Some
thermistors are read through DCUs, some are not.
Non-DCU-thermistors are tested with Ryan's box. The new UCSB SRT
GUI has provisions to enter info in SRT
text file. The script that makes the XML file needs to grab this
information and stick it in the XML file.
A first version of this exists at UCSB. Careful, because XML
generation runs after MRT, SRT data is on
different computer. At UCSB disks are nfs-mounted, at FNAL
afs-mounted (?), not a big problem but need
to pay attention.
Action Item: FNAL to install new
SRT GUI from UCSB.
Info from DCU-thermistors from Ryan's macro, except that those of
modules 2&6 are not there because
read through DCU on CCU.
Action Item: Ryan to modify his
macro to flag these also
Old (double) ICC4 cards were jumpered
wrong. New ICC cards have problem fixed.
Somewhat arbitrary decision: a
good rod will need to have 2 out of 3 non-DCU thermistors functioning.
Other Action Item: Check
resistivity of non-DCU thermistors after power cycling. On a
couple of rods, both
UCSB and FNAL.
XML
File
We went through a sample XML file to
understand what is going into it. All the Action Items in this
section should be followed up by Steve.
There is now a section for each module for 1st warm, last cold, and
last warm
Action Item: Add results from 1st
cold
Right now, only storing PeakInvOn info.
Action Item: Add DecInvOn.
Also, make sure that they are labelled sensibly
We all thought that we should have more information on what modules are
in the rod and how Lt was run
Action Item: Add module ID as well
as module position. Append settings.xml file
Other Action Items about XML files:
- Change the average values reported from averaged over a module to
averaged over a chip
- Add channel-by-channel CMN, raw noise, ped
- Take a sample XML file and label every entry with an explanation
(in English). Post on the web somewhere.
- DCU temperature readings should be stored only at +20 and -20
Scenario
Currently W -> C -> W -> C -> W -> C -> W ->
C ->W (C=cold, W=warm).
Takes 2 days at FNAL. Longer at UCSB, recently it has taken as
much as 10 hours to go cold.
Action Item: UCSB to figure out
why it is taking so long
Decide to keep this scenario, and decide to continue doing full suite
of tests, with results stored in root file, at each stage.
Action Item: add a CalProf run to
SR scenario, make sure that it shows up in Ryan's macro (Ryan)
Criteria
for bad channels
We reviewed cuts proposed by Steve. They look fine.
UCSB still has somewhat high CMN, which means that opens are flipped,
and are flagged as "unkown" in noise tests, then flagged correctly in
other tests.
Action Item: UCSB to try to lower
noise
Double sided rods
As soon as DS rods modules are avialble, build DS rods for Duccio's
request
Action Item: FNAL to build one
DS_L ID=1 and 3 DS_L ID>2. UCSB to build one DS_L ID=2 and 3
DS_L ID>2
ICC
cards swap
We all agree that best done at CERN.
CERN bare-rod testing done with SW we do not have, at higher speeds,
etc.
Action Item: Claudio to contact
Duccio, see what their thinking is
FEC
Software
FEC SW V3 now exists. We have V1.something + patches.
Aim of new SW is to be same as XDAQ,
+ add functionality (mostly for
debugging).
Digital Tests
New version of Lt (v30) will have ProgramTest in it, can be made part
of scenario.
Action Item: Claudio to remind
Marchioro that we need well defined digital tests list
Residual
I2C errors
Yuri: Latest FEC SW + ProgramTest, 6 rods: errors 64 and 68.
Errors persist with two rods, go away with only one. Consistent
with hypothesis that these are ring errors. Similar effects at
UCSB.
Wim trying to install FEC SW V3 at FNAL.
Action Item: Yuri to schedule joint meeting with Guido, Wim, Frederic
for this Thursday on VRVS.
Header
Errors
Still seen at UCSB, not in a while at FNAL. Will be discussed at
meeting above.
Noise Study
How can we contribute to decision on ICC cards grounding?
Action Item: FNAL SR test with
Option 7 cards with and without ground connection. Remember to
not let cooling pipes floating
Optical
FEC
Still requires some mods at CERN.
Do we want them. Yes, if we get it in time, and we get help in
installing.
Spares
UCSB needs more jumper cables and power cable
Action Item: Steve to email Lenny
One Delphi supply at UCSB is flaky.
Action Item: Claudio will write to
Duccio
Rod Grading
If we see a pinhole, immediate rework.
ARCS module grading criteria:
- A 1% or less bad channels
- B 1-2%
- C >2%
- F HV problem
For rods DefAna grades each module. After lots of discussion, we
agrred on the following rod grading:
- Pass: No C modules. Leakage current for all groups
less than 20 microAmp. 2 out of 3 non-DCU termistors
functional.
- Fail: otherwise
Action Item: Steve to implement in
XML file
AOB
Action Item: FNAL needs to follow
up on modules that were removed from rods for various reasons
Action Item: Both UCSB and FNAL to
prepare "anecdotal" list of problems encountered in July production
