Fiber Tracker Meeting Minutes
January 13, 2004 - 10am, farside
- Current Status : Borcherding
- figured out recent problems with CPS axial board:
- Fred put wrong clockgen in it -
CPS axials need a special clockgen
- interesting behavior in this state:
discriminators don't fire
- so, remember, for CPS axial boards a special clockgen
has to be put on them!
- CFT Status : Warchol
- talk slides
- problems with 3B4...bit 4 is flaky
- what to try now? spare cable swap? change slots? another board swap?
- if a short access, try a cable swap
- instabilities
- offline we don't notice this because the shifts are all below
the 20ADC count cut
- already tried recalibration to make this go away - doesn't seem
very helpful
- looked at power supply, and there is no major shift corresponding
to this ADC change (but still could be due to a small
transient 'spike')
- CFT light yield update : Boeriu and Jabeen
- Boeriu:
- talk slides not yet available
- not sure program is doing the right thing:
- there is confusion over what the distribution is showing if you look at
ADC values from 0 to 511.
- have to look at just 256 to 511 to get a single-peaked distribution
- Jabeen:
- CTT Status :
- still have to understand all these new 'features'
- also, some discrepances between VSVX data and crate x13 data
