- Commissioning of KB mirror at 2.5keV progressed last week and will continue tomorrow.

General Announcement:
- Many summer shutdown tasks have been scheduled already and information has been sent to the groups with tunnel tasks.
- XO will not fully engage with tasks in the instrument Hall carried by the Instruments. Please contact XO if there are difficulties in organizing these works. 
- Be aware of date for potential power off: 22 June (MPS group runs upgrades that may trigger the emergency power off); 
- Be aware of date for hutch access restrictions: July 1st and 2nd (D3 will test interlock system in experiment hutches); 
3rd of July is a reserve date - please expect only limited access to the hutches due to this tests.
- Safety information: Desy is now recommending each person to take a FFP-2 mask for tunnel works to be used in case of close proximity work. 
EuXFEL will follow this rule: SRP has available masks and groups with tunnel activities can collect these masks with SRP
- A schedule for summer shutdown activities will be send soon to the readiness mailing list.
