Description
We make a brief overview of activities related to the geometry of
the main dipole and the main quadrupole. The blocking of the central
support of the dipole has contributed to the stability of the cold
mass in the cryostat. Work on the measurements of the spool pieces
(magnetic and mechanic) has been carried out. Collection of
measurements on the quad axis measurements in data bases has been
made and a first report on these measurements can now be made. Work
on the vertical alignment has given results for the position of the
ends of the dipole.
We will give a review of the results of the measurements and the
analysis made so far: the shape (the axis), the interconnectivity
and the spool piece positioning. We will also give some results for
the cold warm relations. The effect on geometry of interconnection
and the aperture and the feed-down related to shifts will be
discussed. First results on the long term stability and related
issues will be mentioned.
