Critical race theory (CRT) is an academic field focused on the relationships between social conceptions of race and ethnicity, social and political laws, and mass media. CRT also considers racism to be systemic in various laws and rules, not based only on individuals' prejudices.
If the CRT is a black and white (B&W or monochrome) CRT, there is a single electron gun in the neck and the funnel is coated on the inside with aluminum that has been applied by evaporation; the aluminum is evaporated in a vacuum and allowed to condense on the inside of the CRT. [175]
The Democrat from Oregon also said that CRT is a legal framework not taught in schools and that Congress should focus on creating equity of opportunity for students in poorer districts.
Cathode ray tube, showing the yoke (copper coils and white plastic former) around the rear neck of the tube. A deflection yoke is a kind of magnetic lens, used in cathode ray tubes to scan the electron beam both vertically and horizontally over the whole screen.

Any vacuum tube which operates using a focused beam of electrons, originally called cathode rays, is known as a cathode-ray tube (CRT). These are usually seen as display devices as used in older (i.e., non-flat panel) television receivers and computer displays. The camera pickup tubes described in this article are also CRTs, but they display no ...
In a CRT, the vertical scan rate is the number of times per second that the electron beam returns to the upper left corner of the screen to begin drawing a new frame. [3] It is controlled by the vertical blanking signal generated by the video controller , and is partially limited by the monitor's maximum horizontal scan rate .
