h1. Diagnostics

Can we do another analysis/diagnostics meeting today, 14:00. I added Ao

into the mix for the Cerenkov data we have taken in the last couple of

weeks. Norman, I can let you in if you need me to (I am back at RAL).

We will be in one of the usual meeting rooms in the Atlas building,

using phone:

I will post agenda, slides to:

* Tracker-to-tracker alignment - Melissa/Chris Hunt/John Nugent

** Straight tracks data this weekend

* Tracker alignment to field - Chris Rogers/Sophie

* Cut-based beam selection vs 2015/01 data - Tanaz/Scott Wilbur

* Ckov momentum scan - Ao Liu, Durga Rajaram

* Full PID vs 2015/01 data - Celeste

* PID detector alignment - Francois

Cheers,

Chris

Celeste Pidcott - looking at straight tracks data

Tracker-to-tracker alignment

Chris Hunt

* Looking at different runs; looking at data taken on Monday 28th September; can we measure remnant fields?

* Trying to get final set of numbers; ROOT is segfaulting for no reason, so no official new results

* Very few issues with the data

* 200 MeV/c straight muon run, 300 MeV/c straight muon run, diffuser in straight muon run; no diffuser studies on Monday 28th

John Nugent

* Pulled low emittance high momentum run from 28th September, attempting to process it with millipede

* Durga will email John URL of the reconstructed data set

* Pushing through millipede, will get numbers

Tracker to field

* No update

PID selection

Tanaz Mohayai

* Two interesting features from the TOF plots and TOF vs momentum plots - "bridge particles" between electron and muon peak

* Working through the electron plot

* But working shifts and COOL2015

* Suggest looking at data from last night

* Very high p particles...

Ckov

* Never got to sufficient momentum that pions turn on the ckov

* Select electrons muons pions using TOF, looked at PE yield, below threshold it is consistent with noise 270 MeV/c turn-on in pions

** Hole in the 200 MeV/c momentum range

* Not seen muon plot

* Is it consistent with historical data?

* What's the turn-on for muons

* Ckov data last night; needs analysis; did not go to the high momentum region

Global recon

* Still waiting on track matching

PID detector alignment

* Q789 off data
