COMMENT ON SAM 25 - Replace SLM0R02 Imager
Log Number: 4472314Logbook(s): Body:
Attempted to find the SL with Tune Mode beam to the ILD without success. Found a vertical strip (see Atlis attached image) at 7 mm-X, 7mm-Y & 25mm-Z. Found a slightly tilted vertical strip when moving 1mm in either direction with the X axis. This suggest that the image at (7,7,25) has only a Y axis error but no addition image was found steering in Y. The steering suggest that the light is coming from inside the vacuum chamber but the image persists without ebeam and with the next upstream viewer inserted. There are light blocking covers from the viewport to the camera.
Beam As Found: Before Tuning for 0L03 Match

Injector Optics Troubleshooting
Log Number: 4472309Logbook(s): Entry Makers: samariBody:
We started today with troubleshooting phasing with Max. He verified phases on the buncher and the booster, with small changes in both (~1 degree on buncher and R027, 3 degrees on R028). Optics still did not reproduce, but no anomalies were found. I spent some time to check centering before Reza had time.
Once again, I redownloaded the last all save that had a good known solution, and it unfortunately still did not reproduce.
Next, I met with Reza and tried to troubleshoot further.

Confirming IHA0L03 Configuration
Log Number: 4472306Logbook(s): Entry Makers: bschaumlBody:
We were initially confused about whether our quad scans were looking at the right harp wires and decided to double check, and it seems that everything is correct; X is X and Y is Y.
First, we adjusted optics such that we would expect a larger Y sigma, which resulted in the beam spot and scan in Fig's 2 and 4. Then, we ajdusted optics to produce a larger X and smaller Y sigma, which was borne out in the beam spot and harp scan in Fig's 3 and 5. The sequence of optics adjustments and harp scans is shown in Fig.
