Telephone problems kept all off-site but Kahn disconnected.

Tom Kobiliarick reviewed the design of the line, describing the elements used,
the pion spectra and results of Turtle and
Transport.   The present line assumes 180 degree phase advance of pions over
the decay channel, roughly twice that for muons.
There was discussion of what parameters could be varied and how the allowed
beam apertures were determined.  There was also discussion of uncertainties in
the pion yield and how these might effect the flux generated.

Ed Black presented a first cut at what a linac / SC coil system would look
like in real space.  There was discussion of what the
real components TPC's Instrumentation, Cables, Pumping lines insulation,
windows and all other components would look like.
Al pointed out that the linac would require two input waveguides
5" x 10" and the exact orientation of these is not clear at this time.  There
was discussion of windows (ss/Al/Be), thermal barriers between H_2 and rf and
other cryogenic components.  Ed would like the dimensions of everything that
would be involved in the experiment to the extent that these exist, however
there seemed to be a feeling that in many cases these dimensions would become
available slowly, and they might evolve.  People should try to think about
real hardware and give him their best numbers.

Dan Kaplan. considered the LH2 absorber cell which would be 0.64 m long and
absorb 18-27 MeV/mu.  Note that for 10^13 mu's,
and 15 Hz this would be ~0.5 kW.  Evidently SLAC has used a target with a
large energy deposition.  The E866 target seemed to be a reasonable prototype,
and it used a 4.25 " dia, 0.003" Ti for a vacuum window and and this might
work for us.  He also discussed MS and straggling for LH2, Be, Ti, and Fe and
showed that the H2 dominates emittance growth in a reasonable case.  There are
a number of questions which were raised but not disucssed:  Rounded windows,
helical/straight path length, target cooling, muon impurities and window 
imbrittelment.

Steve Kahn reported some progress with coupling straight to bend sections of a
solenoid with reduced losses.
