Dear Marco,

One of yesterday's questions was:

     Does the magnet with the vacuum chamber installed, fit down
     the shaft?

The answer is maybe.  See AlumVacBox140925.pdf.  To be able to
lower the magnet including the vacuum chamber down the shaft we
would have to

     1.   move the small flange closer to the field clamp
     2.   have the plumbing and bus-work de-mountable.
     3.   move the big flange closer to the field clamp.

Moving the big flange closer to the field clamp will probably
complicate the design of the field clamp and complicate modifying
the clamp after field mapping.

We should

     1.   Check the physical dimensions of the shaft. [The shaft
          gets bigger about 700 to 800 mm down from the top.]
     2.   Design the water and DC connections so that they are
          easily removed and re-installed.
     3.   Design the magnet so that it can be assembled piece-by-
          piece at the bottom of the shaft just in case lowering
          the assembly whole does not work.
