How to edit the title slide
Upper area: Title of your talk, max. 2 rows of the defined size (55 pt)
Lower area (subtitle): Conference/meeting/workshop, location, date, your name and affiliation, max. 4 rows of the defined size (32 pt)
Change the partner logos or add others in the last row.

2. Layout of the beamline cooled bendable & cooled
Altogether 11 mirrors are allocated to guide the beam to all the experiments in SASE1, 2 and 3 beamlines.
