New Measurements&On-Line Simulations are necessary
Study of the beam trajectory for:
- Laser beam mismatch at the cathode (Xlaser,Ylaser)
- Solenoids imperfections:
- misalignments (X center,Ycenter,)
- yaw ax, pitch ay
- RF-field symmetry distortion because of the coupling
- *BPM offset (Xoffset,Yoffset)
- ....
- The solenoids currents were varied in rather small ranges of values
- One solenoid current changing, while another solenoid is at the set point
- The rf-parameters scans were done with both solenoids at the set point
- Repeat previous measurements
- One solenoid current changing, while another solenoid is off
- On-Line RF-Gun simulation with solenoid off
