TUYAB01 Transverse-transverse and Transverse-longitudinal Phase Space Converters for Tailoring Beam Phase Spaces 775
 
  • K.-J. Kim
 
  This talk covers basic beam dynamics theory, including emittance converters and the flat beam technique, and also new ideas for transverse-longitudinal coupling. The work done in collaboration with SLAC, FNAL, and NIU, including a preliminary experiment performed at Fermilab, is to be presented.

TUYAB02 Generation and Control of High Precision Beams at Lepton Accelerators 780
 
  • Y.-C. Chao
 
  Parity violation experiments require precision manipulation of helicity-correlated beam coordinates on target at the nm/nrad-level. Achieving this unprecedented level of control requires a detailed understanding of the particle optics and careful tuning of the beam transport to keep anomalies from compromising the design adiabatic damping. Such efforts are often hindered by machine configuration and instrumentation limitations at the low energy end. A technique has been developed at CEBAF including high precision measurements, Mathematica-based analysis for obtaining corrective solutions, and control hardware/software developments for realizing such level of control at energies up to 5 GeV. Further, results on achieving rms energy stability at 10-5, rms relative energy spread below 3x10-5, and position control at micron level are presented. These results manifest the CW SRF electron linac stability capabilities and are valuable for a large range of applications, including ERLs and Electron-Ion Colliders for Nuclear and Particle Physics.
