We took the beam from 7 am, 24 h operation in three shifts.

We set up a new scheme for aligning the beam to the HED branch, which gives one X-ray axis downstream of the tunnel even if we operate at different angles of M1 and M2 (i.e. 3 to 2 mrad). This relies on a fixed M3 Tx position and was tested for 2.5 mrad and 3 mrad during the shifts. CRL3 in the HED optics hutch was aligned to the new beam postion, alignment of CRL2 in the XTD6 tunnel is still ongoing.

We tested most X-ray devices in the HED optics hutch and the HED experimental hutch and found them in good shape.

We tested and commissioned first time with the beam a new intensity position monitor at HED that was installed in the winter maintenance period in the HED optics hutch (inhouse design).

There was an issue with the M2 mirror feedback and we asked DOC to help us with that today already as we need to have a stabilised beam for the night when we are planning to do AGIPD and epix flat fileding. Work on that is ongoing.
