Unformatted text preview: unwanted component along the ﬁeld B created by the coils (here we will disregard the Earth ﬁeld). The misalignment angle φ of the gun and the absolute value of the electron velocity v determine the components v || and v ⊥ . Find at which misalignment φ * the electron beams does not hit the glass rod in the tube any more. The rod radius is r = 2 mm. When the gun is oriented perfectly vertically the electron orbit radius is R = 5 cm 1...
