Showermax -  
 
1.  We swapped out the preamp interface board on West Phi=7   
(wire channels 32-63) which had all 32 channels dead.  
New board looks ok in DBANA.   Wire board 402 gain=-2 
 
2.  Cycled power to ccal06 and calibration problem with  
SMXR slot 5, SMX channel 1 (strip channels 32-53) fixed.  
 
3.  Swapped SMXR for ccal01, SMXR slot 4, SMX channel 2   
(wire channels 32-63) to fix calibration errors.   
New SMXR 564536 - 75 
Old SMXR 564548 - 87 
Cablibraions on these 3 ccal crates looked good.</pre>

<pre>MX access  
 
   Pcal10, slot 6, SMX channel 5 failed calibrations.   SMD  
board had a blown 7.5V fuse.  Swapped board and calibrations  
look good.

<pre>CPR Work: 
 
Trying to fix dead region in cpr Ephi=20, channels 9-16; 
swapped cables to see if dead region follows cables or 
electronics. 
 
SMX work: 
 
Swapped 4 SMD cards which were giving header errors during 
data taking: 
 
Wphi=6, ccal02, slot3 Smx2 
   old 564480-203 
   new 565291-326 
 
Wphi=17, ccal05, slot4, Smx5 
   old 564454-1E9 
   new 565294-329 
 
Ephi=9, ccal11, slot3, Smx6 
   old 565278-319 
   new 565298-32D 
 
Note after we swapped this smd card, this smxr failed  
calibrations for smx channel 3.  All the cable connections 
seemed ok, but reconnected stuff and cycled power on the 
9U VME crate.   After that, calibrations were OK. 
 
Pcal08, slot4, Smx5

<pre>ShowerMax Access Work -  
 
1. Fixed problem with ccal08, slot 3, smx7 (CCR card Ephi=0  
failing calibraitons) by recycling VME power supply.  
 
2.  Fixed problem with ccal05, slot 5, smx5, CES wire card  
in Wphi=17).  Channels were reporting error bits in   
header file and ped rms's were  very noisy in pedestals.  
Swapped SMXR.  
Old SMXR 564539-78 
New SMXR 564544-83 
 
 
3.  Fixed 2 signal channel  problems with calibration failures  
by swapping SMD boards in Ephi=6 and Ephi=11.

5.  Fixed 5 dead channels in CPR Wphi=20. cocked cable.  
 
6.  Concluded 7 dead channels in CPR Ephi=20 are disconnecte  
at detector which requires pulling NE arch to fix.  
 
7. Swapped SMXR in pcal02, slot4 to try to fix problem observed  
in YMON.  (not sure if SMXR is the problem - YMON occupancy 
plots look wrong for all channels in this SMXR (mostly based 
on low ranges).  Haven't heard of reconstruction problems, 
and powersupplies look ok.

<pre>Worked on single channel problems: 
 
19W - swapped wire preamp card to fix dead wire channels     
      59-63 
      Old card 384 -1 
      New card 413 -1 
19W   CPR & CCR cables were cabled backwards - fixed this. 
       
18W   reseated some cables at the protection diode circuit 
      for strip 1-16, and strip 16-32.   1-16 definately 
      seemed cocked, but cesped's looked ok.  16-32 didn't 
      look cocked, cesped rms's failing for ch 29-31. YMON 
      shows very low occpancy, but not dead. 
 
22W   Swapped CPR preamp to fix dead channels in 0-3. 
      Old card 510 
      New card 429 
 
4W    Dead occupancy strip channels 0-8, 59-63 (as seen in YMON). 
      Ped rms's look ok.  Checked cables, looked ok.  reseated  
      anyway. 
 
1E    Fixed cocked cable for strip channels which showed dead      
      occupancy in YMon, ch 24-29.  ped rms's looked like 
      detector not connected. 
 
3E    Fixed crate with wacky ped and assorted channels with  
      zero occupancy in YMon.   Nut driver had fallen across 
      rabbit supply touching ground lugs.  Fan was unplugged 
      and crate was very warm.   
 
Also tried to understand and fix the occupancy problem with the 
plug SMD crate West box 6, pcal02, slot 4.  
 
Checked voltages, ohmed cables, checked pedcal and peddat. 
Everything looked ok.  Swapped SMC anyway.

<pre>ShowerMax Access Work:  
 
Swapped SMD boards on the following central wedges: 
 
Wphi=20,  Old SMD 565372-377  Fixed calibration problem 
          New SMD 565174-2B1  
 
Wphi=22,  Old SMD 565068-247  Fixed calibration problem 
          New SMD 565168-2AB  
 
Wphi=4,   Old SMD 565307-336   
          New SMD 565296-32B 
  Hoping to fix data occupancy problem as observed in YMON 
  strip channels 0-10 have zero occupancy.   In previous 
  times, we have swapped preamps, SMXRs and checked cables. 
  ped. rms looked ok and calibrations were ok, but yet 
  data occupancy was zero.  (Need data to see if this fixed  
  the problem) 
 
 
Wphi=3,  Old SMD 565224-2E3 
         New SMD 565365-370 
   Again, hoping to fix data occupancy problems observed in YMON. 
   (Need data to see if this fixed the problem). 
 
Ephi=11  Old SMD 564270-131  Calibration problem NOT FIXED. 
         New SMD 565173-2B0    (Old board OK) 
            
         Problem NOT fixed.   Looks like there may be something 
         funny with the dac on range 2.   If I set the dac to 
         33500 (should be in the middle of range 3), some 
         channels (on all SMX channels) have 
         ADC around 9 cts range 3, while a handful of             
         channels have ADCs from 11-24 on range 2 for 1-2 cap     
         IDs.  
 
 
Wphi=15  Old SMD 564422-1C9  Fixed Calibration problem. 
         New SMD 565292-328 
 
 
WPhi=18 Swapped Preamp Board to fix 7 dead channels.  
        Channels now have ped rms ~ 3-4 cts. 
 
East Plug: Pcal08,slot6 and Pcal10, slot4 
 
Replaced 400 Hz Anderson connector on East plug servicing 
pcal08,slot6 and pcal10,slot4 to fix ped. rms problem. 
Looks good.</pre>

<pre>THIS IS FOR APRIL 11, 2002 
 
 
SMX access work  
 
Swapped 3 fanpacks on SMD crates to fix monitoring  
readback of fan speed.  West Plug box11, East plug box12  
and east central phi=22.   Between swapping the fan packs  
and reseating the termination boards and cables, the fanspeeds  
on these crates now appear at 100% in the PSM monitoring.  
 
Tried to investigate noise on CES strips West PHi=10, East   
phi=10, east PHi=1.  sympton is Pedestal sigmas of ces  
strips and wires are about a factor of 2.  YMON occupancies  
red.  The noise appeared on monday and was still   
present early in the day.  By 11am, it was gone.       
 
 
E,Wphi=10 and E,Wphi=1 is where the PSM monitoring ground  
attaches to the steel.  This is also where the bottom of  
the VME crate attaches to the steel.

<pre>In a test today, I ried turning the PSM power off, but there was

<!-- Date: Wed Apr 17 16:41:21 2002 -->
<pre>SMX access for Tuesday, APRIl 16, 2002 
 
Continued trying to understand noise now observed in CES on 
West Phi=10, East Phi=10, and East Phi=1.     
Noise is stil present (as observed by pedestal sigmas being 
a factore 2 -3 larger than normal), but we did the following: 
 
1. Cycled power on VME crate for 10W and 10E.  Had no effect. 
 
2. Used an oscilloscope to look at the noise on the low volt 
power supplies on 10W.  Observed 10mV of clock noise 
on the 7.5 V supply, but also observed this on 
12West where CES pedestal sigmas are ok.    
 
3.  Tried disconnecting the ground leads on the CES zipper 
tubing signals.  Had no effect.  Concluded noise is from currents  
in the steel observed by the CES chambers, but not CPR or 
CCR. 
 
We still don't have a clue as to what is injecting noise into 
the steel. 
 
We do know that the VME crate is attached to the steel at these 
wedges, but the lower VME crates are also attached to the steel 
and we do not see noise in those wedges.     
 
The PSM monitoring system as a resistor to ground on West Phi=10 
and West Phi=1, but not East Phi=10 and East phi=1,.  
Also since earlier tests of turning off the PSM voltage 
had no effect on the noise, we conclude the PSM is probably 
not the culprit.</pre>

<pre>Mon  April  29, around 10am 
 
As i walked through the control room on MOn Apr  29 around 10am, 
I heard aces talking about the SMX.   They had just paged me 
(although the battery in my pager was dead, i still responded 
in person). 
 
The SMD board in Pcal05, slot4, SMX ch1 was failing both 
charge injection and pedestal calibrations.     
 
I ran stand alone code to look at both pedestals and setting 
of the dac.   Everything looked ok.   Nevertheless, the  
calibrations were still failing.    I sent a request to 
the Ops Managers to replace the board at next access and I  
sent a request to Ops Managers and all calorimeter SPLs  
noting that all SMX data 
should be marked bad once the next shot went in and until 
we fixed the SMD problem.</pre>
