Variables Used
DC Transient Time - (Measured in Second) - DC Transient Time DC Transit Time refers to the time taken by an electron to travel from the cathode to the anode of an electron device and then back to the cathode.
Drift Space Length - (Measured in Meter) - Drift Space Length refers to the distance between two consecutive bunches of charged particles in a particle accelerator or a beam transport system.
Electron Uniform Velocity - (Measured in Meter per Second) - The Electron Uniform Velocity is the speed at which electron moves into a cavity while in a vacuum space.
Repeller Voltage - (Measured in Volt) - Repeller Voltage refers to the voltage applied to a repeller electrode in a vacuum tube. The repeller voltage is typically negative with respect to the cathode voltage.
Beam Voltage - (Measured in Volt) - Beam Voltage is the voltage applied to an electron beam in a vacuum tube or other electronic device to accelerate the electrons and control their speed and energy.
