Presentation Transcript

  1. KaoS Flow Analysis

  2. Experimental Setup

  3. Phase Space Distribution • Phase space distribution of protons from a FREESCO calculation for Ni+Ni at 1.93 AGeV • Dashed: Large Angle Hodoscope • Full: Small Angle Hodoscope

  4. Reaction Plane • Use transvers momentum method • reaction plane defined by sum of all measured transvers momenta • Projectile Spectators have equal longitudinal velocity

  5. Energy Loss • Spectra after time of flight and energy loss calibration

  6. Event Plane Determination • Small Angle Hodoscope not symmetric • Grey detectors not working • Assumption for all corrections is that reaction plane distribution is flat for minimum bias events

  7. Event Plane Determination

  8. Event Plane Determination Use only part between circles

  9. Event Plane Determination Correct count rate in rings of ΔΘ as function of ΔΦ

  10. Event Plane Determination
