X-ray delivery

• 18.8 keV, 260 uJ pulse energy

Optical laser delivery

• No optical laser

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.

Issues:

X-ray beam intensity was weak at 12.7 keV (100 uJ), so we decided to use 10 keV

1) BKR calls SUN11h20 and informs about issues with the SA1 SRA. Motors in ERROR.

2) Additionally, there was this morning a fire alarm, where in one rack (SASE1 rack 1.1 in XTD2) the gas extinguishing system was triggered, see also https://ttfinfo.desy.de/XFELelog/show.jsp?dir=/2025/03/19.01_M&pos=2025-01-19T10:22:14

PRC investigating.

BEAM STATUS: SA1 is still lasing at 1100 uJ at 9 keV, IMGFEL is inserted and beam visible. XGM and imagers operational.

• All SA1-SRA MOTORS (SA1_XTD2_PSLIT/MOTOR/) in sa1_beckhoff_mov are in ERROR and cannot be reset.
• Same for SA1_XTD2_FLT/MOTOR/TARGET (in ERROR and cannot be reset)
• SA1_XTD2_SRA_SLIT/MDL/MAIN in ERROR
• Same for SA1_XTD9_IMGPII45/MOTOR/NAVITAR_FOCUS and _ZOOM, but these karabo devices can be RESET, however Hardware State remains ERROR. Hardware interlocked.
• Same for SA1_XTD2_PES/SWITCH/G1_OK and G2_OK, but these karabo devices can be RESET, and the Hardware State here is then OFF. Hardware REGION is normal.
• SA1_XTD2_PES/SERIAL/V101256D and SA1_XTD2_PES/VALVE/V101256D in ERROR, can be reset. the STATE = NORMAL.
• Also found in ERROR: SA1_XTD2_WATCHDOG/MDL/STOP2_BKG_IMGFEL (but can be reset, is stopped).
• BeckhoffPlcMonitor SA1_BR_SYS/PLC/MOV_PLCMON in ERROR, can be reset, Hardware state NORMAL.
• SA1_XTD9_MIRR/ACTRL/RZ in ERROR (not the other related motors)
• SA1_XTD2_PSLIT/LVDT/BLADE... all in ERROR, can be reset, then hardware state ON. Hardware error description: "PLC Error: Terminal is not operational"
• SA1_XTD9_MIRR/ASESN/RY and RZ in ERROR, can be reset, then hardware state ON. Hardware error description: "0xc009"
• SA1_BR_SYS/PLC/XFELO_PLCMON in ERROR, can be reset, Hardware state NORMAL.
• SA1_XTD2_DOOCS/CAM/OTRC_2615_T9 (DOOCS-to-karabo bridge for transmissive imager) not instantiated. I instantiate it, there are no issues, works fine.
• Everything OK with SA1 vacuum devices.

Actions for BKR to continue SASE tuning:

1. The IMGFEL image is oversaturated. Changing to BN. The beam is at (13.5mm / 4mm), while the handover cross is at (12.75, 5.22mm). Beam is clipping at the top SRA blade.
2. inserting transmissive imager (YAG). Beam is fully visible and centered at X=1045,Y=1140. Instruction to BKR to use this imager to shift the beam center, and then continue on IMGFEL.

Further actions:

1. Information to DRC (Bruno)
2. He will inform EEE-OCD to look into the issue and see what they might be able to fix without an access. 
3. If they find out an access is required to fix hardware in XTD2, we will request an access (probably not today but MON or TUE). 
4. A redmine ticket of DOC will collect the infos from DRC and EEE-OCD.

A similar issue at SA1 XTD2 rack 1.1 had occurred in November 2024, see https://in.xfel.eu/elog/OPERATION-2024/205

Updates MON morning:

• EEE made the access request and it was scheduled for MON 10am: #215916 - Suspected blown fuse replacement in Rack 1.1
