General notes:
- For all scans: add all scalar lists to the dataset
Initial e-beam parameters
- waist at PIC_CENT
- beta function: 0.5m
General preparation
- Remove everything from the beam path: Items that could be in the beam path
- Prepare radiation monitors: Radiation monitoring in sector 20
Recover Laser on MO_MAG
- Align laser to tunnel
- Move RP attenuator out, ND filters in
- Recover M1/M2 alignment using FrontView
- Verify that laser is back on MO
- First focal scan to verify laser quality
Recover EOS
- Prepare EOS: first polarizer: full transmission; camera/analyzing polarizer: maximum extinction
- EOS timing scan to find t0 for EOS:
Spatial Alignment: KES
- Align vertical: 1 micron steps, over 100 micron, 10 per step (1000 shots ~< 2 minutes); record both MO_MAG and GAMMA1
Align horizontal:
Timing YAG
- Find t0 using a) long-range scan b) fine scan (10fs-steps)
- Move EOS delay stage to see EOS and YAG timing simultaneously
- long scan (YAG + EOS): 5ps window around t0, 10fs steps, 5 per step (2500 shots ~< 5 minutes); MO_MAG + EOS
- fine scan (YAG + EOS): 100fs window around t0, 1fs steps, 25 per step (2500 shots ~< 5 minutes); MO_MAG + EOS
- jitter scan (YAG + EOS): keep timing at t0, take 2500 shots at the same position; MO_MAG + EOS
Collisions
- 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)
