Chan Kim | SPB | Shift summary | X-ray delivery
- 18.8 keV, 260 uJ pulse energy
Optical laser delivery
Achievements/Observations
- Experimental setup optimized, both instrumental side and PIXIE side
- X-ray beam focused to the PIXIE and transmission measurement was done with several different PIXIE operation conditions.
Issues
- No beam for ~4.5 hours due to ZZ.
- X-ray beam not found with IRDa InlineMic after focusing X-ray beam to IRDa sample plane.
- InlineMic Y motor is in error states. It has to be fixed during the day.
- upstream kapton window for the downstream vacuum pipe broken. The glue has become loose. No damage by X-ray was visible.
