The first multilayer is attached to a water-cooled nickel-plated copper
block with
InGa alloy.
The mount of the second multilayer.
Both multilayers were prealigned with a water level, and the Bragg
reflection was found quickly.
The first multilayer already shows some discoloration, trademark of the
He environment in the mono box.
For completeness a picture of the white beam slits, which were rebrazed
and cleaned by Jim Savino
just before the run, in order to fix a water leak.
