Engineers and scientists use MICHELLE to analyze and design a wide variety of electron and ion sources, accelerator beamline components, and vacuum electron device components. The code is used in industry, national laboratories, and academic research institutions.
MICHELLE can model devices that range from simple 2D axisymmetric devices to very complicated 3D devices, including those with fine geometric features on disparate spatial scales. The following are some examples of devices MICHELLE can model.
Electron sources: pierce diodes, axisymmetric diodes, annular beam diodes like magnetron injection guns (MIGs), multiple beam guns, sheet beam guns, and gridded guns.
Ion sources: volumetric ion sources, ion thrusters.
Beam transport and focusing systems:
Accelerator component beam transport using magnetic field focusing or electrostatic focusing, electron and ion beam lithography (single beam and multiple beams), beam control for large-scale electron beam materials processing.
Beam dumps, depressed collectors, multistage depressed collectors.
