<B>Very Odd FTM Problem on East IN4 (B4W4)</B><BR> 
Joel and I found on this wedge using the Wib a very strange 
problem.  We know the following facts: 
<ul> 
<li> FTM Chan 4 drops readout with either HDI 3 or 4 of the 
WiB, with either cable. 
<li> Until we changed to the new "C4 fix" firmware, this also 
caused the C4 error on the other channels 
<li> <B>Here's the strange part</B> If we disable FTM Chan 4 
and turn off the power (or not) of its corresponding HDI, the 
Fib does not send data to the Vrb <B><I>on any channel</I></B>, and we end up 
with a READ BUSY condition.  We did not try to break the DOIM 
connection, although that might be something to try. 
</ul> 
To me, this seemed like the Fib was ignoring its enable flag, and expecting 
but not getting data on HDI 4, so was not sending any data.  However, we changed the Fib and this did not solve any problems. 
 
To fix this, I would try 
<ul> 
<li> the obvious: swap the FTM 
<li> maybe break the DOIM connection and disable the channel and 
see if that makes any difference 
</ul> 
In the meantime, one can get around it and test 4/5 channels then 
swap DOIMs around to pick up the last one, then plug the wedge (which 
Joel intends to do, with Gino's help) by leaving Channel 4 
enabled at the Fib but disabling it at the Vrb.  There are two 
ways to accomplish this: 
<ul> 
<li> Leaving Chan 4 enabled at the Fib, clicking on 
"Set Defaults", then afterwards turning off the Vrb Channel 
by hand.  You will want to not look at the histograms for the 
channel you turned off 
<li> Making Channel 4 disabled at the Fib, clicking on "Set Defaults", the afterwards enabling the Fib Channel.  We did not 
use this method, but it should work. 
</ul> 
 
I think this will be done to get IN4 tested and RTV'd tonight. 
Joel's preference was to not change the FTM, so we will get to 
that next week I suppose.  There are spare FTMs now in the  
boxes.

<table border=0><td><tr><td bgcolor=#e0e030><pre>ISL EVENING SUMMARY FRIDAY 25th MAY 
 
Tested and finished 6C2 on West 
 
Found and overcame FTM problem on East In4 (tested layer 7s together using channel 3 to read HDI 4 and channel 4 masked at VRB, then layer 6s individually). 
 
While testing East In4 layer 3 temperature exceeded 24degC. No trip, so we probably switched off fast enough (check IFIX logs around 3am) 
 
Finished East In4 and removed cables. Took a bit of Gino's shift - sorry. 
 
ISL/L00 FINISHED ON EAST!</pre></td></tr></td></table>

<table border=0><td><tr><td bgcolor=#e0e030><pre>Summary WEST bore 0:00-8:00 
============================ 
 
SB1W10 plugged, it was already LIBed and WIBed yesterday, so I  
just plugged it in and I found the same problem reported from  
the WIB test, namely that OFTM channel 2 is bad (data run saved). 
 
SB0W10 plugged, was already LIBed and WIBed earlier today.  
This wedge has now the ground connection with SB1W10. I see  
absolutely no rails (even without the ground bridge :) 
When reading out all five layers simultaneously we get Bxing  
Bytes errors, when reading out one layer at the time, everything  
is perfectly happy! 
 
LB0W4 plugged: LIB test already done before. WIB test (with L00  
WIB) works just fine, plugged, has to be tested by ISL/L00  
personnel. 
 
IB1W5 plugged: LIB tested ok, a few (hopefully) little things  
(voltages out of range, current offsets) seen, nevertheless  
went on to the WIB test: found (again) problem with WIB#2 layer  
3, which doesn't init. Tested all OFTM/DOIM channels ok.  
Plugged, needs to be tested by ISL personnel. 
Careful with this guy, especially that it is not RTVed yet:  
it's left alignment pin is bent towards the outside. I needed  
Gino's skillfull hands to get them engaged... So this wedge better get's not unplugged anymore! 
 
Started work on IB1W4: JC connected to LIB, crate is on, enable  
plugged, iFix activated, everything is ready for the LIB test.

<pre>EAST BORE NIGHT SHIFT REPORT 
 
Plugged tested and RTVed SB5W9 (ch7 bit 1 on OFTM is stuck LOW) 
Plugged tested and RTVed SB4W8  
 
Left LAST wedge on this side SB5W8 to next crew.</pre>

<pre>CAEN crate on SE Bottom Top (#13) 
Turned On in order to power SB5W9. 
At a certain point we start to see on the gui the following  
WARNING: SVX B4 W7 is OFF but currents are bigger than 50  
(or something else with the same meaning) 
on my next entry I will try to put a postscript of the spy 
 program with the I and V values that are completely crazy. 
If values were correct the power consuption would have been high 
 enough to show up on the temperature plots available on IFIX. 
The plots are completely flat. 
Very likely this problem is due to a weird state of the 
 communication with the power supply and has nothing to do with  
the actual voltages at the output of the board.

<pre>As promised here is the list of voltages.
Unfortunately the 3 wedges still to be plugged on the east side
had their PS on the same crate with this one so in order to 
ensure safe operation (in agreement with Mat) this PS has been
unplugged (crate 17 is assigned to it on the CAEN.map file)</pre>


<!-- Date: Sat May 26 09:09:15 2001 -->
<pre>We should probably test again SB4W7</pre>

<pre>WIN4 plugged.  Ch 0,2,4 tested OK.  Ch. 1,3 not tested due to slow DAQ problems.  CHANNEL 3 HAS A BAD OFTM (passed flashlight).  Moving to 1st floor/control room helps but still slow/choppy response.  Borderline for testing cooling challenged parts but probably OK to test them from control room (close to crash button).  Joel will test thusly. 
 
WL004 tested, AOK.  RTV'd 
 
WIN5 began testing on 0,2,4.  Getting 0's reading back init.  Doesn't look happy.</pre>

<pre>WIN4 0,2,4 also need further investigation. Exhibiting "low noise" and readout errors.</pre>
<!-- Date: Sat May 26 21:38:43 2001 -->
<pre>The plan for tonight, saturday-sunday may 26-27: 
 
East: measure light ouputs, debug B5W5. 
 
West: 	ISL finishes In4-5 
	SVX Plug S9CEN. 
	If before 11pm, call Matt to change power supplies 
		then continue with rest of west (all available) 
	Else finish S9IN and wait for morning 
 
	NOTE: S9IN has new FIB timing cable under platform 
		to be routed by taping to cable ducts and 
		run into bore.

<pre>EVENING SUMMARY 16:00-24:00 SATURDAY 
 
Jim Patrick killed a lot of netscapes, reconfigured some PCs and generally got things working up to speed again. Please keep him informed if this changes. 
 
WIn5 still doesn't initialise. May need to remove and retest. 
 
WIn4 has readout errors and low noise. Swapped timing and DOIM for channel 0 with next-door FIB (WIn2) and looks exactly the same.

<pre>second-hand summary of 1600-2400 plugging shifts: 
 
  - Lester measured light outputs on the east 
 
  - Joel spend his shift wrangling w/ the DAQ; eventually 
    got Jim Patrick in here; took him a couple hours but 
    things now look back to normal 
 
  - David will try to finish off IN4/5 for the ISL West 
    and then Petra will start more SVX work on the West

<pre>swapped OFTM in b0fib01, slot 11:   
old OFTM: #159, 565880   
new OFTM: #161, 565877   
 
the old OFTM has something wrong with the    
lower half commands, nothing initializes there; 
I put it back into the cabinet 2nd floor.</pre>

<pre>and swapped it back since the OFTM was not causing this problem...</pre>

<!-- Comment: Sun May 27 06;32;24 comment by...Petra -->
<pre>NOTE that the FIBs of slot 10 and slot 11 in fib01 are swapped 
with each other for debugging. We did not swap them back since 
both should work the same in either slot...</pre>

====================== 
 
I plugged in this wedge. Everything went smoothly.  
All layers look depleted when bias voltage applied. This is   
an extremely clean wedge, no grass at all, no funny shapes!  
 
Replugged after quick LIB test (ok).  
Seeing low DOIM currents: 810, 1620 uA.  
OFTM channel 6 bad.  
See about 1 count rails, slightly decreasing with time!  
The only thing bad: second phi-side-chip on L2 has very low   
noise/dnoise and high (50 counts) pedestal/last pulse!

<pre>This wedge is West S9Cen = SB1W9</pre>
<!-- Date: Sun May 27 08:57:33 2001 -->
Continued the evening shift's testing of West In4 and West In5. 
There are both in the same fib (In4 is the top). 
<P> 
In4 had the low noise problem. 
In5 would not init (failed readback and currents did not change). 
<P> 
Found that In5's init failure problem was due to the OFTM by swapping the 2 fib timing cables. But then, we got scrammbled data. Swapping the OFTM fixed the init problem, but then we were left with scrammbled data on both IN4 and In5. 
We swapped the fibs between IN2/3 and In4/5 and that made no difference. Left the fibs in this swapped state. Concluded that the scrammbled data is not the oftm so swap it back for now. 
<P> 
Test all 10 channels of IN4/5 using channel0 of the L002 FIB by swapping the FIB timing cables and DOIMs over. All ok. 
<P> 
RTV'd. 
<P> 
Outer ring is done!
