Web12 sep. 2024 · The time for the charged particle to go around the circular path is defined as the period, which is the same as the distance traveled (the circumference) divided by the speed. Based on this and Equation, we can derive the period of motion as. (11.4.3) T = 2 π r v = 2 π v m v q B = 2 π m q B. If the velocity is not perpendicular to the ... WebThe ion cloud represents a region of positive space charge. From Poisson’s equation in cylindrical geometry 1 r ∂ ∂r (rE r) = n ie ε 0 (3.15) we obtain E r = 1 2 n ierε −1 0, i.e., the electric field increases linearly from the center to the edge of the ion cloud. Hence, the E × B velocity increases in the same man-
