Changing the quad settings
facet home → Profile Monitor → LI20 → SPEC LINE GUI
- Leave big "Dipole" switch in "Without" setting (dipole energy is not adjusted)
- Set "Z Object" to the position where the beam should be imaged, e.g., the center of the PB
- Set "Z Image" to the position of the screen, e.g., z=2015.26 for DTOTR
- M12, M34: transfer-matrix elements (set both to 0 for re-imaging)
- Energy: determines where the focus is
- Press "Calculate and Trim"

Changing the dipole settings
- It is important that the e-beam never passes through the CsI array
- Move the screen for LVOF: Experiment → LI20 → MC01 → M6 (LFOV)
Out position: 55mm
DRZ: 0mm
CsI: 145mm
(the screen can be moved by small amounts to change the exact position where the e-beam hits, e.g., to avoid beam marks of the screen, etc.)
