Generation of magneto-immersed electron beams

Area of Science:

• Accelerator Physics
• Beam Optics

Background:

• Electron beams are vital for accelerator facilities, serving roles in electron coolers, electron lenses, and electron beam ion sources (EBIS).
• Magnetic compression is often required to reduce electron beam radius for matching ion beams or enhancing ionization for highly charged ions.
• Beam compression increases transverse energy, leading to larger electron trajectory angles, which can be detrimental.

Purpose of the Study:

• To investigate electron gun configurations for generating laminar electron beams.
• To understand the impact of electron gun design on beam quality for magnetic compression applications.
• To optimize electron gun performance for accelerator facility requirements.

Main Methods:

• Analysis of electron guns with varying configurations.
• Focus on achieving laminar electron beam properties.
• Consideration of magnetic mirror effects.

Main Results:

• Identification of key electron gun design parameters influencing beam laminarity.
• Demonstration of how specific configurations promote or hinder laminar beam generation.
• Quantification of the trade-offs between beam compression and trajectory angles.

Conclusions:

• Producing a laminar electron beam from the electron gun is highly desirable for efficient magnetic compression.
• Electron gun design significantly impacts the ability to generate laminar beams, essential for applications like EBIS and electron lenses.
• Further analysis of electron gun configurations can lead to improved performance in accelerator facilities.
