## Operations/Commissioning:CTT operations 

- Track-only terms have been working for quite a while; in use for physics triggers (TTK(1,x),TTK(2,x))
- Track+Preshower terms: defined & working, but thresholds not calibrated
- calibration runs taken before shutdown; hope to emerge from shutdown with calibrated thresholds
- L2 input:
- L2CTT operational since August 6
- L2PS included in DAQ during last week before shutdown; minor firmware problems found; should be fixed by end of shutdown
- STT: supporting STT commissioning; still chasing a few firmware bugs of our own, but almost converged
- FPS: last major part missing
- some reorganisation after Levan’s unexpected departure
- firmware (Stony Brook + Jamieson + Steve Linn) is making good progress; should be able to test partial chain next week

## CTT performance monitoringCTT_analyze 

-        Ctt_analyze package (Yurii,Makoto,Benjamin (summer student)):
-       - turn-on curves and efficiency plots for all CTT L1 And/Or terms as function of P**T**, phi, rapidity etc.
-      	- has been run on large sample of runs this summer
- 	- updated to include axial preshower

- # of tracks vs. sector number
- Red: tracks with axial preshower match
- -> there are preshower matches
- -> stuck & missing bits
- -> thresholds not calibrated

- Turn-on curve for 2 tracks above 3 GeV/c
- (used/studied for low-pT electrons)

## CTT performance monitoring

- CTT efficiency for TTK terms close to 1 (relative to offline tracking)

## CTT performance monitoringTrack+PS terms

-            Efficiency vs eta for track+ps with pT > 10 GeV/c

- - can see tan(theta) effect
- - questions regarding offline sample  and L1 - offline matching definition
- (i.e. definition of efficiency)

-            Efficiency vs phi for track+ps with pT > 10 GeV/c

## CTT performance monitoringZ ee study

**CTT performance monitoring****Z ********ee study**

-        Z  ee study  (Mike Cooke + Yurii):
-       -understand CTT (in)efficiency for physics objects
- 	-eventually using objects defined without the tracker
- 	- plots based on 400+ Zs
- 	- currently finding 92% eff.
- 	- relies on crate x13 R/O and run quality assessments; we know we missed some problems and mislabeled some runs...

-            Distance of matched L1CTT object to electron

-        Same on log scale

## Plans

- finish hardware work (SMT/CFT/CTT power supply disentanglement)
- finalize STT sender and CPS firmware
- add more L1 CTT/PS terms
- start FPS commissioning
