

• providing said electron beam from an electron beam source position;
• magnetically bending said electron beam through a bending angle that is between 180° and 360°, exclusive;
• and
• biaxially and controllably deflecting said electron beam toward desired positions on a display screen after said step of bending.
