Minutes of Fermilab MuCool Meeting 9/10/99

Scribe: Alan Bross

1. Lucien Cremaldi updated the group on simulations for the cerekov ID system
   for MuCool.  The simulation was done for 180 MeV/c beam momentum and included
   multiple scattering, beam divergence, and PMT QE.  The beam momentum was
   fixed and used: Pi 5%, Mu 80%, and e 15%.  Plots showed good separation
   between pi, mu, and e.  However for electrons from muons that decay within 
   the channel, these electrons had a tail in the pe distribution that could 
   fake muons.  This would be a very small effect for a 1000 m decay channel.  A
   cosmic-ray test using a water radiator and a 5" RCA PMT gave a yield of 12
   pe, half of what was expected.  This will be investigated.

2.  Ed Black gave an overview of work on the Title I Engineering Report for the
    alternating solenoid cooling channel, the short 15T cooling lattice.  The
    document will describe in detail what is required for the MuCool system and
    will include: vacuum, RF, cryostats, coils (15 T and bucking), the LeH
    absorber system, safety considerations, and quality assurance.  The report
    will be made into a MuCool note and posted for collaboration review.

3.  Al Moretti discussed the status of Lab G.  Recently an electrical safety
    walk-through was performed.  AC power has been run to the racks for the
    modulator and the modulator cabinet is approximately 95% complete.  There
    will be 3 control racks in the area and two are currently in position.  The
    klystron pulse transfer is in Lab G and will be installed soon.  A power-up
    test is expected in about 1 month.  There are still LCW water concerns due
    to the fact that the pumps are located in Lab D.  This issue still needs to
    be resolved.
