- 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"
- FILS is at Z=1993.274
Changing the dipole settings
- It is important that the e-beam never passes through the CsI array (see Measure scattered (low-energy) electronsDump-table electron diagnostics)
- Call ACR for changing the main dipole
