Sample

Endstation

The in-air sample environment in 19-BM-D. The beamline vacuum terminates at the water-cooled Be window; a short rough-vacuum section protects that window before the Kapton window transitions to air, where the sample stage sits in the white beam.

Enclosure: 19-BM-D.

Note

The detailed sample-manipulator design and the future robotic sample changer are out of FDR scope and are carried as questions (STAGE-1, ROBOT-1); they expand as the endstation is commissioned.
