X-ray delivery:
- stable at 120µJ, mostly 63 pulses
- 1:30h downtime
- checked some alternativ lens configuration to test for smallest focus
- changed nozzle of liquid jet. The old one was strongly tilted at low flow rates
- overlap between x-ray / liquid jet achieved
- first scans from pure water at different jet distances
Problems:
- still problems with AGIPD detector movements (Motor is a state that does not exist in Karabo, only a reset on PLC level seems to solve the problem for a short time)
- x-ray beam has hit part of the shielding resulting in some damaged pixels on the AGIPD. |
