<h3>Today access: ISL East PC line</h3> 
Yesterday we found out that the leak is in the detector (not accessible from the manifold), but we also found a loose valve that could be fix and maybe improve the vacuum in the compromised line. In addition to the fix, we wanted to check if using a larger vacuum pump into the system to overwhelm the cooling line with the leak will give us enough flow to reach a point stable enough to run the system. The details are: 
<ul> 
<li> Shut down flows to East ISL + SVX PC 
<li> Close manual main Supply and Return. 
<li> Close all manual supply (return ISL E/W + SVX PC) 
<li> Replace valves (CCE2 that showed a dropping behavior and the valve that was leaking in the return line)  
<li> Open main return/supply 
<li> Open all manual supply (return ISL E) 
<li> Check the flows. Nothing changed so we decided to try the larger vacuum pump (with the detector isolated). 
<li> We tried to run with the new pump but the pump tripped almost immediately. The level of the air separator was to high with the improved vacuum. We took out 5 gallons of coolant. Even after taking out the coolant, the pump kept tripping so we powered to a different outlet. After checking that the pressure was better but not much smaller, we opened the detector.  
<li> Open all manual return (supply ISL E/W + SVX PC) 
<li> Check the flows and tried to get some flow in the ISL PCE. The test was unsuccessful and no flow could be get through the line. 
</ul> 
Next step will be to try to figure out if the leak is close to the COT face.

We went in again after the access was finished. We forgot two valves closed (CCE1 and CCE3) and we could not get any flow. We checked them but, probably the offset on the flow meter fooled us. The access took less than 15 min and we did not drop the interlocks.


<!-- Date: Tue May 15 19:38:31 2007 -->
We have switched off the big cooling pump after the system pump was put online.
<!-- Author: Ulrich/Ignacio -->
<!-- Comment: Tue May 15 20;58;27 comment by...Ulrich -->
Note that now there is no backup pump connected to the system. In the unlikely event of a failure in pump VP1-A, we would have to switch the stronger pump on by hand (switch on the pump).


<!-- Comment: Wed May 16 09;32;03 comment by...Ignacio -->
Looking at the history it seems that the big pump  got us a 0.7 psi drop on the east detector return pressure. (6.74 to 6.05 psi). The west went from 5.9 to 5.23.

<h3>East Bore Access: The Preparation</h3> 
In preparation for the bore access we have flipped the 5V enables and started to warm up SVX from -2&deg;C to 0&deg;C and ISL from 6&deg;C to 15 &deg;C. We have also put the AutoHocker to manual mode.  
<p> 
We realized that PSMon.exe had thrown an exception around midnight, complaining that it could not close the "SwitchOff Log.doc" file. The reason for this behavior is unknown. Neither is the disk full nor the file too big (76 MB). We moved the file to a different name and restarted PSMon.exe. The file got created newly, and the problem seems to have gone away. We could make it part of our reboot procedure to create new log files.

Since we may touch things in the East bore, I've tripped the flows to all of East ISL. The initial rate-of-rise test gives us the same result as before: immediate jump to atmospheric.

As it turns out, we have been fooled by yet another flow reading in ISL. CCW2 showed 0.9 lpm at 50% valve opening, but would not open further. As it turns out, the manual supply valve to that line was still closed. We quickly opened it after the BLM work, and now it is flowing just fine.

<h3>Bore Access: Half Time Report &mdash; Bad News</h3> 
Ken Schultz, Doug Glenzinski, and Warren Bowman started the leak hunt this morning by over-pressurizing the cooling lines inside the bore with helium. The helium sniffer was way to sensitive to detect the exact position of a leak, but there were a couple of joints that had not been sealed with epoxy and looked suspicious.  
<p> 
To locate the position of the leak, they pinched the Cilran line at a point upstream and downstream of the Silicon baggie while pressurizing the lines from the supply and the return side and checking the flow. Both tests had consistent results: Both the supply and the return side are air-tight. <em>The leak is inside the Silicon Baggie!</em>. 
<p> 
We re-convened to discuss the next steps. We agreed upon inserting catheters to the supply and return line. They blow up a balloon and have an active channel to insert air or liquid downstream of the balloon. This test will tell us if the leak is in the Cilran tubing, in the connection to the nipples of the manifold or in the manifold itself. We ran into problems with the catheters and need some new ones. Currently the crew is taking their lunch break and will continue aroun 13:30. Stay tuned.

<h3>Bore Access: Final Report</h3> 
The bore access was continued in the afternoon. Doug and Ken cut the Cilran lines close to the entry and exit points of the Silicon baggie and investigated things closer with catheters and borescopes. The idea was to stick the catheter down the Cilran line as far as possible towards the manifold. The catheter blows up and blocks the line so that the air-tightness of the manifold can be tested. After a couple of attempts to get close enough, the conclusion was that the leak is at the manifold. 
<p> 
The catheter tests were followed by a visual inspection of the manifold with borescopes. With a 90&deg; borescope, Ken and Doug saw something at the points where the manifold pipes are welded (epoxied?) in: for almost all of them there is some brown-colored stuff around the joint and something dark (more or less big) that could be a hole. The obvious interpretation would be that this is <em>corrosion</em> from the time we ran with high conductivity and low pH. On the other hand, Ken"s theory is that the "something" looks more like coming from  <em>erosion</em>, e.g. through turbulent flow and cavitation at the joint. Borescope pictures will follow. 
<p> 
When Ken and Doug had learned enough, the re-connected the lines they previously cut on the COT face. We opened the return valve to get suction on the bad line (and the SVX portcard line). Tomorrow, after the plug will be back in, we will cap of the return line, close  and tag out the manual supply valve and unplug the controller of the e-valve, so that the PCE line remains safely closed.  
<p> 
As the last step we helped Bob Wagner and Morris Binkley to remove the East COT baggie and put up a new baggie. As has happened before, this caused a dew point trip on the West side of the Silicon baggie, probably by some weird pressure diffences in the system. We recovered fine after the dew points came back down. Now all flows are re-estatblished and the minimum number of alarms are ignored.

<pre>It may be the combined effect of EROSION AND CORROSION; first the turbulent flow tends to remove the oxide layer which protects the aluminium from corrosion, then comes the corrosive action of the agressive medium.</pre>

Borescope pictures taken by Doug and Ken this afternoon. The quality of the pictures is much worse than what we saw directly through the borescope. What you are supposed to see is not Jupiter, but parts of the joints between the supply/return lines and the portcard rings. The light arcs are the rims of the portcard ring lines, the dark spots around that are the spots were the erosion(?) takes place.

After the successful checkout of SVX East, I changed the chiller set points to -6&deg;C (SVX) and 10&deg;C (ISL). I hope I ignored all the right alarms.

There was a cooling  trip when the 8 AM  meeting was starting caused by ISL PCE going atmospheric. It took out SVX PCE and ISL. We asked the cryo-op to change SVX set point to -3 C. The trip was caused by work caping ISL PCE but there was some confusion about it since we did not know that this work had already started.

BLMs and diamonds are back in! Ulrich remains in the collision hall working on the cooling line lock-out (to prevent and re-establishing of flow to a line with a big 'ol hole in it). I've plugged back in the BLM HV, and Ricardo is here looking at the diamonds. 
<p> 
As expected, plugging back in the HV for the BLMs "aborts the beam". So, I'll re-establish all of that, too.

<h3> SVX only configuration </h3> 
<p> We will run for the next store(s) with only SVX. We have made some changes in the configuration to be able to run in this way. In the HWDB we have put offline using the <i>CardEditor</i> crates b0svx06 - b0svx09 and crates b0fib01, b0fib03, b0fib05 and b0fib07. With <i> traceSilicon </i> we have generated the new <i>caenvolts.dat</i> file. This file has only enabled the SVX wedges. To prevent powering up the ISL/L00 ladders we have left the ISL/L00 <b>CAEN +5V disabled</b>. We have tested the configuration by issuing a ON command from the iFix page. 
<p> We have run in this way the system in a cosmics and in the physics <i>AAA_CURRENT</i>. Both configurations have been saved for an easy use of the ACEs. <i>Coldstart</i> configuration has been also modified.

<b> Friday evening ISL west cooling trip</b><br> 
I had closed a little bit ISL PCW from 55 % to 50 % since it was fluctuating on the upper pressure warning (13.3 psi).  It did not move much, but after 5 min the pressure was 12.2 and the flow was close to the lower limit (1.5 lpm). So with good will but bad judegment I  opened it in 1 %  steps with no apparent effect. In the 59 % to 60 % the e-valve opened a lot, to such an extent that I tripped ISL west. I reproduced this behaviour, so I think this e-valve is not in the best condition. It took me a couple  of trips to recover the flows. Now the all e-valves  are at the same appertures as before.   I apologize to the cooling crew for tripping the cooling without need.

<pre>MONITORING REPORT. I checked ADCMon plots for runs 242033 and 242041, there were a couple discrepancies between previous runs: SB3W6 L4, SB4W10 L3 (7 and 12% errors), and SB0W2 L1 in the second run checked. </pre>

A little more quantitative please! This was even worse than yesterday. The East Inner BLM got 40 Rad/min (twice the limit), and both West BLMs got roughly 20 Rad/min), at 184e30. The store looks sick in general...

One hour after this situation, the MCR performed a second scraping. Now the loses are correct and the silicon, turned on. </td></tr></table>

<pre>STORE: 5450
INITIAL LUMINOSITY: 110E30
SVXmon and SVT SPYmon CHECKED AND CORRECT.</pre>



<!-- Date: Mon May 21 09:12:09 2007 -->
<pre>WEEK SUMMARY. 
The week started with the detector in OFF but finished ON (only SVX). 
 
 
MONDAY 
Access day: leak detected in the ISL East PC cooling line. 
Check if using a larger vacuum pump into the system to overwhelm the cooling line with the leak will give us enough flow to reach a point stable enough to run the system. 
 
TUESDAY 
Access day: 
Checking if the leak is close to the COT face. 
 
WEDNESDAY 
Access day: borescope 
The leak is inside the Silicon Baggie!. 
 
THURSDAY 
End of Accesses: Configuration of the SVX for 
running alone (without L00 nor ISL) and correct cosmic run test. 
First store with the SVX alone(Store 5435,LUMINOSITY: 137e30). No problems. 
 
FRIDAY 
Generation of Rasnik plots for checking the alignment after the accesses. 
Second store (5437, INITIAL LUMINOSITY: 171e30) 
 
SATURDAY 
Third store (5444, INITIAL LUMINOSITY: 147E30) 
Integrated dose alarm during scraping. 
Two bias pinkies right after the silicon was  
turned on: B5W3L4 and B3W8L2 
 
SUNDAY 
Fourth store (5450, INITIAL LUMINOSITY: 110E30) 
Integrated dose alarm during scraping.</pre>
