Minutes of the June 9, 2005 US ROD meeting
A report from Wim and Guido on the results of their studies
of I2C errors at UCSB and FNAL is
available.
Follow up on action items and new action items
- Lt SW bug that causes bad pulse shape. Valeri on it.
May be OK if change parameters of CMN subtraction.
Jim fixed at UCSB, need to propagate to FNAL.
Still needs to be done at FNAL
Done
- FNAL: Tested bunch of new HPK rods in SR. Two out of six have broken or shorted
termistor. Strange because Lenny says that these are chcked on rod frame.
Possibilities: bad check on rod frame, or bad connection through flat cable,
or bad DCU on hybrid.
Check module fast-test
Probe with multimeter
Modules in question are on rods.
Old measurements OK. Will look when the modules come off rods.
-
FNAL: some bad DCU voltrages on SR, but not on MR. Needs fix.
Not clear. Wim committed fix.
Check env, then PIA reset. Ryan to double-check
-
Javier has new DefectAnalyizer. Steve did not know about it.
Get new code.
Done
- According to Sandro's email, there should be no
I2C transactions in broadcast mode.
Wim to fix Lt.
- New: V29 at FNAL runs faster. Why?
FNAL
5 rods modified (jumpers or 0 ohm resistor) in 3 hours.
Need to be careful not to damage.
Some errors reading DCU.
UCSB
No errors on modified rods.
