...
- Remove MO tower and YAG from the IP
- Remove ND filters / attenuator
- Remove glass window between compressor and picnicbasket?!
- Compensate timing for the change in effective path length
- long timing scan 10ps window around t0, 10fs steps, 5 per step (5000 shots ~< 10 minutes); GAMMA1 + LFOV + COMP_NEAR + PB_NEAR
find new t0 - 2D horizontal vs. time scan 100fs window around t0, 3fs steps (i.e., 30 settings) vs. 100 micron around maximum overlap, 3 micron steps (i.e., 30 settings), 5 shots per setting: 4500 shots (~< 10 minutes)
find new t0 vs. horizontal0 (position/time of best overlap / strongest non-linear signal) - 1D vertical scan (scan ~100 micron in 0.1 micron steps, 5 shots per step → 5000 shots (~< 10 minutes)
find best vertical position
change spectrometer setting such that the nonlinear signal can be seen clearly - repeat 2D horizontal vs. time scan with LFOV_LBG
Electron-spectrometer calibration
- Do a calibration scan whenever something is changed (either beam properties or magnet settings)
