<pre>Giovanni suggested to take a run without the Muon trigger crate. 
So we did, but we get busy timeout after a few thousand events.

Went to the cryo area, and they say this problem is solved.  (I had asked them to call the control room when this happened; I don't know why this didn't happen)  In any event, we should treat all alarms as real now.

<pre>Slow controls are back. 
 
List of silenced alarms: 
   GAS systems: 720' platform NWA supply flow rate is 10.5 scfh 
                 and max is 6.5 scfh 
 Note for metric people like me (but not only): 
 an scfh is a standard cubic foot per hour. 
 
No other alarm is silenced.

Have changed clock from FREQ LOCK mode (clock freq locked to TeV RF, but phase not locked to TVBS) to NORMAL mode (both freq and phase locked) at Ming Song's request for CLC studies.  This does mean that if the MCR ramps the beam energy or otherwise alters the TeV RF, we will get clock errors that may in turn result in DAQ errors such as bunch ID mismatches.

<pre>LEvel 3 / CSL problem: 
 
Symptom:  CSL complains about "wrong data representation" when 
doing a COLDSTART.  It also says something about a non-current 
run number. 
 
Further diagnosis:  check CSL receiver display and check that 
the CSL still has connections in the partition you are using  
from a previous run. 
 
Problem:  Level 3 is still connected to CSL - or, perhaps these  
connections have been killed, but it was not done nicely. 
 
Solution:  Level 3 people can try to kill these conenctions from 
the Level 3 side - or CSL people can kill the connections from 
CSL side.   Either way you need an expert, and since this 
problem probably is accompanied with a death of the level 3 proxy, 
you may want to page Level 3 first. 
 
Boris is on his way.</pre>

<!-- Comment: Fri Apr 20 11;49;38 comment by...Ben -->
<pre>Actually,  it turns out the cleaning up level 3 solves
this problem by closing connections and restarting the level
3 proxy.

No experts necessary.  (The problem was that the smartsockets
client died for the level 3 proxy.)

<pre>Steve and Kevin switched the clock to the normal mode. 
There was uncoalesce proton beam at 980 GeV. Took a few 
runs for CLC (using the Min. Bias trigger) before filling 
the CLC East module with Isobutane starting at about 12:30 
pm today. 
 
The runs are : 1b7e4, 1b7e9, 1b7ec (taken using SoftEVB)</pre>

<!-- Date: Fri Apr 20 11:48:03 2001 -->
<pre>Level 3 problem sorted out. 
The rtclient connection of the level 3 proxy had died causing 
the proxy to die.  This meant that level 3 was not notified the 
run had stopped, and level 3 was still connected to the CSL. 
Therefore, CSL was complaining that the data was not compatible 
with the run number it had been previously receiving. 
 
Clean up Level 3 solves the problem on both sides : CSL/ Level 3</pre>

<!-- Comment: Fri Apr 20 12;45;08 comment by...TJL -->
Ming believes that there is a procedure for this, but doesn't know where exactly to find this.  He says the Ops Managers know,
so we page Steve Hahn.  No answer, so we repage.

<!-- Comment: Fri Apr 20 12;55;22 comment by...TJL -->
Repage.  Still no answer.  Try the cell phone.  No joy there either.  Del comes to the control room, and he in fact knows the procedure (it's #13), but it requires that a power supply be locked out by the ops manager.  That puts us in the same state - we need Steve here to do this.  The CLC folks want it done now rather than later.


<!-- Comment: Fri Apr 20 19;51;16 comment by...Steve Hahn -->
I finally showed up.  CLC CAEN was locked out.  At the same time, I unlocked the NWA CMP HV cables for the north muon wall chambers since their flushing after the work on the pit steel chambers was complete.  When flushing was complete (about 1500), I unlocked CLC CAEN and they repowered it.

<pre>Run 112640 done for Carla to investigate whether a hot tower 
is due to the cable or the channel in Dirac.  This is phi = 1, 
eta = 5 in EM.  To test whether this is a cable fault or channel 
problem, this tower was unmasked and the cable for phi = 1,  
eta = 5 was swapped with a neighboring cable in the back of  
crate b0l1cl00: slot 12, Aux channel 10 (J10) was swapped with 
slot 13, Aux channel 10 (J10).  Analyzing this run shows that 
the problem tracks with the physical cable.   
 
The cables have been swapped back and the tower re-masked.</pre>

<p> 
I have modified the logic behind SVX, ISL and L00 on the HV summary page.  A detector calls itself "ON" (stat = 9, color = green) if ANY ladder is fully biased.  If nothing is biased, it calls itself "STBY" (stat = 8, color = blue) if ANY ladder is at standby (typical standby voltages are 5% of full bias).  It only calls itself "OFF" (stat = 7, color = green) if ALL ladders are off.</p> 
 
<p> 
By the way, if SVX/ISL/L00 lose their heartbeats, I would like to be paged (266-2713) if it's normal working hours.</p>

<!-- Comment: Sat Apr 21 00;31;11 comment by...Alan Sill -->
This is a very non-standard definition.  How was it determined?
Such changes should not be done on a detector-by-detector basis -- all other detectors reserve green for being fully up!

    SE wedge 14 tripped. I tried to put it back at nominal 
    HV value. Apparently it does not hold the nominal value. 
    I decreased those values in 100 Volts. It seems to be  
    fine now. The current values are 5.5 kv for the anode  
    and 2.9 kV for the drift. The nominal values are  
    5.6 and 3.0 kV respectively.

<pre>For L2, we ran with Hevb, L2_torture_test table with  
CCAl crates and L1, L2 trigger. This table has low threshold 
L1 triggers that have a higher threshold at L2 or are prescaled 
at L2. 
  We get a L1A rate of 1.8Khz, a L2A rate of 100Hz, and about 
1% deadtime. 
  The change to the L1 interface firmware has fixed a problem  
that would show up on Clist. We also installed new Clique  
firmware to fix an error and haven't seen that error show up 
either. 
  A new Clist error was discovered which shows up after 
about 10-20K L2A.
