Comparison 4 maps 2D (omega2P) gt no ports 3D
(omega3P) gt coupling port but original
cylindrical cell shape 3D (omega3P) gt with
racetrack shape in full cell 3D (omega3P) gt
with laser ports in ½ cell and racetrack shape
2
No coupling ports
With coupling ports
Suppression of quadrupole head-tail with the
racetrack shape of the full cell

• Retuning the beamline for the full map
• ( map including racetrack plus laser ports)
• Varying Egun field
• Varying Solenoid field
• Varying ??RF

New tuning ?x,80 0.908 mm.mrad ?y,80
0.915 mm.mrad Maybe room for improvement With
??RF
