a) Meeting with PH/DT to discuss about the replacement of the old helium-3 
roots motor thermal protection relays. 10 new relays Ziehl MSR220K ordered and 
received.

b) Offer for new helium-3 roots water flow spinners EUR 71/piece from Apollo
Flow.

c) New target holder end caps made from glass fiber received.

d) Integrate the areas from the empty target cell calibration November 26 - 
December 1 after the run 2010. Coil #10 did not record any NMR signal during 
this calibration. See http://wwwcompass.cern.ch/elog/target_polar/110 

e) Fabrice: LHe delivery delayed by two weeks from the original planning.
This includes also the maintenance work on the helium-4 pump system. Empty
target cell calibration before the run was discussed.

f) Yuri: test cooling water flow to the EIO tubes for 3 days. Install the new
EIP counter on the microwave table. Repair of the old EIP counter was
discussed.

g) Reading of the PLC parameters is done in frequency of one second from the
COMPASS DCS system. For the LabVIEW it takes about 3 minutes to read all
the parameters including the resistance bridges for the thermometers. The 
Oracle database is updated with the new values every 15 minutes from the 
LabVIEW.
