Subject: HED Summary 21.3. 

Got the beam, aligned it up to the TCC, mirrors in 3 mrad configuration, checked positions for the CRLs. Energy up to 500 uJ at 8.2 keV, 2 bunches. 
Feedback M2 PBLM-2 camera was UNKNOWN. Power cycle (just switch off >> on) solved the issue. Also, the screen was extracted. Insert the screen. However, the count is too low (30 counts) to make the feedback running. We found that the trigger timing for the PBLM-2 camera was off by 20 msec with unknow reason. Then we had >~200 counts. 
The beam jitter on Zyla was quite large (~1-2x beam width).

Installed and aligned CRL4a and b. Then we pumped IC1. We realized that the M2 feedback went off two times, this needs to be checked from time to time. Otherwise no big issues, beam is mostly fine, energy is also fine.
