<pre>Plugged IB1W0 West Bore. 
Load box test ok, Wedge box test ok. 
Plugged in ok. Insulation on a low voltage cable was torn. 
Kapton tape around it. 
We leave the test for tomorrow, according to David's  
instructions, as this wedge has poor cooling.</pre>

Tested with Load box and WiB. 
We had to use the SVX and then L00 Load box, as the ISL one was 
 being used in the East Bore. 
Both tests passed. Smooth plugging. 
As requested by David we don't test this one.

<pre>owl shift east: 
--------------- 
 
plugged in SB5W4 successfully. 
 
CAEN control card for crate 10 (SVX NE #1) needs address of  
power supply crate 10 in order to plug in SB3W3! 
 
LIB and WIB tested IB4W1 (Andy will plug it in), everything was  
fine but we found a large current offset for L4 Bias1 (40uA  
instead of 200uA)! Talked to Doug and he suggested to plug it in  
anyway but to watch the current carefully. 
Layers 1 and 3 are central, so don't power!

<pre>Also I removed a routine, responsible for setting ramp up/down BIAS voltages values, from the code for the time being, which was  
being called during the GUI startup, since we are not going to change these values often and I am suspicious, that it may cause the spontaneous turning on channels in power supply.  </pre>

I thought we found out, looking into the log, that the power for
that wedge was not turned off successfully and the GUI reported
an error, coming from the CAEN crate. But the shift people, 
whoever was using the GUI at that moment, did not check, if power
really went off, relying that if one clicks the button,
everything goes smoothly.

Some things 
<ul>  
<li> I took L00 WiB to the second floor, behind rack 2RR34C 
(Southeast corner of trigger room) for debugging 
<li> B3W3 FTM needs to be replaced.  We swapped the Timing 
cable with that of B4W2, and B4W2 initializes regardless of 
the cable we use, B3W3 does not.  I was not able to swap the cables back because we spent too much time in the meeting talking. 
<li> L00 is currently plugged into the West DAQ.  The pluggers 
should check the system.cfg file in the directory they are 
using to be sure that <pre> b0svx06 </pre> is included if 
they are on the West <B>and not included</B> if they are on the 
East otherwise the east guys may turn off the Vrb the west guys 
are trying to read out.

<pre>I retested two SVX wedges which got blocked by another wedge to  
make sure that they still work. 
 
SB3W4: bias tested, I see the following:

       L3, L4: ~0.5 counts CM noise on phi side 
       rails (~1 count) in all five layers. 
       init and RO are fine. 
 
 
SB4W4: bias tested, I see the following: 
       L0,1,2,4 are ok (init and RO) 
       L3 gives a few CAP ID errors, looks like +49 in cell ID

<pre>tested IB5W0: LIB test: ISL box layer 4 gave DVDD over current,  
tested this layer with the SVX box (therefore no bias voltage  
and split bias measurements). 
L1 did not tripon bias over voltage but on bias under voltage  
(twice) or over current (once). The under voltage happened at  
142V, Imax=50uA, 100MOhm. Maybe the trip was ok but the message was  
wrong... 
 
Pay attention to this at the WIB test. 
 
WIB is connected and ready to test.

Tested IB0W5.  Everything looks good. 
 
Tested LB0W0.  Chip 2 of channel 3 has low noise (0.5-1 ADC).  Looks like dead or saturated front end.   Otherwise good. 
 
Tested IB1W0 (layers 0,2,4).   All chips have low noise (0.5-1.0 ADC) even when unbiased.  The cell ids are good, and the ramp ped setting move the pedestal.  Changing the BW settings from 1-7 does nothing.   Looks like front-end underpowered or missing PARST.   The currents for the ladders look normal, so I would guess that PARST is missing.    
 
I remove JC and re-did WIB test.  The noise is normal.  After re-plugging Jc nothing changed.  Left the JC partially strained-relieved and taped over SVX slots that shadow this JC.  THE JC NEEDS TO BE LOOKED AT MORE CAREFULLY.

I examined this FTM SN 162, PREP 565789, and find that its
Timing Signals look fine (compared to a neighboring FTM running
the same signals).  Using a DOIM'd DEM I find however
<UL> 
<li> Chan 0 reads back garbage all the time.  Reseating did not help
<li> Chan 6 bit 6 gets stuck low sometimes, intermittently.
Reseating did not help.
</ul>

None of this explains the failure to initialize...I will take this board back to PREP once I eat my lunch.

<pre>Since we were down for the computer reboot, rob roser had  
techs look at the 24 v supplies to see if they were causing 
the spurious quadlog trips.  Nothing was found.  It may be 
a flaky CPM module.  They would have replaced it, but  
that is connected with gas alarms somehow.

- 6C0 has its power supply partially configured like an  
        SVXII supply. 
    Its AVDDs are set to 8V (should be 7.6V for ISL). 
    Its 2VDOIM is set to 1.93 (should be 2.0V for ISL). 
    Its 5VDOIM is set to 5.43 (should be 5.1V for ISL). 
  These power supply settings could cause the DOIM light  
  levels to be too high. So far, we don't see problems, 
  but we could when we go back to lower temperatures. 
 
- In2 came unplugged after being covered by the inner cables. 
  Two HDIs lost their DVDD connection because the JC 
  connection got pried out atan angle. (It was reseated  
  and retested. No damage.) 
 
- West L000 "fell" out. It was checked as connected last 
  night but found to be unplugged this morning.

<pre>E Bore Summary 0800-1600 
 
Dave Stuart spent much of the day testing ISL ladders 
that had been previously plugged. 
 
1430 tried to perform WIB test on IB5W1 (JC dressed 
on previous shift.)  Could not initialize WIB (or read out.) 
Swapped to using FIB timing cable from IB4W0; still 
could not initialize or read out.  (This leads one to 
believe the problem is in the WIB, though it's not 
ironclad).  Eerily similar to difficulty yesterday with SB3W3.  ADF tries to recall any karma-reducing activities of the past week but nothing comes to mind.  Steve N. verified that clock 
signals are getting down and blinky lights work. 
Petra, the last person to have successfully used the WIB, 
also could not get it to work. SDA will try other WIB /  
examine WIB #2.</pre>

channel 2 goes in overcurrent for DVdd 
We tested with Matt's box. Impedance with PS off looks normal 
 at the bore end.  We tested the power supply with Matt's cable 
 bundle and it still has the same problem. Therefore it is 
due to the power supply, that needs to be changed at next PS

<!-- Date: Tue May 8 21:22:25 2001 -->
<pre>We retested IB5W3 and found a very odd problem. Three of the 8 ladders we 
tested on this wedge have low noise at standby. This noise is not 
anomalously low like a dead front end, rather it is the same noise you 
would expect to see if the ladder were biased. We verified that they were 
not getting bias by unplugging the the bias cables from the supply end and 
routing the supplies bias outputs to a load box. The load box showed some 
offset (~5V when requested 2V at standby), but that is certainly not 
enough to cause this problem. With the bias cables unplugged, one of the 
three ladders behaved as expected. The other 2 still had low noise. 
 
We retested the supply with the load box and a different cable bundle. It 
was ok. We need to probe further tomorrow. Until then, IB5W3 should not be 
plugged over. 
 
We tested IB4W3. It was not plugged in completely. The leftmost pins were 
not mated. These carry the ISL bias for layer 0. Connected it and strain 
relieved and it tested ok. 
 
</pre>
<!-- Author: david -->
<!-- Comment: Tue May  8 22;49;51 comment by...Petra -->
I remember that IB4W3 had some difficulties on the left edge to 
be plugged in completely. At the second attempt we thought it was 
well plugged though. I think it was one without a rail on that side, so we should find a solution for these railless wedges soon.

<table border=0><td><tr><td bgcolor=#e0e030><pre>Swing Shift--East Bore.  Finished plugging S3IN(SB3W3).  The junction board passed the WIB test with flying colors, but not the final wedge test.  The big problem is that Layer 4 does not completely initialize.  There is no readback from the initialization and the analog current does not increase enough.  On some events the layer 4 reads out the first four chips in the chain, but never more and most events are complete garbage.  In addition there were some CAP errors on layer 0 which may be due to a partially stuck bit.  It would be worthwhile reducing the DOIM voltage a bit and see if this goes away.  Layer 3 also dropped its full readout some of the time when operated with the other 3 working ladders but never by itself.  Again this may be fixable by power supply tweaking.  Since we had no further ideas we moved on.  </pre></td></tr></td></table>

West side.  Goal is to test re-test ISL/L00 JCs which have had work done on SVXII JC below them.  
 
Perform visual inspection of ISL/L00 JC connections: 
<ul> 
 <li> <b>L002</b>: Looks ok 
 <li> <b>IN2</b>: Unseated by about 1-2mm.  Skewed. 
 <li> <b>OUT2</b>: Unseated by 2-3 mm evenly across all pins. 
 <li> <b>6C1</b>: Looks good on the left side.  Can't see the right edge           at all. 
 <li> <b>L001</b>: Right edge is unseated by about 2mm.  Left edge is well seated.   
 <li> <b>IN1</b>:  Looks ok. But Bolla bands too tight on front bias connector and missing Bolla bands on 2nd. 
 <li> <b>OUT0</b>: 2-3mm gap on right edge, 1mm gap on left edge. 
 <li> <b>IN0</b>:  Looks ok.  No Bolla bands at all. 
 <li> <b>L000</b>: 1mm gap on top edge, bottom edge looks ok.  Definitely still has connectivity.  But Bolla band too tight on front bias connector and missing on 2nd. Has wrong size clips for the FIB command cable--they are too short to hold the connector. 
 <li> <b>OUT5:</b> JC connection looks ok, but the FIB command connector is not well seated.  This is because the clips are too short as in L000.  Bolla bands too tight on front bias connector, missing on 2nd. 
</ul> 
 
I am reluctant to fix any of these problems as they are probably  not fatal.  On the other hand, we may want to address them, so I 
have <I>decided not to plug in S11IN (SB2WB)</I> which has passed WIB test and is ready to plug. 
<P> 
Clearly, we need to come up with something to prevent these JC from becoming disconnected.  David had some suggestions, but I don't think I should try and implement them right now.  I would rather wait until we can discuss things tomorrow. 
<P> 
We can't safely (even with boroscope) get at connections on ISL/L00 JCs that have had SVXII plugged beneath them.  Without seeing that the connections are ok, I can't safely re-test these JC.

Sorry, not able to accomplish much.  Will move on to bundle testing.

My comments on L00-b0-w0 and "out-5":
<ul><li>where the cable-ties are missing, the glue was used to hold the connector in place.
<li> the short clips were accepted as a standard and it was
 decided to use them instead of removing them. In addition a 
 very little drop of glue was used for the sense connector.

I found that the CAENvolts.dat file had x's next to all five
layers.  This will prevent the layers from ramping up.  Jean
tells me that it is a policy decision that we leave the x's 
there and remove them before testing.

tested SB3W7 with LIB and WIB and found BAD POWER SUPPLY  
(see portcard elog), replaced FIB (and other?) cable(s) is  
working fine! 
 
tested SB4W6 with LIB and WIB and found OFTM channel 3 problem,  
CAP ID errors (cell ID +8), which stays with OFTM channel rather  
than orange cable/HDI combination! 
 
tested SB5W6 with LIB and WIB and everything was found ok. 
 
SB4W6 and SB5W6 need Gino's ground bridge soldered as soon as  
possible and the SB3W7 power supply needs to be replaced even  
before that. Then all three wedges can be plugged in! 
 
Here come a few other issues from the night: 
- - - - - - - - - - - - - - - - - - - - - - - 
Matt's breakout board shows strange things at least on  
layer 0 and 2, not clear which sense and which ground to  
use and voltages were 0 (=wrong). 
 
I think I broke one of the blinky lights boards, its LEDs  
down shine anymore... 
 
We found in all three SVX wedges, that layer 0 and 1  
accept up to 115V bias voltage and not 100V as written  
in the check list, please change that... 
 
At a certain point around 5:30am the GUIs lost communication  
with iFix and rebooting of svxinter didn't help, however,  
while being logged into svxinter and trying to start the GUI  
I saw that crates 7 and 8 gave errors. I took those crates  
out of the CAEN.map file and then we could continue running.  
I just now (that I am upstairs) recognize that the related rack  
tripped on a fan failure (NWB). It did not give an alarm in the  
control room! </pre>

Layer 0 and 1 hardware limits are set to about 170V(+-85),
which is the burn in value.  If you expect a lower limit it
has to come from software.

I checked this supply using my load board.  I could find nothing
wrong.  I measured all 12 low voltages and all 5 bias channels(
three combinations each).  I'm not sure what is wrong here.  Could you be more specific.  The comment that 0's were measured does not specify which channel(AVDD, DVDD or Bias).

<!-- Comment: Wed May  9 12;51;33 comment by...Andrew -->
"svxinter" is not needed to be rebooted, if you get a message on the GUI display: "Lost communication with iFix". It means, that the GUI did not get an update from iFix, what bulkheads are enabled with interlock. Possible failure could be smartsockets server is down.

sitting half out of its socket.  These are located on the Rack Protection DIN rail, on the bottom of the rack 3-4 inches inside 
the rack frame.  The most likely cause is that someone kicked it while removing an enable.  Reseating the relay and giving the 
Rack protection system some time to recover fixed the problem. 
<B> Please  be careful climbing around the Racks!</B>.
