Minutes - Mucool meeting - November 20, 1998. 

Paul LeBrun presented an update on cooling simulations with the new
(1.5m cells) Alt. Sol. Lattice.  The cooling performance is significantly 
better than the 2m cells. A 26m section cools 6-D by ~2.5x; compared to 
~1.75 x for the 2m cells with ~ same losses.

Al Moretti discussed the status of Lab G and showed drawings of the Lab G
area which indicated the need for removal of some old magnets and other 
modifications. A 805  MHz test stand would be assembled.
Al Moretti also presented an open iris cavity design (no Be windows),
with iris diameters varying from cavity to cavity, following the beam radius.

N. Holtkamp presented a 805 MHz cavity design with a traveling wave 
configuration; The design consists of open iris cylindrical cavities with 
coupling slots between cavities.  It is suitable for SLED pulse compression 
operation.

E. Black presented a first mechanical design for the 1.5 m cells.  The 
absorbers + magnets and rf form into a compact unit, with improved access 
to rf cells and cooling. 

Don Summers reported on the status of machining of copper cavities for the
low-power rf test stand. Machining of 2 cavities is in progress.
