Minutes from target meeting held January 25 2007 in 892-1-B09

a) Andrea asked when the polarization values for the weeks 40 - 41 will be 
available for the physics DST production.

b) Jaakko showed the draft for 40 mm three cell NH3 target. It was decided to
build the 40 mm cells. Drawing can be seen in:

c) Claude: to avoid sudden loss of negative proton polarization when the 
solenoid field is ramped down the plan is to use linear gradient along 
the target. This gives slope of 26 mT for one 60 cm long target cell.
The value is the same as was used in the SMC experiment with two target
cells.

d) Norihiro made COMPASS note on "Heat input into the polarized target material
with the hadron beam".

e) Kaori received new PC for the NMR.
