Cyclotron Upper Bearing Maintenance Fall Protection System
Cyclotron Beam Developments
• Achieved beam intensity stability ±1% in BL2A and ± 2% in BL1A by suppressing νr = 3/2 resonance, and introducing active regulation

3/2 Resonance Correction in the CyclotronProblem: Radial variation of the current density was strongly modulated due to 3/2 resonance crossing.
Resonance correction: Simulation
Problem
Resonance correction: Measurements
Solution: A linear combination of two HCs, displaced azimuthally, provided full correction.
