Beamlines:

http://www.cells.es/Beamlines

* Core Level Absorption & Emission Spectroscopies (CLÆSS)

• Programming of the beamline's control software has started.

* Materials Science and Powder Diffraction (MSPD)

• Bake-out of the main optics is currently in progress.

* Macromolecular Crystallography (XALOC)

• Site acceptance tests (SATs) of the automated sample changer (CATS) have been passed successfully.
• The contract to procure the main data collection detector (PILATUS 6M) has been signed with DECTRIS.
• Optics metrology of the Vertical Focusing Mirror has been performed.

* Non-Crystalline Diffraction (NCD)

• The white beam slits, xbpm, high-resolution fluorescent screen, and sample table with five degrees of motion have been installed and/or received. These four components have passed their Factory Acceptance Tests (FATs) and two of three of them their SATs.
• Bake-out of sections along the beam line with equipment available has been carried out.

* Photoemission Spectroscopy and Microscopy (CIRCE)

• Mirror chillers have been tested.
• Bake-out of several beamline components (diagnostics) has been performed.
• The first image with the PEEM has been taken.

* Resonant Absorption and Scattering (BOREAS)

• The first optical sections of the beamline are all now in Ultra High Vacuum (UHV) (p < 10^-9 mbar).
• We are continuing with the bake-out of the optical sections downstream the monochromator, including the gas cell which was recently installed.
• The computing network installation is finished and the control system is being installed.
• The first phase of the fluids installation is completed.
• The 3 superconducting coils of the XMCD end-station have been successfully tested by Scientific Magnetics, which will proceed with their integration in the cryostat.
• The contract for the sample cryomanipulator of the RSXS end-station (MARES) is about to be awarded.

* X-Ray Microscopy (MISTRAL)

• Bake-out is being carried out to reach working vacuum at the end of September.
• In vacuum motor tests of the mirror are being carried out.

• SCW30: SATs have been passed successfully. Maximum reachable field is 2.2 T and long-term stability has been tested for a deposited power on the vacuum chamber of 20 W (estimated in real case to be always lower than 10 W). Helium consumption is null even in the case of a single quench because cryostat is working at 0.5 bar pressure below atmospheric pressure.
• IVU21: New time schedule has been fixed by manufacturer. Delivery of IVU #1 will take place at the end of July. IVU #2 will be delivered in mid August.
• 2nd phase beamlines: a rough conceptual design of the electromagnetic undulator for LOREA beamline has started.

• The Storage Ring is now closed, from a vacuum point of view, and installation of the interfaces (piping and cabling) is proceeding at a good speed. All the front-ends have also been baked out.
• Meanwhile, we are working very closely with the Controls Group and we are finalizing the preparations for the Booster commissioning scheduled to start on July 19th.
