The DAQ gets data from AGIPB, DOOCS, Karabo, labelled with train-ID and the labeling have to be checked for consistence. This is not a new issue and has to be addressed 
in the frame of data reduction. 
- A clear independent signal has to be also checked. P. Gessler says it is needed to get various patterns for a complete understanding. A clear strategy to develop and 
address has to be made. 
- S. Aplin will overlook the efforts among different groups.

Relaxation control network: 
- CTRL and XO remind the groups to submit the planned activities on e.g. scenes, projects, until Fridays. 
- For next week case: please limit any hardware change. Reason is the current limitation on the physical presence of staff. 
Groups will support only emergency and priority tasks. From May 4th the situation will be different. 
- However, we do not want to stop any progress on activities. This also includes work on Karabo that affects critical work like VAC in tunnels.

Tunnel access for the coming weeks:
- A scheduling plan will be made due to the restrictions of allowed people working on tunnel at the same time. 
Plan will be made in order to respect safety rules and minimize number of people working in tunnels. 
- Tunnel access will be a first agenda point from next week.

General:
- For next meetings, we will continue with the small report from the support and instrument groups.
- Tasks to happen in the hutches are decided by the groups. XO/PMO plan tasks in tunnels.
- We encourage groups to start as earlier as May 4th the tasks which were originally planned to be conducted during the summer shutdown. 
If it needs tunnel access, then one must respect the coming schedule.
- XO is looking together with Desy on all tunnel activities. A schedule is being prepared and will be communicated to the groups as soon as possible. 
- In case of delay of activities due to e.g. excess of people in tunnel, prioritization will be made together with XO and Desy.

CTRL:
- In SA2/HED few interlocks are protected and not altered. CTRL needs to re-start the HEDloop1 and HEDcryo loop and SA2 EPS loop. It takes about 5-10 minutes without PLC 
restart.

LAS:
- SA1 and SA2 PP-lasers are fine;
- In SA3 still ongoing due to small problem of missing train-IDs in ADC cards. Consequently, no DAQ data can be taken for SCS and SQS. 
Nevertheless, the laser is ready for SCS use (not yet available to SQS).
