KaoS Flow Analysis
Experimental Setup
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
Reaction Plane • Use transvers momentum method• reaction plane defined by sum
of all measured transvers momenta
• Projectile Spectators have equal longitudinal velocity
Energy Loss
• Spectra after time of flight and energy loss calibration
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
Event Plane Determination
Event Plane Determination
Use only part between circles
Event Plane Determination
Correct count rate in rings ofΔΘ as function of ΔΦ
Event Plane Determination
