The lead-glas/pair setup is a yellow crate which is usually moved out of the
beamline, when the telescope has been used to adjust detectors along the
beamline. This setup is of vital importance for the data-analysis, because
it allows measurement of the tagging efficiency.

Usually the set-up should be mounted in the correct position, if not, this
should be done, before any measurement is started:
Look for a crane-set and put it around the yellow rack of the setup. Put it
together into the crane-hook. Lift the setup carefully. On the lower end of
the setup, there are two needles, one at the front-side and one at the
back-side. On the floor you see a line
which is parallel to the beamline. Adjust both needles of the
setup onto this line. Pay attention, that under every foot of the setup,
there is a black rubber-plate. This is necessary to isolate the setup
from the floor and prevents groundloops.
