Bob and Aseet closed the door of the tent and this triggered the trip (collision hall air pushed to the baggie).  
They are going to test the dehumidifier system now. It is not unlikely that we will have a trip again, just in case, we have changed the setpoint to +0C (SVX) and +15C (ISL) while tests are going on.</td></tr></table>

<h3>Alpha-Numeric Pager F.U.B.A.R.ED</h3> 
After returning home from the gym, I noticed that the pager was not on, and wasn't turning on. Ignacio instructed me on resetting it by reversing the polarity of the battery for a few seconds and then the pager turns back on. When it does, it sticks on the "FLEX ALPHA PAGER START UP" screen with the "S" in the upper left hand corner blinking. I give up. Ignacio is looking into it.

Yeah, that's right. The auto-dialer will hit up the cooling pager (that's me this week...) and the cell phones. Why do we have this silly alpha-numeric thing again?! It's very difficult to flip tires with it strapped to my gym shorts...

This reminds me that on last saturday around 4 am this thing slept
(and let me sleep too :-) through the PS logging problem, which 
Ulrich reported about, and didn't receive loads of messages! Since
it was ON in the morning, I am pretty convinced that it needs to 
be exorcised, if we decide to keep using it :-) Oh yes, towards 
the middle of the last week it went dead and I had to replace its 
battery.

<center><h2>BORE work begins!</h2></center> 
~09:30: When it rains, it pours: 
<ul><li>SVX sono-alarm caused by an over-pressurization of PCE line. In bringing the nitrogren line offline, closing the PCW line first forced *way* too much flow (no regulator?) through the PCE line, thus tripping QUADLOG on over-pressure. When QUADLOG trips on over-pressure, it will close PV-CHSUP and trip off the racks. So, there is once again the unfortunate 10 minute wait time with silicon turn on (not a problem here) and then there is the problem with clearing the QUADLOG errors. Ask cryo (Bill Noe) for help with this, also Ulrich seems to have a pretty good understanding about where in the QUADLOG logic to look to see where the errors are still latched.</li> 
 
<li>While this was going on, ISL was feeling lonely, and tripped on low flow. This was probably a result from the disturbance from the SVX port card lines. I saw that this was the case from the interlocks page on iFix where "Chiller ON" was red and we also had a "Low Flow" global alarm for the ISL interlocks. Thinking about it for a minute, I went to the global alarms page for damage control, and saw a whole bunch of "@@@@@@" where there should have been values... I saw Ignacio and he and I ran downstairs to give the chiller a swift kick in the ass with a 5# wedge of steel (that felt nice), and continue our debugging. Why the gargled iFix values, you ask?</li> 
 
<li>Seems that cryo though that it was a good idea to reboot the S3 machine (later we find it *apart* for a replaced hard drive, this is another story), and I have a keen feeling that this is the machine responsible for publishing chiller information to the iFix nodes for our viewing pleasure. We still want the monitoring. Periodically throughout the morning, other values (temperatures, return temps, etc.) were missing as well as other machines were rebooted for some random Windows security patches and updates.</li></ul> 
 
<p> 
~11:15 We convened at the 3rd floor oval table for a pre-bore pow-wow to review the procedure and to make sure that we were all on the same page with the work procedure of the JHA. We all agreed to have both the "SVX"/"ISL" and "tent" dew point real time plotters open both remotely on Bills iFix latop, Jose's laptop using the remote desktop from svxiicon, and on VNODE2 for me in the control room. We still have the tent temperatures in degrees Fahrenheit, so some creativity is being used in reading off the proper dew points. 
<p> 
Also discussed was future operating procedures with the techs and any problems are to be  discussed through Bill Noe, and although some overlap and multitasking are necessary, occassional oversight happens (i.e. missing iFix information from the S-nodes). 
<p> 
At the conclusion of the meeting, it's agreed that after lunch (12:30-ish) bore work begins. 
 
<p> 
~13:25 Peter phones from the west bore, saying that the east side has been slit, and the reduced nitrogen flow into the west silicon baggie has begun. I have enabled the "West Flow Alarming" by logging into iFix, and going to the Process Systems tab, and clicking on the alarming button provided. The HVAC page has a lot of new added features for this job; it's quite nice. 
 
<p> 
~13:50 Doug calls us from the bore, and the east baggie is to be slit a bit more to look for the Cilran tubing. They were able to cut the tubing and make a video with the boroscope. Upstairs, I engaged in more vigilant dew point watching, but didn't see any temperatures venture past -11°C inside the baggie, so we stay in more than a 5°C window from any miserable dew point trips. Nice work. 
 
<p> 
~14:40 <b>The (semi)end-of-the-world!</b> Time to evacuate the control room for the non-existent tornado. I phone down to the bore to let our friends know that we won't be in the control room, but instead in the stairwell until further notice. Back one *hour* later. 
 
<p> 
~16:00 Everyone is back in the bore, and Jose gave me the update: the boroscope video for the supply side was finished (work to start tomorrow morning) and they are working on the inspection of the return Cilran line; I am unsure if a video is available for this inspection. 
 
<p> 
~16:30 Two quick HVAC alarms for the east and west "AC_E(W)_LO_TENT" for some tests. Once these tests are finished, work in the bore is completed for the day! Peter ensured me that the Nitrogen flows are back to their nominal over-night values. 
 
<p> 
In the morning, (08:00!) the team picks up where they left off, beginning the expoy repair of the supply line, finishing the visual inspection of the return line and hopefully a start on return line repairs. 
 
<p> 
The bore work finishes up, and conclusions are to follow. Many thanks to our collision hall crew: Ken, Doug, Peter, Jose, Ignacio, Del, Bill Noe & Comapany and all of our technicians.

As Jennifer mentions above: in preparation for the leak test, he turned down the nitrogen to one (West?) side, forcing everything to the other (East?) side. That could explain the spike in the pressure. One thing we should follow up on is an easy way to reset such a trip and re-open the pneumatic valve.

That the dew point fall is not bad, but it is weird that they have fallen so fast, around 4 hours after we closed the baggie and we restarted the normal nitrogenflow. Now the dew points  are at their nominal values  when the silicon baggie is sealed.  A leak has closed?

<!-- Comment: Thu Aug 23 21;52;15 comment by...Ignacio -->
The tent dew points are flat.

<!-- Comment: Thu Aug 23 22;02;26 comment by...Ulrich -->
Weird indeed. Tomorrow we want to check if the drop in dew points is due to a drop in humidity or temperature.

Around 21:15, the dew point at the East Silicon Baggie window dropped because the humidity at that point dropped. A little later, the dew point at the West Silicon Baggie window increased and saturated at a value higher than usual. The reason seems to be the residual humidity of around 5% inside the Silicon volume, despite the nitrogen flush and the tent.</td></tr></table>

<!-- Comment: Fri Aug 24 09;19;47 comment by...Ulrich -->
Just spoke with Del about this. To him it looks like the seal around the small hose to blow dry air into the Silicon baggie from the West isn't too good. He will have a look at it this morning.

Ken and Doug have inspected the return first thing. Then tried scratching  some of the brownish stuff. I understand it would not come out. They are doing the rear ring pressure test right now.

Dell tells me that the <b>N2 flow sensors to ISL</b>  (east in particular) have a large hysteresis effect. One can go down to 30-35 in the flowmeter once the alarm has reseted (close to 50).

<h3>Bore Access for Leak Repair: Day 2</h3> 
 
<ul> 
 
  <li><b>8:30</b>: Ignacio and Ulrich have updated the iFix pages on 
  the bore iFix PC to display the values correctly in &deg;C rather than 
  &deg;F 
 
  <li><b>8:40</b>: Del has turned down the nitrogen flows to SVX and 
  ISL. Jim Loskot changed the alarms page so that the alarm on 
  nitrogen flows can be silenced (and more importantly unsilenced) by 
  anybody with a CDF iFix account. Del notes that the flow switch that 
  triggers this alarm has quite a hysteresis. To clear the alarm, at 
  least 48 SCFH of flow are needed, but the alarm will only kick in 
  again below 12 SCFH. 
 
  <li><b>8:50</b>: The flow to the West baggie is above alarm limits, 
  so we enable the appropriate alarm. It took about 10 minutes from 
  the time Doug called to the point when the flow switch really 
  displayed ON for the flow. 
 
  <li><b>9:45</b>: The dew point approched -10&deg;C for the first 
  time. They are around -12&deg;C to -15&deg;C now. Another spike 
  about 10 minutes later, going up to -9&deg;C. That happened around 
  the time when Ken and Doug inserted catheters into the cooling lines 
  to confirm (once again) the leaks. This time they applied Snoop to the 
  balloon of the catheter to check if it seals properly. 
 
  <li><b>10:50</b>: First round of epoxy on the rear manifold of the 
  East supply manifold. Problems because epoxy is too stiff. The 
  earlier problem with the sensitive dew points is solved by opening 
  the upper flap of the cutout in the COT baggie. Bob Wagner pointed 
  out that the COT baggie has a connection to moist environment 
  through the cable slots that normally serve as an exhaust for the 
  nitrogen. If we let the dry air from the dehumidifier drive the 
  humidity, we are better off. 
 
  <li><b>11:30</b>: Lunch Break 
 
  <li><b>12:30</b>: Second round of epoxy. Solution for stiff epoxy 
  problem: heat epoxy with small halogen lamp. Epoxy goes on 2nd tube 
  of rear East supply monifold both ubes of the front East supply 
  manifolds. 
 
  <li><b>14:00</b>: Create epoxy "dogbone" by blowing through Cilran 
  tube. Very little resistance felt, so it is unclear if the dogbone 
  worked. Third round of exoxy goes to second front East supply 
  manifold. 
 
  <li><b>14:35</b>: Proceed with rear East return manifold. The left 
  tube looks worst. Pit is so big that you can see the brass tube drop 
  into it. Applied more epoxy on that side. Need to go back and check 
  if the pits are properly sealed. 
 
  <li><b>15:45</b>: Apply epoxy to front East return manifold. Plan is 
  to continue tomorrow with epoxy on the (almost unpitted) rear East 
  return manifold. Doug also notes that we should bring "more alcohol" 
  tomorrow... 
 
  <li><b>16:00</b>: Clean up things: shut down flow to Silicon baggie 
  from the West side and re-enable overnight nitrogen flow. Note that 
  the flow has to be cranked up to almost 50 SCFH to overcome the 
  hysteresis of the flow switch and thereby clear the iFix. Everybody 
  is out of the hall by 16:30 or so. Peter, Ken, Jose, Ignacio, and 
  Ulrich keep their keys for tomorrow. 
 
</ul> 
 
So overall this was a very successful day for the bore crew. Thanks to everybody: Del, Peter, Doug, and the epoxy master himself, Ken.

Saturday morning report: The plan is to continue today with an inspection of yesterday's work and work on the last remaining tube. 
The dew points have been stable overnight, no fully drops. Yesterday we forgot to unsilence the alarm on Silicon baggie nitrogen flow before we left. We should have a checklist.

SVX conductivity went above 16 this morning around 6:30. Ask  to change resin again on Monday. May cool down a bit when we finish working today.
<!-- Author: Ignacio -->
<!-- Comment: Sat Aug 25 09;40;46 comment by...Ignacio -->
The SVX conductivity is 16.5 as read from the controller in alcove. A sample measured at 10.6 C gives 10 muSi/cm and pH 4.23. This will be remeasured at room temperature to be consistent with Bill's measurements. These show a downward trend from pH 4.9. 

<!-- Comment: Sat Aug 25 09;55;09 comment by...Ulrich -->
<pre>Bill Noe called in and asked us to check if the SVX resin bed actually has flow. We will check later today and make a note in the e-log.</pre>

<!-- Comment: Sat Aug 25 11;07;42 comment by...Ulrich -->
I have just checked the resin bottle. The valve with the pneumatic actuator is open, and it is cold, so I would expect that it has flow. I have found the insulating cover of the bottle removed and the bottle slightly leaking. In any case, a resin exchange on Monday seems to be a good idea.

<!-- Comment: Sat Aug 25 12;46;06 comment by...Ulrich/Jose/Ignacio -->
We are cooling down SVX to -6 until Monday.


<!-- Comment: Sat Aug 25 14;31;16 comment by...Ignacio -->
I have re/measure the sample taken this morning. The pH is 4.29 at 18.5 C. The conductivity was 26 muSi/cm, but this is probably wrong because of my previous pH measurement. The controller read 18.5 muSi/cm in the alcove.

<h3>Bore Access for Leak Repair: Day 3</h3> 
 
<ul> 
 
  <li><b>7:50</b>: Ken has turned down the nitrogen flow to SVX and 
  ISL. ISL flows did not go into alarm this time. Checking again 20 
  minutes later, ISL flows are in alarm. Reason: Ignacio checked, 
  found the ISL flows still on, and turned them off. 
 
  <li><b>8:20</b>: People enter collision hall. The crew for today: 
  Ken Schultz, Peter Wilson, Ignacio, Jose, Ulrich. 
 
  <li><b>9:40</b>: Update from the collision hall. The pressure test 
  still shows leaks, but they are much less severe than before the 
  repair. Currently, Ken and Peter examine the tubes with a right angle view 
  scope to check for remaining leaks or imperfect coating with epoxy. 
  A rough estimate for the rate of rise is 1 psi per minute. 
  In the course of doing so, they produced two spikes in the 
  East Silicon Baggie dew point, the latter one was -8&deg;C. 
 
  <li><b>10:00</b>: Break and discussion: The inspection videos show 
  that not all pits are covered well with epoxy yet. Yesterday's big hole 
  seems to be closed, but there is still a pit that can be filled. 
  Ken will apply more epoxy on all tubes. 
 
  <li><b>10:50</b>: The <tt>/usr</tt> partition on b0sili01 was 
  completely filled up with bore movies. I have moved the movies to 
  <tt>/data01/TWikiData</tt> and created symbolic links 
 
  <li><b>11:50</b> Ken and Peter are done for today. They deposited a second 
  layer of epoxy on the ISL PCE return manifold. The work will continue 
  on Monday with a pressure test and more epoxy to the supply side. 
 
  <li><b>12:30</b> We decide to run SVX at -6&deg;C for the rest of 
  the weekend. Alarm limits have been adjusted accordingly. We have 
  also changed the iFix warning limits for the West SVX and L00 vacuum 
  jacket temperatures from 17&deg;C to 15&deg;C.

The east sili baggie dew points have droppped  today at 4 AM. Also east COT dew point. The SVX conductivity is out of range (> 20 muSi/cm).
<!-- Author: Ignacio -->
<!-- Comment: Sun Aug 26 16;40;22 comment by...Ulrich -->
It occurred to me this morning that such a drop could be due to a change in the COT baggie configuration so that more dry air is blown behind the COT baggie.
