Explore the impact of linear dispersion on beam emittance for beam positioning and control in particle accelerators. Investigate correlation between linear dispersion, BPM index, and steering effects on emittance quality to optimize beam performance.

If ONE of the YCOR/BPM (20th) is not present to launch the beam on to the curved linac – Linear dispersion corrected emittance (m) – vs. – BPM index Y-orbit (m)– vs. – s No steering Y-dispersion (m)– vs. – s Yp-dispersion– vs. – s
Linear dispersion corrected emittance (m) – vs. – BPM index 1:1 steering DMS
70th YCOR/BPM is not present Linear dispersion corrected emittance (m) – vs. – BPM index Y-orbit (m)– vs. – s No steering Linear dispersion corrected emittance (m) – vs. – BPM index DMS 1:1
STRAIGHT ILC BCD like LINAC emittance (nm) – vs. – BPM index 20th YCOR/BPM is not present DMS 1:1 70th YCOR/BPM is not present DMS 1:1
