<pre>As per Tony Liss'request, changed alcohol bubbler on CMP (top, bot, nwa, swa) from -5C to 0.0C.   Also changed alarm trip limit.  CMP is having alot of HV trips that can't be explained.   Hoping this helps</pre>

aT ABOUT 1:00 PM shut off liquid nitrogen flow into CDF.  Cut open LN2 tranrfer line by sub-cooler to install a tap to supply LN2 to the COT cold trap.  Completed weld on inner line and pressure tested it.  Currently welding up the vacuum jacket on the LN2 line.  For the cryo system: Dry engine in manual at about 1100 RPM and the wet at 315 RPM.  PVMF in manual at 77%. PVX! at 0%, PVX2 at 100%. PVNI, PVNS, PVXLN all closed.  For most of the evening, the lead flow valves were closed.  The plant stayed surprizingly stable.  FIMF was 17 - 19 g/sec all evening.

<pre>Water drops seen at 12:00 inside the bore of the COT on the EAST end.   The drops are seen at the intersection of the 30 degree section and the cylindrical section.   On the east side, the only two sources of water at this location is from repeater cards and from cryo condensation.   I do not believe the turbo is getting water at the moment.   I see no moisture on top of the plug or on the endwall per se.   I do see moisture in the drip tray of the control dewar and there is moisture on the lead flows as the result of our warming things up for this n2 work.   I have asked B+W to keep an eye on this.   IT should go away when we turn N2 back on.   If it does not, we will turn off the flow to the repeater cards and see if that helps.   Current drip rate is about 1 drop/5 minutes.   Note only one cable in one slot is showing water droplets.</pre>

LN2 flow restarted to CDF building,tube trailer valved in, recharged TSCLRLN vpt to 40psig. Welding is completed, all is normal thus far. All valves are returned to their operating mode. 
The Wet and Dry engines are in auto.
