1. PARMELA computation for revised gun geometry C.Limborg-Deprey
Comparison 4 maps :
2D (omega2P) => no ports
3D (omega3P) => coupling port but original cylindrical cell shape
3D (omega3P) => with racetrack shape in full cell
3D (omega3P) => 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

4. Coefficient on Solenoid
Efield
Retuning the beamline for the “full” map
(= map including racetrack plus laser ports)
Varying Egun field
Varying Solenoid field
Varying RF
Coefficient on Solenoid

5. Maybe room for improvement
New tuning
x,80% = mm.mrad
y,80% = mm.mrad
Maybe room for improvement
With RF
