ACORDE REPORT

Pedro Podesta

UAS Mexico


Acorde report

Outline

  • Geometry ( No changes)

  • Alignment (No changes)

  • QA (No changes )

  • Shuttle (In progress)

  • To do


Acorde

ACORDE

60 modules

Resolution= (2 m x 0.4m x 0.1m )

We only know is module is fired

PMT HV ~ 900 V

Efficiency (HV)

Pulse discriminator hardware controlled

Upgrade underway (at least one Year)


Geometry

Geometry

AliACORDEv1.cxx

Well description of the detector.

Modules, supports, case plastic etc ..

It is included by default now in the reconstruction/macros

Thanks Federico …


Survey alignment

Survey Alignment

  • AliACORDEAlign.cxx

    The survey data

    Survey_865479_ACORDE

    Two points per module (will be better 3 to have the plane )

    Alignment is per module (60 align modules )

    Only z coordinate taken for now.

    No overlaps, average difference is 2 cm ..


Alignment

Alignment

Macros

  • MakeACORDEFullMisAlignment.C

  • MakeACORDEResMisAlignment.C

  • MakeACORDEZeroMisAlignment.C

    Using gaussian distribution needed some real number

    From the survey


Alignment1

Alignment

  • Need to check overlaps

  • Put the data in OCDB

  • Put x,y position or correct geometry.

    Thanks to Rafaelle


Acorde report

QA

  • Remove all histograms from digits, hits , Energy.

  • Keep only one histogram.

  • We monitor rates online any big change is noticed quite soon, as for examples last week make a firmware update we realized something was wrong .


Shuttle

Shuttle

  • We had some inputs missing from DCS and the preprocesor was failing it was a problem with ECS and the start of run.

    It was fixed (July 2008 ). Thanks to Mario Ivan chiara, Latchezar an Franco. For me was far from clear.

    No plans to change DA or update.


A few remarks

A few remarks

  • We need to include the QA objects in the OCDB and also alignment object

  • We do not miss any data from DCS,DAQ or HLT

  • For now we have no difference for high low flux runs, since ACORDE is for cosmics physics.

    - Due to the way ACORDE works we have no way to change threshold online. So for low or hi flux we can not change parameters, since the fired trigger will not be ACORDE.

  • RecoParams still missing.

  • Preprocesor and DA will not change

  • No second pass calibration for us. We have measured efficiency and need implemetation


To do

To do

- Finish alignment

- RecoParams

- QA Reference

- Include the real efficiency

All comments, very welcome
