a) The internal water cooled heat exchanger for Pfeiffer roots pump WKP4000
was received on Monday. See

http://wwwcompass.cern.ch/elog/target_polar/198

b) Install pt100 temperature sensors to helium-3 roots pump water cooled
heat exchanger outlets. These are called TWHE4, TWHE7 and TWHE23 in COMPASS 
DCS system. The TWHE4 is measuring the WKP4000 pump bottom plate temperature
without heat exchanger now.

Connect pt100 sensor to the NMR rack Q-meter shielding box below target 
platform on Jura side.

c) Kaori: NMR system tuned with short extension cables. The cooling unit
with water pipes for Q-meter boxes and NMR cables installed and tested.
The NMR rack needs to be fixed on the concrete floor before magnet is 
ramped up. The polarization data is already sent to MySQL database. Preparing 
to send data to the DCS system with a DIM server. Communication with the 
magnet system needs to be tested.

d) Fabrice: problems in productions of LHe. The helium liquefier had several
technical stops during the week due to water cooling, power cuts and
problems with isolation vacuum.

e) Norihiro: the position of the DR helium-4 main valve and helium-3 main 
valve can now be seen from the DCS system. 

f) Johannes: one week delay in LHe delivery.
