a) Jaakko: Update Siemens PLC drawings. The substation in the pump room has
many new modules for reading the helium-3 roots motor temperatures. The
digital inputs that were originally used to monitor the operation state
of helium-4 pumps are not needed any more due to pump upgrade. The control
room substation has two new unused modules. The target platform has unused
modules that were used for automatization of LN2 precooling of the magnet
in 2004.  

b) Calculate the target material data of run 2006 since this was missing
from the elog notes. See http://wwwcompass.cern.ch/elog/target_polar/197 

c) Kaori from Gerhard: irradiation tests of the Q-meter modules did not 
reveal any change in the NMR circuit operation. The dose was 100 Gy. 

New Q-meter modules could be tested during the thermal equilibrium calibration 
before the physics run 2014. 

Quote received for 150 feet of miniature coax cable UT034 to be used in 
the target holder. The model B not available and the standard cable has
silver plated copper clad-steel inner conductor (SPCW). This might 
influence the magnetoresistive behavior of the NMR circuit.
