Measurements with Centred Beam

Horizontal Corrector Scans

  • Tune file: ctf3cbpmAll_20130506_160441.dat
  • Processing file: ddc_130506_140441.json
  • Final triplet currents: 0, 44, 62.4 A
  • Energy: 207 MeV
  • Single corrector
  • 1.9 ns pulse, no attenuation
  • exclude 172128, 171547
  • ignoring the first corrector position, the χ2/d.o.f. for the scale fit becomes much smaller but the scale only changes slightly. This is due to scraping.
