Sector Test Beam 2 - Dispersion, Matching

Sector Test Beam 2 - Dispersion, Matching. Dispersion Measured with frequency trims on the LHC frequency → SPS frequency at flat top coupled Maximum possible frequency trims +/- 2.4 kHz: dp/p +/- 3 permille Weekend 8/9 of August only +/- 800 Hz possible. ...re-phasing worked.

Presentation Transcript

  1. Sector Test Beam 2 - Dispersion, Matching • Dispersion • Measured with frequency trims on the LHC frequency → SPS frequency at flat top coupled • Maximum possible frequency trims +/- 2.4 kHz: dp/p +/- 3 permille • Weekend 8/9 of August only +/- 800 Hz possible ...re-phasing worked...

  2. Dispersion 23 (1) • Changes of polarity of the odd QTLs solved point 3 issue, measured also IR3 (TCSG.5L3.B1 was out) • Less good in the arc now... Results from weekend 8/9 of August

  3. Dispersion 23 (2) Results from weekend 23/24 of August

  4. Matching with Screens (Sector 87) • Not fully analysed yet • Can load optics with file... • (including tilt in LHC)
