a) On Monday make inventory of helium-3/4 mixture. The relative amount of 
the two different helium isotopes were determined with quadrupole mass
spectrometer. The amount of both isotopes is practically the same like in
the inventory done 2009. Small amount of N2 was found from tanks #1 and
#9 while the other tanks did not have measurable impurities in the 
detection scale.

b) Yuri: cavity microwave input circuit needs to be partially reconstructed.
Measuring the microwave leakage between the two halves of the microwave
cavity. The conical cavity end piece is installed now. Use a testing 
microwave stopper inside the mixing chamber. The central cell microwave
feed through will be closed. 

c) Norihiro: the target control room wall was moved by two meters upstream 
to make space for the new microwave table position. The water valves and 
outlets that were on this wall need to be moved to a new position. Small
modifications to be done on the rack power cabling, but the "normabarre"
will stay as it is. One new rack for the microwave power supplies will be 
added. The floor needs to be modified for the mounting of the microwave table.
The new holes for the microwave guides between the control room and the
experimental area are ready. 

d) Michael: submit abstract to the PSTP 2013
