  MUCOOL meeting is thurs/fri, 11/11 - 11/12
  There will be a front end meeting M/T/W on the 13th floor
  Cooling theory will be on thurs

  Ed Black showed part of a plastic model which will be made to demonstrate
the construction of coils, target and rf systems 
in the cooling system  This will be made at IIT and on display
there for a while, but it could also come to Fermilab as part of
a display.  This model will be done in a few months.

Ed and Paul are working on the final stages of lattice a lattice
design for cooling, where the mechanical and theoretical factors
are both harmonized.


  Mike Zisman reported that an initial calculation of a cooling
channel from front to back is starting to work.  This is for the
neutrino source.  The numbers are not yet optimized yet but there
are at least numbers for everything, and there is a clear plan for
optimizing things.

Greg Penn has been developing an analytic analysis for cooling
in a form like the Courant-Snyder method.  This will be eventually
folded into ICOOL.

There is no longer much disagreement between ICOOL and DPGEANT,
and the differences seem to have been due to setting the input
parameters of ICOOL to inappropriate values, and other minor
problems.

The calculations are not there yet but the gross features of a
complete picture are beginning to emerge.


  Mary Anne Cummings is beginning to look at the hydrogen target
construction, and the issues involved in getting the system
past the Fermilab safety committee.  There is a question of
how one could test 1.E12 particles in such a target,  (p's,
e's, etc.?)  How does one measure what is happening inside,
(thermocouples, Schlearn, ??).  How can we measure the density
fluctuations, how much can we tolerate?


  Jim Norem reported some new (but not yet final) data on x-rays
from a rf cavity at Argonne.  These were compared with the maximum
flux allowed by energy conservation and some estimated limits that
the TPC's could tolerate.

  
  Steve Geer continued the discussion of the long term R & D plan
which would also apply to the neutrino source.  The primary subjects
of discussion were collider relevant cooling problems.
