Given:
Relative permittivity of water εr = 81,
Applied voltage V = 4 MV.
Task:
Calculate the electric field distribution in the device. Find the charge on electrodes.
Solution:
Electrostatic field and charges distribution in the Prepulse Switch used in the improved Gamble generator design.
Results:
Electric field distribution in the water around the groups of electrodes:
