Beam emittance reduction during operation of Indus-2

Area of Science:

• Particle accelerators
• Synchrotron radiation technology
• Electron beam physics

Background:

• Indus-2 is a 2.5 GeV third-generation synchrotron radiation source.
• Initial commissioning utilized moderate optics.
• Challenges in storing beams at 550 MeV necessitated an alternative injection strategy.

Purpose of the Study:

• To detail the beam injection procedure for the Indus-2 storage ring.
• To discuss beam dynamical studies relevant to injection and storage.
• To describe the transition from moderate to low emittance optics and emittance reduction techniques.

Main Methods:

• Utilized an off-momentum electron beam for injection to circumvent storage difficulties at 550 MeV.
• Implemented a switchover to low emittance optics at 2.5 GeV post-beam storage.
• Developed and applied procedures for reducing beam emittance during operational phases.

Main Results:

• Successfully commissioned the Indus-2 storage ring with a robust injection protocol.
• Demonstrated effective transition to low emittance optics.
• Achieved reduction in beam emittance through implemented operational procedures.

Conclusions:

• The developed injection and optics transition procedures are effective for Indus-2 operation.
• The implemented methods facilitate enhanced performance through beam emittance reduction.
• These strategies contribute to the efficient utilization of the synchrotron radiation source.
