Draw a picture of the CRT with an undeflected electron beam. Since you will not be using electric fields, you do not need to include the deflection plates. Draw a coordinate axis on this sketch and show a region occupied by a uniform magnetic field for part of the electron's trajectory. Determine the direction of this magnetic field to give maximum deflection. Draw the electron's path entering, through, and leaving this region of uniform magnetic field to show the beam deflection at the screen. Also show vectors representing the electron's velocity and acceleration in each part of the path. 2. What is the force on the electron if the magnetic field is along the electron's path? What is the force on the electron if the magnetic field is perpendicular to its path? What path does an electron follow while traveling through a constant magnetic field that is always perpendicular to its velocity? 3. Determine the velocity of the electrons as they leave the electron gun in the CRT as a function of the potential difference of the two accelerating plates. 4. Determine the position, direction, and velocity of an electron entering the region of constant magnetic field. Determine the position, direction, and velocity of an electron as it leaves the region of constant magnetic field. What type of curve is the electron's trajectory in that region? 5. Determine the path of the electron as it travels after it leaves the magnetic field region until it strikes the screen. Use geometry to determine how far from the center the electron strikes the screen. 6. Make a picture showing how would you position the CRT in the Helmholtz coils to give you a region of uniform magnetic field that is perpendicular to the velocity of the electrons in the electron beam?
