Minutes of MuCool meeting 12/4/98

News:  The collaboration meeting will take place next week -- 
Mon thru Wednesday in the Penthouse (2nd floor of the Booster West Tower.

Thornton Murphy:

The AIP funds to support the Meson 120 project were postponed into FY01.
This covers conversion of beam transport upto the Meson Area. It would not 
include coversion of MCenter and MPolarized for MuCool. If funds are 
available on 10/1/00, beam to Meson could be available about one year later.
Some schedule conflicts exist in the TeVatron tunnel at F17 to A0,
since access is allowed only when beam is not running. Current goal is
for beam to Meson on 10/1/01.

A kicker currently used in the TeVatron may be available for the Meson
transport system to generate the 15 Hz beam, each pulse of about
20 microseconds duration. This matches well into the warm cavity
design, which will be limited to about a 15 microsec lifetime.
This is about a factor of two reduction from the cold cavity design.

MuCool will have to compete for space with 3~4 other groups in the Meson Area.
PAC review of these proposals has not taken place at this time, but within
the next year, we might expect to see the experimental program evolve.

Dan Kaplan:

Has made several interesting simulation runs of LiH cooling channel
and the affect of windows on cooling properties. It remains uncertain
whether a separate beryllium window will be used for the RF cavities.
These studies lead to a reassessment of the required diameter of
the LiH absorber -- a five centimeter radius may be sufficient.

Action items -- Explore exotic windows; resolve RF cavity window
and its inclusion into cooling design. A new program at IIT may
provide for a graduate student in mechanical engineering to 
work on the LiH flask.  NASA may fund this program.

Steve Kahn:

A bug was found in the field maps.  Correcting the bugs will affect 
the field quality at the transition regions. New runs will be needed
with the bugs fixed. Expect to hear more next week at the 
collaboration meeting.
