Orbit Response Measurements

Update 9/30/10

J. Rzepiela

orbit response program
Orbit Response Program
  • Any corrector in any sector is selectable
  • The max range, number of kicks, and settle time are configurable
  • Orbit response at each BPM in sector is measured for each kick
  • Can display measured orbit response, model orbit response, etc.
measurements
Measurements
  • 3.464 GeV, 250 pC
    • LTU
  • 4.3 GeV , 250 pC
    • LI21, LI27-30, BSY, LTU, UND (partial)

LI21 Results (XCOR)

Larger signal in normal component (as compared to model) and

near zero signal in skew component implies a error in scaling (as opposed

to rotation

Small error in normal component (as compared to model),

large skew component

orbit response fitting
Orbit Response Fitting
  • Fit data from all x and y corrector kicks
  • Use all BPM data.
  • Fit gain and angle parameters for all BPMs.
    • Correct BPM signals to account for scaling in x and y (gx, gy) as well as rotation (φ).

general observations
General Observations
  • Xcorr scans show generally good agreement with model
  • Ycorr scans for Ycorr 453  767 show generally good agreement with model
  • Ycorr scans for Ycorr 105  393 show poor agreement with model, particularly farther downstream (BPMs 110  450 show better agreement than BPMs downstream)
