Minutes of the 30 Oct 98 Muon Cooling meeting:
Scribe: Tom Kobilarcik

0.  News:  Steve O'Day is leaving the lab.
1.  Ed Black has completed a first pass drawing of Palmer's latest 15 T 
    matching-coil configuration, and has sent e-mail to Palmer to confirm 
    that his rendering is correct.  Palmer and Black will iterate on 
    engineering versus physics constraints.
    Should run Tosca to roughly check Palmer's calculations.
    Current module is 209 cm long.  Will require a 220 mm penetration for RF 
    feed.  Moretti will check this number and calculate penetration for feeds 
    on opposite sides.
    It may be possible to eliminate one window between the RF cavity and 
    hydrogen cell.
2.  Steve Kahn showed simulated tracks through TPC.  He is trying to 
    understand resolution.
3.   Jim is working on liquid lithium lens.  For beam transport, is using two 
     lens minimal focusing at as low a momentum as possible.  Has a first 
     iteration of liquid lithium lens pressure vessel.
     Four-step program for first overall design has been proposed:
     1.  provide a self-consistent design.
     2.  experimental program to see what breaks.
     3.  build muon cooling experiment.
     4.  build one for muon collider.
4.   Ray Stefanski summarized current work on CERN pulsed power supply.  Need 
     a 40 by 30 foot area, probably double when controls, etc., are included.
     Possibly use Lab G, PE4, or Lab E.  Currently pulses at 0.5 Hz, will 
     require rebuild for 15 Hz -- it may be better to use AP0 or NuMI supply, 
     or build a new one.  A decision needs to be made.
5.  Paul LeBrun is determining if beryllium windows can be removed from RF 
    cavities.  He is determining his model as follows:
     1.  remove material to eliminate scattering.
     2.  remove radial dependence of field.
     3.  decrease voltage.
     He is testing each step using a perfect traveling wave, and looking at 
     non-decay 6D cooling factor.
