Ion dynamics in the electron gun test stand
Beam Dynamics Aqui puedes decir que el precipitador esta alli porque querian evitar los iones que venian del dump donde los electrones colisonan se vallan a la fuente Beam dynamics has been made by Ricardo Soto and carlos hernandez The magnetic fields were imported from Poisson and Comsol
Secondaries dynamic: Solenoid effect Solenoid off Solenoid 200 A Solenoid 400 A
Anode bias effect Ion trapping and cathode bombardment by trapped ions in dc photoguns E. Pozdeyev there is some calculations about the ion flux in the article In the pictures the Secondary ions are generated outside the GUN to made clear the bias effect Bias 0 Bias 480
Bias 0 Solenoid on Solenoid off
Bias 1000 Volt Bias 1000 V solenoid on solenoid off
Bias -271 Solenoid On
Bias 1000 Bias -271
