Fiber Tracker Meeting Minutes

talk slides
in most plots, red is new timing, blue is old timing
page 10: has the layers mis-labelled. Left to right starting on the top row, they are: 1,3,5,7,(next row) 2,4,6
page 13 is the layer efficiency as a function of the fiber number where the bins are SVX layers
page 15: "Layer efficiency" is the overall efficiency

talk slides
Note: plots are are not those shown at the meeting. Data was re-run to get better statistics and include only axial layers
What is a multiplet? three or more hits
lambda is the compliment of theta
Key for Supersectors:

Pulse height distribution of clusters: plots
Pulse height distribution - contrast VSVX on and off: plots
Counts of Singles and Doublets vs. tan(lambda), lambda, and eta: plots
Counts of Singles/Doublets and Multiplets vs. tan(lambda), lambda, and eta: plots

these plots jive with what Makoto was saying - a shorter path length (nearer zero), means more singlets.
if there were 2 doublets for each singlet, one would expect the histogram to be around .5, but the lowest value seen here is 0.8

y-axis is average ADC count, so is higher when overflows included (right-hand column)

Average ADC of Singlet in 5 Supersectors: plots
Average ADC of Doublet (high ADC) vs. tan(lambda), lambda, and eta with 254 ADC included: plots
Average ADC of Doublet (high ADC) vs. tan(lambda), lambda, and eta without 254 ADC: plots
Average ADC of Doublet (high ADC) in 5 Supersectors without 254 ADC: plots
Average ADC of Doublet (low ADC) in 5 Supersectors without 254 ADC: plots
Average MAX ADC of Multiplet vs. tan(lambda), lambda, and eta without 254 ADC: plots

CPS and FPS personalities are in
all L1 and L2 senders are in and are behaving in the sense that they are not messing up level 3
FPS firmware development is resuming
were able to put all boards to be read out into crate x13 as of yesterday
CTT

new firmware for CTTT in (tried three weeks ago, but had to back out)
reason for problem before: some terms were not defined correctly. Levan fixed them.

occupancy related terms (like THT) are being offered as components of triggers if you want to veto on too much occupancy
Michael Begel is worried if this would mess up luminosity calculations. He wants to put each into it's own exposure group, but space is limited
discussion continues on what approach to use

cassette work? only if we warm up completely
we will pull and modify all AFE boards to fix unused channel and add frequency controller
