a) Condense helium-3/4 mixture on Tuesday morning. Ramp up the magnet.
Updated instructions for magnet in 
http://wwwcompass.cern.ch/twiki/bin/view/PolarizedTarget/PolTargMagnStart
Start polarizing up- and downstream cells noon. About -85 % reached.
Coil #1 signal small compared to others, maybe smaller filling factor.
Wednesday noon start to polarize the central cell. Too small helium-3 flow
in the beginning and some polarization lost from up- and downstream cells
due to warming up of the material. Ramp down the magnet on Thursday morning
and remove helium-3 from circulation in afternoon.

b) Kaori: coil #1 has only one thermal equilibrium calibration temperature
point. In case of PXI ethernet communication error empty NMR-file is written 
to the hard disk.
