Started M9B MYCOM helium compressor circulating helium through system last 
Friday. Right hand purifier was regenerated previously, LN2 fill system 
started and flow started from buffer through purifier to low pressure 
return line to compressor. Left in this mode over the weekend. Curtis came 
in on weekend to add new full LN2 dewar to purifier.

Started // warm return cooling Monday.
Tuesday morning solenoid temps about 35 K and TI121 about 35 K  so 
switching to // cold cooling.

Note:

PDI 104 guage is very slugish to respond, needs to be replaced or cleaned.
TI148 and TI149 need to be recharged with helium, they do not work yet.
TIC121 may be reading too high a temperature, try to verify it with TE147 
before JT effect begins. Now TI121=20.7 K   TE147=25 K   HIC155 is full 
open still.
LIC108 is reading too high, reads 22% LHE but really is no LHE at this 
point.
