Suppressing the X-Y coupling effect in compact electron storage rings.

Area of Science:

• Accelerator Physics
• Particle Beam Dynamics

Background:

• Electron storage rings are crucial for various scientific applications.
• X-Y coupling and beam profile tilt degrade accelerator performance.
• Compact storage rings face space limitations for correction systems.

Purpose of the Study:

• To effectively eliminate the x-y coupling effect in the Super-ALIS compact electron storage ring.
• To address beam profile tilt caused by skew-quadrupole perturbations.
• To develop a simple and space-efficient solution for coupling suppression.

Main Methods:

• Utilized a single thin skew-quadrupole magnet.
• Targeted and suppressed harmful Fourier components of skew-quadrupole perturbation.
• Implemented the method within the Super-ALIS compact electron storage ring.

Main Results:

• Successfully eliminated the x-y coupling effect.
• Effectively suppressed beam profile tilt.
• Demonstrated the efficacy of the single-magnet approach.

Conclusions:

• A single thin skew-quadrupole magnet is a simple and effective solution for x-y coupling suppression.
• This method is particularly suitable for compact storage rings with limited space.
• The technique offers a practical approach to improving beam quality in accelerators.
