How emission of electrons in vacuum tubes?
A heated metal in a vacuum with an electrical charge can emit electrons. The filament is the part of the tube that gets hot. Some tubes use electrons emitted from the filament. Others use the filament to heat a metal cathode, causing it to emit electrons. The electrons flow to a positively charged "plate" electrode through the vacuum.

Why do CRTs have a vacuum?
Cathode rays consist of electrons. In order to keep the electrons in a cathode ray from scattering due to collisions with air molecules, a CRT needs to be sufficiently evacuated of air.
Why CRT is to be highly evacuated?
The CRT (Cathode Ray Tube) depends on a stream of electrons. In order that the stream be able to do what it is designed to do, there must not be atoms in its way, otherwise, the stream would interact with those atoms. Thus, the CRT must be highly evacuated.
